______________________________________c
Power on/off:
Power On: Quick-Press (press-and-release button)
• Hear start-jingle followed by ready-beep.
• Wait for ready-beep before presenting pinpointer to metal.
If metal is near pinpointer before ready-beep, pinpointer will
overload (not detect) or operate at reduced sensitivity (see
Overload p.8) .
Power Off: Press-and-Hold the button for 1/2 second.
• Release the button when
you hear the power-down jingle.
Proportional Target Alert
As the F-Pulse approaches a target, the audible alert intensies.
The closer you get to the target, the faster the beep.
Retune
With the pinpointer ON, quick-press the button to retune.
The sensitivity level will generally not change or drift, but
certain operating conditions may cause a loss of sensitivity or
spontaneous alert (excess sensitivity).
Keep away from metal when retuning with quick-press.
LED Flashlight:
1. Start with power OFF.
2. Press-and-hold button for 1 second.
• LED status will change (on-to-off or off-to-on).
3. Release button.
4. Device is powered ON; ready to hunt.
Default Settings
• LED, On
• Alarm, beep+vibrate
• Sensitivity, medium

d____________________________________
Programming Alarm and Sensitivityitivity:
1. Start with power ON.
2. Press-and-hold button. Do not release the button at the
rst alarm (power-down-jingle).
3. Following the power-down-jingle:
• Wait 2 seconds
• Hear the program-menu-jingle
• Immediately release button
4. You are now in the Programming Menu.
5. In the Programming Menu:
• Pinpointer will not detect metal
• LED will ash continually, once per second, to indicate
you are in the Programming Menu
• Quick-press to advance to next setting
• Press-and-hold to:
a) save setting
b) turn Pinpointer off.
There are 6 settings to choose from:
SENSITIVITY LEVEL TARGET ALERT
1. Low Beep + Vibrate
2. Medium Beep + Vibrate
3. High Beep + Vibrate
4. Low Vibrate only
5. Medium Vibrate only
6. High Vibrate only
Note: If target-alert set to vibrate-only, there will be no
beep at power-on or power-off.

Ground Cancelation
In mineralized soils, you may need to cancel out the
signal from minerals in the soil. There are two methods,
depending on the type of ground mineralization.
For Saltwater and Most Ground Mineralization Conditions
1. Start with power on.
2. Touch the tip of the probe to the soil, or submerge into
the water.
3. Quick-press the button.
4. Hear beep, conrming calibration is complete.
For Extreme Ground Mineralization
If pinpointer beeps erratically or “falses” when it touches
the ground, even after performing the Ground Cancelation
procedure above, cancel ground by powering pinpointer on
after touching shaft to the ground.
Alternate Calibration Procedure:
1. Start with power OFF.
2. Touch the tip of the probe to the soil.
3. Quickly press-and-release the button to turn power ON.
4. Pinpointer is silent and ready to detect.
Caution: If you turn on the F-Pulse in close proximity to a
metal target in the ground, you may desensitize it, or put it
into overload. If using this alternate ground calibration method,
be sure to touch the tip to the ground away from your target.

f____________________________________
Interference (Frequency Shifting)
All metal detectors operate at different frequencies. It’s these
different frequencies that make certain detectors better at
detecting certain targets. The F-Pulse is designed to work with
the different frequencies of various detectors, and to enable the
user to calibrate the F-Pulse to a frequency that eliminates (or
minimizes) interference with your detector.
The factory default setting of the F-Pulse may interfere with your
metal detector, causing it or your pinpointer to beep irregularly.
A pinpointer is most
likely to interfere
with your metal
detector when
pointed into the
horizontal plane of
the searchcoil.
To minimize
interference while
probing the ground,
lay the metal
detector down
with the searchcoil
perpendicular to
the ground.

___________________________________g
Frequency Shift: (To eliminate interference with your detector)
1. Turn Pinpointer power OFF.
2. Turn your detector ON.
3. Turn Pinpointer ON.
4. Press-and-hold button for 4.5 seconds
to reach Frequency-Shift menu as follows:
a) Hold for 1/2 second and hear power-down jingle.
• Continue to hold.
b) Hold for additional 2 seconds and hear
program-menu-jingle.
• Continue to hold.
c) Hold for additional 2 seconds and hear
frequency-menu-jingle.
• Release the button.
5. While in Frequency-Shift menu:
• The Pinpointer will detect metal.
• LED will ash continually, twice per second.
6. Quick-press button to cycle to next frequency.
• There are 16 different frequencies to choose from.
• Hear an increasing pitch as you change frequency.
• When pitch changes from high to low, you have
cycled back to the rst frequency selection.
7. Stop at the frequency that does not interfere with your
detector.
8. Press-and-hold button for 1 second to turn off.
• Your frequency selection is saved.
• Quick-press to power-on and continue detecting.

h____________________________________
Overload
The F-Pulse must not be near metal during power-on
(approximately one second). If you power it on in close
proximity to a metal object, it will enter Overload Mode.
If in Overload Mode, the following will happen:
1. Hear audio alert: BEE-BOO BEE-BOO BEE-BOO.
2. LED light ashes continuously.
3. Pinpointer will not detect metal.
To exit Overload Mode:
1. Move it away from metal.
2. Quickly press-and-release the button.
3. Pinpointer will alarm and LED stops ashing.
4. Ready to detect.
Re-Boot
If your pinpointer becomes unresponsive and/or locks up, and
any sequence of button presses does not return it to normal
operation, it’s time to re-boot.
1. Remove the battery door to break battery contact.
2. Replace battery door and resume operation.
Lost Mode and Auto Shutoff
If the F-Pulse is left powered on with no button presses for 10
minutes, it will enter Lost Mode. The unit enters a low-power
setting, the LED ashes and the unit beeps every 15 seconds.
After 30 minutes, the unit will completely power down.

___________________________________i
Batteries
The F-Pulse operates on 2 AA alkaline, lithium or nickel-metal
hydride batteries (not included).You can use high quality
rechargeable batteries. Expect approximately 25 hours of
operation from alkaline batteries.
Do not use “Zinc-Carbon” or “Heavy-Duty” batteries.
To replace batteries:
1. Use a coin or athead screwdriver.
2. Rotate counterclockwise to remove cap.
3. Install 2 AA batteries, positive-side down.
4. Rotate clockwise until snug to close and seal.
The battery compartment was designed to provide a snug t
for the batteries. If you experience difculty in removing your
batteries, tap the pinpointer against the palm of your hand to
help dislodge the batteries.
CAUTION: Waterproong requires a tight seal.
Rotate battery door securely for waterproof seal.
Low-Battery Warning:
If your batteries are running low and need to be replaced,
you will hear a boop-boop-boop sound at power-down.
Critical Low-Battery:
If the batteries are totally spent, you’ll hear a boooooop
sound and the pinpointer will then turn itself off.

j____________________________________
Waterproof Design
The F-Pulse is waterproof to a depth of 6 feet for 1 hour.
The rubber O-ring around the battery cap is vital to maintaining
a waterproof seal.
You must periodically apply a silicon spray lubricant
to the o-ring to maintain a watertight seal.
IMPORTANT:
Check the O-ring.
Make sure there is no debris on the O-ring or in the battery
cap threads.
WARNING:
Submersing this
product to a depth
greater than 6 feet
and/or longer than
1 hour will void
warranty.
