FISHER CZ 21-TESTS

Comments

Well made waterproof Beach detector, a very easy detector to test because it only only found a few items on my test bed!
I think this is designed to find coins and the odd ring on the beach cant see any other use for it , would be fairly useless on land although some people do tend to use it for general detecting

DEPTH TESTS

The depth tests are set up to gauge the power of the detector, all iron is removed from the hole.

Various size items are buried at good depths

COIL SIZE

Standard 8’’ coil

CAN A CARTWHEEL PENNY BURIED AT 16’’ GIVE A SIGNAL

NO

GEORGE 111 HALFPENNY

MAXIMUM DEPTH

10’’

5 PENCE MAXIMUM DEPTH

8’’

CUT ¼ OF HAMMERED PENNY MAXIMUM DEPTH

NO

CAN A HOARD OF 100 MIXED COINS BURIED AT 18’’ GIVE A SIGNAL

NO

DISCRIM TESTS

The tests below are to see if the detector is capable of giving a signal on a non ferrous target while iron is placed on top of it and around it at different depths

CAN I GET A SIGNAL FROM A 20 PENCE BURIED AT 8’’

2 NAILS BURIED AT 2’’ DIRECTLY ABOVE IT

NO

CAN I GET A SIGNAL FROM A 20 PENCE BURIED AT 8’’

2 NAILS BURIED AT 5’’ DIRECTLY ABOVE IT

YES

CAN A GET A SIGNAL FROM A 20 PENCE BURIED AT 8’’

2 NAILS SITTING ON TOP OF COIN

YES

CAN I GET A SIGNAL FROM A HAMMERED PENNY 20 NAILS ALL AROUND IT BURIED AT 2’’

NO

CAN I GET A SIGNAL FROM A HAMMERED COIN BURIED AT 2’’

A LARGE/RUSTY IRON HOOK IS BURIED 3’’ BELOW IT

NO

CAN I GET A SIGNAL FROM A HAMMERED PENNY NEXT TO 4’’ BOLT

BURIED AT 2’’

NO

CAN I GET A SIGNAL FROM A 20 PENCE BURIED AT 2’’

2 NAILS ALSO BURIED AT 2’’-NAILS 4’’ APART COIN BETWEEN THEM

YES

CAN I GET A SIGNAL FROM A 20 PENCE BURIED AT 5’’

2 NAILS BURIED AT 2’’ DIRECTLY ABOVE IT-4’’ APART

NO

CAN I GET A SIGNAL FROM A 20 PENCE BURIED AT 8’’

WITH 2 NAILS BURIED AT 2’’ DIRECTLY ABOVE IT 4’’ APART

NO

CAN I GET A SIGNAL FROM A 20 PENCE BURIED AT 6’’

WITH 4 NAILS BURIED AT 5’’ DIRECTLY ABOVE IT

4 NAILS AT 7’’ DIRECTLY BELOW IT AND 4 NAILS ON THE SAME LEVEL

NO

COKE/SENSITIVITY

A few low conductive targets will give the same signal as Coke , so if you are rejecting Coke you may miss them

CAN IT FIND A GOLD CHAIN WHEN COKE IS REJECTED

NO

CAN IT FIND A LOW CONDUCTIVE CUT ¼ WHEN COKE IS REJECTED

NO

CAN A GOLD CHAIN BE FOUND WHEN COKE IS NOT REJECTED

NO

CAN A LOW COND CUT ¼ BE FOUND WHEN COKE IS

NOT REJECTED

NO

CAN IT FIND A LOW CONDUCTIVE VERY THIN SILVER EARRING BURIED AT 2’’

NO
