Introduction
Thank you, and congratulations, you now have the original Tracking Nock for your pursuits in the great
outdoors! This product will help you recover more game with less grid searches, bring back your meat in
less time, with less spoilage, and less risk from predators finding your trophy before you do.
The Bloodhound XTN tracking system consists of 2 parts, the handheld Tracker and one or more XTN
tracking nocks. The Tracker can be used with up to 6 different tracking nocks which are identified on the
nock and on the Tracker’s display as numbers 1 through 6.
The XTN tracking nocks are installed in the rear end of the arrow / bolt shaft to replace your existing
nock and remain dormant until launched. Once launched from a bow or crossbow the XTN tracking
nocks lights up and begins transmitting a digital identification code to the tracker every 1.5 seconds.
During a well-placed shot on a game animal, wings integrated into the tracking nock collide with the
target and pull it out of the back of the arrow / bolt shaft as the arrow / bolt passes through the target.
The XTN tracking nock’s retention mechanism opens inside the animal’s body cavity as it is pulled from
the arrow shaft. Even if the arrow does not pass through the animal, the nock will still transmit and light
up.
Once activated, the handheld Tracker can lock onto the XTN tracking nock transmissions, giving you a
directional indication pointing to the tracking nock’s location and a signal strength indication that allows
you to know the relative distance from your location to the tracking nock or game being tracked.
Getting Started with your XTN Tracking Nock installation.
1) Charging.
IMPORTANT: Charge your XTN tracking nocks before first use.
CAUTION! Always insert the XTN tracking nock into the USB Adapter with the nubs (bumps) on the
wings to slide along the openings in the adapter made to fit these nubs. Inserting incorrectly or
backwards will damage the tracking nock electronics permanently.
The XTN tracking nock may be inserted into the USB Adapter with or without a pin nock inserted on pin
at time of charging.

Inserting the XTN into the charger will show the status flash as described below in Battery Status
section. If the battery needs charging, then the XTN will emit the charging flash which is a quick double
flash once per second. When done charging the flashing will stop. Taking the XTN off the charger and
then putting it back on a few hours later will likely result in it charging for a few minutes, maybe 10- 15
minutes before it says that the charging is complete again. It will register 4 bars for weeks, even as long
as a couple of months after being charged. Once fully charged or removed from the charger at any time
the XTN returns to standby mode.
2) Bushings.
There are multiple bushings in your kit to properly fit the XTN tracking nock into an arrow / bolt shaft
with inside diameters of .244” (S) or .246” (GT) for compound bows, or .285”, .297”, and .300” for
crossbow bolts. There are 2 times the quantity of bushings included in your kit in case you would lose a
bushing during insertion or removal of XTNs from arrow shafts.
Compound bow arrows with .244” ID or .246” ID: one bushing should be installed onto the front ring
cutout of the XTN tracking nock. There is no need for a rear bushing.
Component part number XTN-00027 is the bushing for arrows of .244” ID
Component part number XTN-00028 is the bushing for arrows of .246” ID

Bloodhound XTN Operating Instructions

Crossbow bolts with 285”, .297”, and .300” inside diameters, in addition to a front bushing as in the
above, require a second bushing on the rear of the battery holder shaft for snug fit with the bolt.
Component part number XTN-00029 is the front bushing for bolts of .285” ID
Component part number XTN-00030 is the front bushing for bolts of .297” ID
Component part number XTN-00031 is the front bushing for bolts of .300” ID
Component part number XTN-00032 is the rear bushing for bolts of .285” ID
Component part number XTN-00033 is the rear bushing for bolts of .297” ID
Component part number XTN-00034 is the rear bushing for bolts of .300” ID
Install the same size and number of bushings onto the practice XTNs as you did the live XTN tracking
nock. The fit to the shaft should be snug, where the XTN can be inserted into shaft without a tool, but
stay completely in the shaft when hanging from rear of pin nock end and slightly shaking the arrow /
bolt. Install completely so the rear of the arrow / bolt lands onto the aluminum ring in the front of the
XTN wings. Not following this could result in personal injury and/or damage to your equipment.
3) Pin Nocks.
Next, install the proper nock to fit the weapon being used. In case of compound bow, use the pin nock
included. In case of crossbow bolt use the included flat, half moon, or capture nock style as described
by the crossbow manufacturer.
Compound bow:
Component part number XTN-05001 pin nock
1. While rotating, press the pin nock onto the pin bushing until it is fully seated against
the base of the pin bushing.
2. Rotate the XTN wings according to preference and arrow rest design.
3. Rotate the pin nock to index it according to preference and arrow rest design. Be
sure not to rotate the wing from the prior arranged position.

Crossbow:
Component part number XTN-00007 flat pin nock
Component part number XTN-00008 half-moon pin nock
Component part number XTN-00009 capture pin nock
1. While rotating, press the pin nock onto the pin bushing until it is fully seated against
the base of the pin bushing.
2. Rotate the XTN wings so they are perpendicular to the index vane (odd colored
vane) of the bolt so the XTN wings float across (horizontal) the rail of the crossbow.
3. Rotate the pin nock to index it to the crossbow string and XTN wings. Be sure not to
rotate the wings from the prior arranged position.
CAUTION!
- Please note: pin nocks included in your kit are designed for use with their corresponding
weapon as described above. Do NOT use the designated compound bow pin nock in crossbows.
Crossbows increased acceleration requires the more robust designated crossbow pin nocks. Use
of the compound bow pin nock in a crossbow may result in personal injury and/or equipment
damage.
- Do NOT use this product if the XTN wing rear outside corners come in contact to the crossbow
string when the crossbow is cocked. If the nock wings touch the string this may result in
personal injury and/or equipment damage during firing of the crossbow.
- Do NOT glue pin nocks onto the pin bushing. Doing so may weaken the pin nock and result in
personal injury and/or equipment damage.
- Inspect pin nocks before EACH shot. Cracked, chipped, or loose-fitting pin nocks should be
discarded and replaced immediately. Failure to inspect and replace may result in personal injury
and/or equipment damage.
- Make sure usage of this product DOES NOT inactivate your crossbows anti dry fire feature (if
equipped with an anti-dry fire feature).
4) Activation.
WARNING! Seek expert advice for proper setup before using. Bow cables, cable rollers, bow riser,
arrow rest, and bow site clearance by the XTN tracking nock wings is required! If the XNT tracking
nock wings do not clear their entire travel path before exiting the front of the bow it may result in
personal injury and / or equipment damage.
The XTN Tracking Nock will automatically activate upon arrow / bolt launch because of the force that
activates a proprietary inertial switch built into the XTN. Upon string release two LED lights will light up
in the rear of the wings for 3 seconds letting you know the XTN is on and aiding you in seeing the flight

Note:
As with any sporting equipment, i

follow all of the instructions provided with your Bloodhound XTN system.
Particularly those pertaining to the mounting and use of the tracking nocks with
your particular equipment and setup. Failure to do so may result in personal injury.
of the arrow / bolt. After 3 seconds the XTN will go into a blinking mode where it will stay on and
transmit for as long as 18 hours. The tracking nock does not need to be turned off to be shot again and
reactivated (initial 3 seconds of lighted LEDs), as it will reactivate each time it is shot.
5) Turning the XTN tracking nock from activated to standby mode.
Hold the Magnet Tools magnet end within a half inch of the XTN tracking nock shaft where the arrow /
bolt shaft and front of wings cross. Either side of XTN, top or bottom when arrow lays horizontal will
work, as long as you are near the front of the wings. Do this for two seconds. The LED lights will
immediately stop flashing when changed to standby mode. XTN tracking nock can now be shot again,
recharged, or stored.

Functions of the XTN Tracking Nocks
Battery status. To see the state of charge, plug the XTN tracking nock into the charger. The LED’s will
flash from 1 to 4 times to indicate the charge level. The chart below shows the levels for each of the 4
zones. 4 flashes is 74% capacity or more, 3 is 49-74%, 2 is 19 to 49%, 1 flash is below 19%. Note that 1
flash is anything below 19%, and could be as low as 1%. Our recommendation is to ensure that you have
4 flashes before going on a hunt. The XTN can be left in the charger to view the state of charge
indication or pushed in and pulled out quickly. Once the state of charge is shown the XTN returns to
standby mode.
Test mode. With the XTN inserted into an arrow / bolt shaft, hold the magnet near the end of the arrow
/ bolt shaft or just in front of the XTN wings, and plug the charger onto the XTN (or push the XTN into
the charger). The LED’s will light immediately and stay on for as long as the magnet is held in place.
Upon removing the magnet, the battery status flashes will be shown followed by the 3 second flash as if
the XTN was just launched. Once the 3-seond interval is over the transmit operation will be started and
the LED’s will give a short flash once every 1.4 seconds. Test mode can be stopped by applying the
magnet for two seconds as described above. The XTN will then return to standby mode.
Storage mode. Storage mode is entered into the same way as test mode except the magnet is left in
place for 20 seconds. At the end of the 20 second interval the XTN will flash the LED’s very rapidly for
about 2 seconds and will enter storage mode. When in storage mode, the XTN cannot be activated by
launching or handling the unit. To exit storage mode the XTN must be inserted into the charger at least
for a moment. If the state of charge flashes are seen then you know that the XTN has returned to
standby mode.
Standby mode. XTN is in low power standby waiting for the inertial switch to be activated or for the
charging voltage to be applied. If the switch is activated, the LED’s will immediately come on for 3
seconds and then the transmission sequence will start. Transmit is retriggerable; if transmit mode is

already active, launching the XTN again will repeat the 3-second LED flash and resume transmissions
again. Note that it is not transmitting during the 3-second interval. The Tracker will probably lose sync
with the XTN if it is tracking the XTN during a second launch. If scanning, the tracker will pick up the XTN
in the scan as soon as it starts transmitting again, and if tracking it will automatically reacquire the XTN
4-5 seconds after transmissions resume. When stopping transmit with the magnet, the XTN will go back
to standby mode.
Your Tracker has two different operating modes:
Scan
The scan operation sweeps the surrounding area for any (up to 6) tracking nocks that are currently
transmitting and shows them on the Tracker’s display. If more than one tracking nock is found to be
active then the display will show which tracking nock has the highest signal level, indicating that it is
likely to be the closest one to you.
Scan is used when you are uncertain which tracking nock(s) have been shot or, if several shots have
been taken, which tracking nock is closest to you for recovery. Once you have found and deactivated the
tracking nocks from missed shots and determined which tracking nock is on the arrowed game, the
tracking mode can be used for recovery.
Track
The tracking operation searches for the radio signal from the selected tracking nock and, once found,
displays a directional arrow and signal strength indication. The signal strength indication is always
available when the tracking nock is within range and can be used to search in a “hotter/colder” fashion
to get closer to the game. The directional arrow will help guide you to the exact location of the game, or
missed shot, when you get closer to the tracking nock.

System Operation
Controls
The Bloodhound XTN Tracker has a power button and 6 control buttons as shown above.
Control Functions:
 Power: The power button is pressed for 3 seconds to toggle the Tracker on and off
 Track: Enters track mode
 Scan: Enters scan mode
 Stop: Stops either tracking or scanning
 Sounds: Toggles the internal beeper on and off (sound is helpful during tracking)
 Select: Used to select the highlighted item on the display
 Backlight: Toggles the display backlights on and off (this is helpful during low light tracking)
Charging the Tracker
Charging is accomplished by connecting the supplied AC adapter and Micro USB cable to the Power jack
on the front panel of the Tracker as shown below.
The Tracker will charge whether it is turned on or off. Charging a fully discharged battery takes 2 ½ to 3
hours. If you turn the Tracker on while charging, the gage (shown under “Powering on the Tracker”
below) will count up repetitively to show that the Tracker is charging, when done charging, the gage
stops counting up and shows full. If the charger is kept plugged in with the Tracker on, eventually the
battery will need to be “topped-off” and the gage will show charging status again until the battery is
back to 100% charge capacity.
The Tracker can be charged with the supplied AC adapter and also any USB power source that can
supply 1 amp or more of current. This can include other USB AC adapters, a charging outlet in a vehicle,
a USB port on a computer, a rechargeable USB battery or any other USB source with the required
current capacity.

Powering on the Tracker
To power on the Tracker, hold the round power button down for 2-3 seconds until the display comes on.
Initially the display will show all available icons and then will present the idle display as shown below.
The Tracker’s battery gage is always shown and indicates the state of charge of the battery. There are 5
levels that can be shown; 4 bars is the highest charge level and no bars showing is the lowest level.
Scan Mode
If you are uncertain which tracking nock numbers you have shot and wish to track, Scan mode allows
you to determine which tracking nocks are currently transmitting within the range of the Tracker. This
may be used for gathering missed shots or for tracking an animal if the nock number is unknown.
To start Scanning for active tracking nocks, press and release the Scan button. The display will appear as
shown below.
The scanning process starts with tracking nock type 1, after 3 seconds the Tracker will display the results
for number 1 and begin searching for number 2. This process will continue through all 6 types and then
begin with 1 again until either the Stop button or Track button is pressed.

As the scan progresses, each activated nock type found to be within range will have its number
displayed on the screen. If more than one tracking nock is found, then an up-arrow will indicate which
one has the highest signal level and therefore is likely to be the closest one to your location. Note that
an arrow that is, for example, buried in the snow, close to you and one that is stuck in a tree further
away may show the one in the tree as being the closest because of the signal lost passing through the
snow.
The screen below shows an example of the scan operation starting a second pass with tracking nocks 1,
3 and 5 already found to be within range and number 3 having the highest signal level. The Tracker is
currently scanning for tracking nock type 2. If a tracking nock number that was previously found is no
longer responding, perhaps because you, or it, has moved out of range, then the number will be cleared
from the display after that type is searched for again. The display refreshes 3 times per minute so it
always reflects the current status of the tracking nocks within range of your location. If you are
searching with the aid of a moving vehicle, it is best to drive no more than 15-20 MPH so you are not
driving through the area covered by the Tracker before a scan completes. If the sounds are enabled you
can use the Tracker for hands-free searching by listening for the beep tones. Each time the Tracker
receives a signal from an XTN there will be an audible indication from the Tracker.
Pressing the Stop button clears the scan display back to the idle screen (as shown in “Powering on the
Tracker” above). Once you know which tracking nocks are within range you may select one for tracking.
Track Mode
There are two ways to enter Track mode, one is from the idle mode, such as when the Tracker is just
powered on, and the other is from the Scan mode. Either method starts with pressing the Track button.
If entering Track mode from the idle mode, the Tracker’s display will appear as shown below. All 6
tracking nock types will be shown with the cursor on the number 1 position. Each press of the Track
button will advance the cursor to the next number. When the cursor is over the desired number you can
press select (Sel button), or wait 3 seconds without pressing track, to lock in the selection. If you

accidentally pass over the desired number, then you can continue pressing track and rotate through all
the available numbers again.
If entering the track mode from the Scan mode, the process is the same as shown above but the results
of the scan operation will be shown on the display. This allows you to easily select a tracking nock that is
currently active and within range and, if desired, to select the one that has the highest signal level and is
likely to be the closest to your location. You do not have to select a tracking nock that was found in the
Scan mode, you can track any of the 6 nock numbers even if they were not found in the Scan operation.
Whether starting from Idle or Scan, once a tracking nock number is selected, the tracking display will
appear as shown below. In this example, tracking nock number 2 was selected for tracking.
If the tracking nock is nearby, the Searching operation will take about 3 seconds to complete and then
the Tracker’s screen will move to the track mode as shown below. Often, the tracking nock will be out of
range and you will need to move closer to pick up the signal. Do not be concerned about switching off
the Tracker to conserve power for extended searches, the Tracker can stay in search mode for a full 24
hours on a fully charged battery, even with the display backlights switched on.

Once the tracking nock is within range, the Searching indication will disappear, and the Tracker’s display
will appear as shown below. Once tracking is started, the display will be updated once every 1.5
seconds.
Signal Strength: The signal strength indication will always be present on the screen as long as the
tracking nock remains within range of the Tracker. This can be used in a “hotter/colder” fashion to get
closer to the tracking nock and to know if the nock is a great distance away or very close by.
The signal strength varies from 0% (no signal) to 99% (maximum signal). In practice, you will generally
not see a 0% reading on the display because it takes some signal for the information from the tracking
nock to be received, 8% - 10% is usually the lowest you will see and indicates that the nock is barely in
reception range. 99% is the highest signal level that can be measured and indicates that the tracking
nock is very close, within a matter of feet, of your location.
Signal strength is shown as a percentage varying from 0 to 99% but it is not strictly a percentage. 50% is
not half the range of the system and 25% is not necessarily twice the distance away as 50%. In general,
each 14% increase in signal strength indicates that you are now half the distance from the tracking nock
than you were before. Please refer to the Tracking Tips section for further pointers on using the signal
strength indicator.

Directional Arrow: Each time a signal is received from the tracking nock the Tracker attempts to
measure the direction that the signal arrived from. If the direction cannot be measured because of
signal reflections, obstructions or insufficient signal level, then the directional arrow will not be shown.
The directional arrow is useful for heading in the general direction of the nock and to precisely locate
hidden game or missed shots. There are many factors that can influence the directional arrow
indication, please refer to the Tracking Tips section for further pointers on using the directional
indicator.
Tracking Nock Battery Status: The nocks battery status display has 4 levels; 4 bars indicates a battery
that has a 75% to 100% state of charge and 1 bar indicates a battery that has less than 20% remaining
capacity.
No Signal: If you are tracking a nock and the signal is lost for a period of time then the display will read
“No Signal” and no signal strength, directional indication or tracking nock battery status will be shown. If
the no signal condition persists then the Tracker will return to the searching mode for the selected
tracking nock and you will need to move back into range for the tracking operation to resume.
Tracking Tips: If you are in an open area with few obstructions and the tracking nock is within range of
the tracker then tracking is easy – just start the Tracking mode and follow the arrow directly to the tracking
nock, if you are not careful you may step on it. However, if you are in rough terrain the radio signals lose
their power much more quickly and are blocked by objects while being reflected off others. In situations
like this, you need to use some techniques to get the most out of the Bloodhound XTN system. Here are
some tips on tracking that will help you track more effectively:
1. Begin the search using the techniques that you normally use (i.e. observing the direction of the
game, following the blood trail, etc.) If you know the tracking nock number you are searching for
then use Track mode as it gives a faster indication that you are within range. If you are not certain
about the nock number, then use the Scan mode until you come within range.
2. If you are using Scan mode, then switch to Track once the tracking nock number is known.
3. Once the communications with the tracking nock have begun (Searching is no longer displayed,
dog’s tail is wagging and the information on the display is updating) use the directional display to
determine in which general direction to proceed. If you cannot get a directional arrow, or it is erratic,
take the following steps:
a. Make certain you are holding the Tracker in front of you, waist high and screen facing upward.
b. If possible, move to a clear, unobstructed area away from buildings, automobiles, hills, etc.
c. Higher ground is always better if available, even the standing on the bed of a truck or on a boulder
will improve both the range and the direction finding.
d. If you do not get a directional reading facing one direction, turn 90 degrees and try again. Once
you get a directional arrow, always turn to face directly in that direction, with the arrow straight
ahead. Walking away from the tracking nock will not produce good results.
e. If you are still not getting a directional indication it is often possible to use the signal strength
indicator to resolve a general direction to head in. Hold the handle of the Tracker in tight to your
body and note the signal strength reading, now turn 90 degrees and note the reading again. Do
this in all 4 directions and then head in the direction giving you the highest reading.
f. When you first get a directional indication, it is best to qualify it to make certain that you are
moving towards the tracking nock and not away from it. To do this, turn your body so that the

and, whenever possible, have a companion with you to operate the Tracker.
arrow points straight ahead, now turn 90 degrees and check to see if the arrow still points in the
same general direction. If it does, then that direction is likely to be correct. If the arrow now
points in the opposite direction of what it did originally, turn your body to face that direction, if
the arrow confirms that direction then it is likely the correct path to the tracking nock.
g. Always note the signal strength indication as you move, if you lose signal or if it becomes
significantly lower, return to the area where you had higher readings and then choose a different
direction to search.
h. When far away from the nock the directional arrows will show the general path to take to get
closer (e.g. up the trail vs. down the trail). If the nock is far away you know that its direction from
your location can not change quickly, so don’t try to gauge each step based on the directional
arrow, just move along until you see a consistent change in the indicated direction. Verify that
the signal strength is generally increasing as you move forward. Once again, the signal strength
will vary somewhat with each reading, you want to look for a trend in the readings are generally
getting higher or lower as you move.
i. When you are close to the nock, the directional information will become much more sensitive.
For example, if the nock was in a bush just to the right of the path you are walking on you might
see the arrow point forward as you approach. Then, a few seconds later, the next reading may
point directly to the right because you are now next to the bush. If you take one more step, a few
seconds later the directional arrow would be pointing behind you because you have now passed
the bush. In contrast, if you were 100 yards from the tracking nock then a few steps in any
direction will not change the directional indication because the change is so small.
j. If searching from a vehicle, you will be primarily be looking to establish contact with the tracking
nock and then leaving the vehicle to continue to search on foot.
Exiting Scan or Track Modes
You can stop Scan or Track mode and return to the idle screen at any time by pressing the Stop button.
Alternatively, if you are finished using the Tracker you can simply turn it off to exit either mode.
Scan Setup
By default, the Tracker scans all 6 tracking nock types to determine which nock numbers are
transmitting within range. If you do not have all 6 nock types or are using only certain ones on a hunt,

Bloodhound XTN Operating Instructions
16
it is beneficial, but not essential, to disable the search for tracking nocks that you do not own or have
not shot.
To enter Scan Setup mode, hold the Sel button down until the display shows Setup (about 3-4 seconds)
and then release the Sel button. The Tracker’s display will appear as shown below.
When entering Scan Setup for the first time, all 6 nock numbers will be shown. Short presses of the
select button will move the cursor to the next nock number. To include a nock number in the scan, place
the cursor on that number and press the Scan button. To remove a nock number from the scan, place
the cursor on that number and press Stop. If you pass over a nock number that you wish to change, you
can move through the selections again with short presses of the Sel button. Once you have the desired
list of tracking nocks that you wish to include in the scan, press and hold Sel for 3-4 seconds until Setup
disappears from the display.
If you have been using the Scan Setup feature to configure the tracker for different hunts, practice
sessions, etc., then you should check the setups prior to using Scan mode to make certain it is
configured correctly for your current situation. You may also verify that the Tracker is searching for the
correct nock numbers by noting which numbers are included when scanning and which are skipped
over.
SAFETY INFORMATION
ARROW REST WARNING: Before shooting any Kirsch tracking nocks it is extremely important to inspect
the arrow rest to ensure that it is a proper choice and properly adjusted to clear the diameter and width
of the tracking nock being used. FAILURE TO PROPERLY SELECT AND ADJUST THE ARROW REST TO
CLEAR THE TRACKING NOCK WINGS SIGNIFICANTLY INCREASES THE RISK OF INJURY TO THE SHOOTER
AND DAMAGE TO THE EQUIPMENT. Incorrect selection and adjustment of the arrow rest may cause the
tracking nock to collide with the arrow rest and/or get jammed in the bow which could result in injury to
the shooter or bystanders, and damage to the shooting equipment. ALWAYS MAKE CERTAIN THAT THE
ARROW REST IS PROPERLY SELECTED AND ADJUSTED BY A QUALIFIED INDIVIDUAL BEFORE SHOOTING.
Scan Setup

Bloodhound XTN Operating Instructions

Selecting the correct arrow length is the responsibility of the shooter and failure to do so could result in
severe injury, and/or damage to shooting equipment.
TRACKING NOCK INSPECTION WARNING: INSPECT EACH ARROW AND TRACKING NOCK FOR DAMAGE
PRIOR TO EVERY SHOT. Proper care can ensure years of quality performance. However, shafts and
nocks can be damaged. To inspect a nock closely examine for any cracks, change in shape, or pieces
missing from the nock. Rotate and repeat this inspection process four to five times around the entire
circumference of the nock. If you find any nock to be damaged in any way discard it immediately.
SHOOTING DAMAGED NOCKS CAN RESULT IN NOCK FAILURE AND PERSONAL INJURY.

of any kind arising out of the purchase or use of any product, whether based on contract, tort, statue or
