Quick Start
Use your F75 right out of the box
1. Assemble the detector (see instructions beginning page 4).
2 Install four AAalkalinebatteries. All positive (button-end) terminals point up.
Batteries are included with the detector.
3. Turn the knob, located under the armrest, fully clockwise.
This turns the machine on and sets audio volume to maximum.
4. When first turned on, the F75starts out in the Discrimination mode, with:
Sensitivity preset to 60
Discrimination Level preset to 10
Number of Tones preset to 3
Process# preset to dE
Sweep the searchcoil from side to side, parallel to the ground. Keep the searchcoil
moving over the ground. If you stop moving the searchcoil, the sound will also stop.
Probable target type will be indicated at the top of the LCD screen.
5. If the searchcoil is not in motion and not close to metal, the detector should be
silent.
6. If you experience false signals from electrical interference, from the soil itself, or
from lots of trash metal, press the MENU button.
Sensitivity will be highlighted.
Rotate the Settings knob to the left (counterclockwise),
Reduce the sensitivity setting until the false signals go away.
After 7 seconds, the machine will exit the menu and return to
normal operation.
7. Find a patch of ground free of metal, toss a coin on the ground and sweep back and forth
over it a few times to get a feel for how the machine responds.
8. You are now ready to search.
9. Pull and hold the trigger switch with your index finger to pinpoint the exact location of
targets, making them easier to unearth.
When the trigger is pulled, PinPoint is engaged ….
The searchcoil need not be in motion to detect an object.
The 2-digit numeric display indicates approximate target depth, in inches.

Assembly
1. Remove all components from box.
2. Attach searchcoilto lower rod by
lining up the holes.
Push coil knob through hole
and tighten knob gently.
You will tighten up the coil knob later.
3. Insert smallest rod into S-rod
(S-rod holds detector body).
Turn top locking collar
counter-clockwise to open up.
Push in pin on small rod.
Slide small rod into upper rod.
Click pin into hole and tighten
locking collar firmly clockwise.
4. Pushlower rod into small rod
as follows:
Turn locking collar
counterclockwise to open up.
If plastic insert tab interferes,
push it down, or turn tube upside down.
Push in pin to allow rod to slide in.
Slide lower rod in.
Click pin into any hole.
5. Remove velcro stripfrom lower rod.
6. Wrap cable around stem as follows:
Leave some slack in cable at
base of lower rod.
Secure cable at base of rod with velcro strip.
Wrap cable loosely around entire
stem up to bent part of upper rod.
You will re-wrap the cable later
after
