Control housing
Shortened stem length
Extra, coiled
cable
1. Adjust the stem length and coil angle so the search
coil rests flat on the ground about 6 inches in front
and slightly to the right of your foot (to the left of
your left foot if you’re left handed).
2. Leave enough slack in the coil cable to allow the
coil to swivel as far as it can in either direction. The
coil wing nut should be tight enough to prevent
the coil from moving.
3. You should now be able to move into your “search”
position by leaning slightly forward and raising the
search coil no more than 2 inches above the
ground. Your arm should still be straight, and the
coil should be parallel to the ground, about 12
inches in front of your foot. The coil angle may have
to be slightly readjusted at this point.
SETTING UP FOR DIVING
Unlike most VLF metal detectors, the CZ-20 works well in salt
water. This capability, along with its deep-seeking sensitivity,
makes it ideal for underwater treasure hunting and wreck diving.
The CZ-20 is waterproof to a depth of 250 feet. Remember, always
practice safe diving methods.
When diving with your CZ-20, use the shortest stem length
possible, with the extra cable wrapped tightly around the stem,
as closely as possible to the control housing. Never hipmount
your control housing while diving.

5. Make sure the O-ring and both sealing surfaces are
clear before reinstalling the battery cover. THIS IS
EXTREMELY IMPORTANT!
6. Finger tighten the thumb screws, then carefully
tighten again 1/4 turn with a coin or screwdriver.
