Important Safety Info
GENERAL SAFETY WARNING
Only operate your DCI guidance system in accordance with the
operating instructions for your system.
Serious injury and death, as well as property damage, can result if
underground drilling equipment strikes a natural gas line, high-voltage
electrical cable, or other utility.
Work slowdowns and cost overruns can occur if you do not use your
system correctly.
You must properly calibrate your DCI guidance system in connection
with each drilling project. If you fail to do so, depth readings will likely be
inaccurate.
Interference can lead to inaccurate depth readings and/or interruption
of data. See "Special Notes About Interference" for more details.
DCI guidance systems are used to locate and guide the transmitter
(housing) underground. They cannot be used to locate underground
utilities.
Failure to fi nd the front and rear locate points can lead to inaccuracies
which may result in drilling o ff -path and striking an underground utility.
The locate line on a DCI locator does not indicate the position of the drill
head. DCI locators track the transmitter in its housing, which sits behind
the drill bit. Also, when drilling steep and/or deep, the locate line may
indicate a position behind or ahead of the transmitter. Please see "Steep
and Deep" under Advanced Topics for important information about
accurately locating the drill head when drilling steep and/or deep.

Ensure that all underground utilities have been located, exposed, and/or
accurately marked prior to drilling. Follow all proper safety precautions,
such as potholing.
DCI equipment is not explosion-proof and should never be used near
fl ammable or explosive substances.
Wear jobsite protective/safety clothing such as dielectric boots, gloves,
hard hat, high-visibility vest, and safety glasses.
Maintain a minimum distance of 8 inches (20 cm) from the front of the
locator to the user ’ s torso to ensure compliance with RF exposure
requirements.
Comply with federal, state, and local governmental regulations (such as
OSHA) and all other customary or required safety precautions.
If you have any questions about the operation of your guidance system,
please contact DCI Customer Service for assistance.
SPECIAL NOTES ABOUT INTERFERENCE
While DCI guidance systems provide you with technology to combat active
interference (and passive interference, with the Sub-K Rebar transmitter),
no guidance system is immune to all interference.
Interference can lead to inaccurate depth readings and/or interruption or
loss of data. Never rely on data that does not display quickly and/or remain
stable.
The Falcon frequency optimizer selects frequencies based on measured
interference at a speci fi c time and location.
Interference levels change with time and with even minor changes in
location. The frequency optimizer is not a substitute for prudent operator
judgment. If performance drops while drilling, consider switching to the
other selected band (not available on the Falcon F  ) or use Max Mode.

An A on the screen can indicate signal Attenuation due to the presence of
excessive interference, which can make depth readings inaccurate.
Attenuation is normal in shallow depths less than 8 ft (2.4 m). If the signal
strength is also fl ashing; this indicates extreme interference. Depth and
locate points may be compromised and the locator will not calibrate.
Interference is classi fi ed as either active (generating electro-magnetic
signals) or passive (material that can conduct or block electro-magnetic
signals). Sources of interference may include:
Active
Tra ffi c signal loops
Buried dog fences
Cathodic protection
Radio communications
Security systems
Microwave towers
Power, phone, fi ber-trace and cable TV lines
Passive
Metal pipes
Rebar
Trench plates
Chain-link fences
Vehicles
Saltwater/salt domes
Conductive earth, such as iron ore

HDD LOCATING HISTORY
Locating in the horizontal directional drilling (HDD) industry was initially
based on locating a buried cable by sweeping the locator back and forth to
fi nd the highest signal strength (peak signal), indicating that the locator was
over the cable. Unfortunately, this method did not always guarantee an
accurate location of the cable, nor did it provide any depth information.
This “ peak signal ” method was adapted to HDD with the introduction of a
transmitter that provides information on the position and depth of the drill
head. However, this method is unreliable and inaccurate because the peak
signal strength is not always directly above the transmitter housing.
In addition, peak signal locating doesn ’ t show where the drill tool is headed.
Think of drilling like driving a car: it is more e ff ective to look ahead through
the windshield to see where you are going than to look down at the road
through the fl oorboard to keep the car (drill tool) on the road (drill path).
BALL-IN-THE-BOX GUIDANCE
DCI ’ s design uses a “ locate point ” in the transmitter signal. The Front Locate
Point (FLP), which is out ahead of the transmitter, shows where the
transmitter housing is heading.
DCI invented the Ball-in-the-Box user interface to make it quick and intuitive
to fi nd a locate point, speeding up drilling jobs: just move the locator so the
ball moves into the box on the screen.
Finding a locate point also helps you fi nd the drill head itself.

FALCON F  SUB-K REBAR USER MANUAL
DCI DigiGuide 07.08.2022

There is a second locate point behind the transmitter called the Rear Locate
Point (RLP). The two locate points, combined with a Locate Line (LL),
pinpoint the precise location of the transmitter housing below ground.
They are arranged like an airplane, where the Front Locate Point is the
plane ’ s cockpit, the Rear Locate Point is the tail, and the Locate Line is the
wings.
If your drill path requires a certain amount of depth or to maintain a
constant pitch, use the predicted depth feature at the Front Locate Point.
This eliminates the need for depth readings over the transmitter, speeding
up the drilling process.
INTERFERENCE AND SIGNAL STABILITY
Interference can cause incorrect locate data that reduces locating
accuracy. There are two di ff erent types of interference that can distort the
transmitter signal: active and passive.
Active interference, or “ noise ” , consists of anything that emits a signal that
interferes with the transmitter signal. Example sources include power lines,
radio towers, cathodic protection, fi ber tracer lines, invisible dog fences,
security systems, and tra ffi c signal loops. Falcon ’ s frequency optimizer fi nds
the best frequencies to avoid noise.

FALCON F  SUB-K REBAR USER MANUAL
DCI DigiGuide 07.08.2022
DIGITAL CONTROL, INC 8
Passive interference consists of anything that blocks or distorts the
transmitter signal resulting in incorrect depths or missing data. Example
sources include rebar, guard rails, bridge abutments, chain link fencing,
salt/saltwater and soil high in metal ore. The Falcon sub-kHz transmitter
(available for Falcon F  and F  + only) helps cut through passive interference
without distorting the signal.
An A on the screen can indicate signal Attenuation due to the presence of
excessive interference, which can make depth readings inaccurate.
Attenuation is normal in shallow depths less than 8 feet (2.4 m). If the signal
strength is also fl ashing, this indicates extreme interference. Depth and
locate points may be compromised and the locator will not calibrate.
OPTIMIZE EVERY JOB
Noise varies by amount and frequency depending on where you are and
even the time of day. That ’ s why it ’ s important to fi nd the best frequencies
for every bore .
This is called frequency optimization , and only Falcon has it. Using
frequencies with the highest probability of success against noise increases
locating accuracy and reduces the risk of tripping out.
Falcon ’ s frequency optimizer scans through hundreds of frequencies, then
bundles those with the lowest noise into fi nely-tuned bands that work best
for the current job.
Select two bands and switch between them mid-bore if needed (not
available on the Falcon F  with singleband).
The Falcon locators with Quick Scan Pair o ff er features to make the selection
of bands faster and easier. Two clicks select the two preset bands selected
for your region.

MENU NAVIGATION
The Falcon F  /F  /F  +/F  + has a toggle switch on top and a trigger switch
under the handle to navigate the menu system and select options.
Use the  -way toggle switch to access a menu, move between menu options,
and open shortcuts.
Shortcuts require you to hold the toggle for a second or longer; we call this a
“ hold toggle ” . For example, from the Locate Mode screen, open a transmitter
band selection shortcut by holding the toggle right.
Use the trigger switch to power on the locator, select a menu option, and to
take a depth reading.
Pull and release (click) the trigger to select. In some cases, you ’ ll need to
hold the trigger for a second or more to use a function, such as turning the
locator on or taking a depth reading.
BENEFITS OF DATALOGGING
Utilities increasingly require a digital as-built report to ensure drilling
parameters were met.
The DataLog® feature on your locator lets you easily capture and store the
rod-by-rod data of your pilot bore.
When used with DCI ’ s LWD Mobile app, geo-tagging the entry and exit
automatically ties the as-built to a physical location.
