Hold unit firmly and separate handle, being careful not to drop 
the control unit and damage it. Place unit battery side down with 
battery cover on table top, or a flat stable surface and grasp the 
unit firmly in one hand and the handle grip firmly in the other.

“Hipmounting” the CZ-21 in this manner takes about half the weight 
off the handle and allows the land or shallow-water treasure hunter 
to search much longer without arm fatigue. 

1.

  Slide the belt clip into grooves on the bottom of the 

control housing. This is a snug fit, and you’ll have to 
bend the clip slightly. 

2. 

Unwrap just enough of the coil cable to allow for 
searching. 

3.

  Slip the control housing onto your belt, left side for 

right handers, right side for left handers. 

NOTE: 

Because of the extreme sensitivity of the CZ-21 search coil, 

hipmounting the control housing may produce a false signal when 
the search coil reaches the end of its arc (on the side that the 
control box is attached to your belt). Depending on your stem 
length  and  how  high  you  have  the  housing  hipmounted,  the 
search coil may actually detect the housing.

WARRANTY NOTICE:

Damage to coil cable at housing connection is not warrantable if 

damaged by excessive force.

If hipmounting, please leave slack in the cable so as not to yank 

the cable from the housing at the end of your sweep.

SETTING UP

32

to your original direction, you’ll receive a single beep 
directly over the target.  

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 position. 

b)

  A  coin  lying  in  the  ground  at  an  angle  (as 

shown) may give a single target response but 
may pinpoint several inches away from its true 
location. Check around the inside edges of the 
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 2 feet, will often give a good, 
strong coin signal. If you’ve dug down a foot 
and widened your hole several times, give up.

FALSE SIGNALS

  Practice!  Practice  over  known  targets.  Practice 

ground  balancing.  Practice  pinpointing.  Reread 
the appropriate part of this manual if you’re having 
problems.
