FALSE SIGNALS
problem, try one or more of the following:
a) Keep your sweep smooth, slow and low to the
ground
b) Check your ground balance
c) Lower your sensitivity
d) Make sure your search coil is properly secured
and the cable connector is firmly tightened.
9. DIGGING TOOL: If you’re carrying a metal sand
scoop, digging knife, or screwdriver, hold it behind
your back or keep it above your waist. Your CZ-5 is
sensitive enough to sound off each time you sweep
the coil beneath it.
10. ELONGATED FERROUS OBJECTS: If you get two
beeps close together and can’t find either target,
you may be near a nail or some other long, ferrous
object.
Fortunately, in most cases your CZ-5 will identify
these objects correctly. In all cases, the target will
be between the beeps, or if you sweep at right
angles to your original direction, you’ll receive a
single beep directly over the target.
11. OTHER TARGETS THAT AREN’T THERE: Good lock-on,
repeatable signals but nothing there.
a) Shallow coins (at or near the surface) or coins
on edge will give a double beep, one on either
side of the coin, just like a nail. Like the nail, the
coin on edge will give a single beep directly
over the target if you sweep at right angles to
your original direction.
b) A coin lying in the ground at an angle may give
a single target response but may pinpoint several
inches away from its true location. Check around
the inside edges of your hole. If you still don’t
find it, enlarge the hole by a couple of inches.
c) A large deep target, like a buried pipe or a
manhole cover at two feet, will often give a good
strong coin signal. If you get a depth reading of
four inches and you’ve dug down a foot and
widened your hole several times, give up.
