Most helpful review for Fisher CZ 21

CZ-21, an excellent land and water machine
The CZ-21 is an excellent and easy to use metal detector. Once you learn to use it, you will do very well. It is easy to ground balance and it can be rod, chest, or hip mounted with no problems. It is waterproof down to 250 feet and comes with a straight rod mount that can also be used for diving. The detector, when used in the AutoTune (a wide scan all metal mode) setting is very sensitive, and its 3 tone ID makes detecting a pleasure.
If you want gold, dig the mid tones.
If you are hunting for coins, dig the high tones. If you hear a low tone - it is probably iron.

A low/medium means a possible gold target next to iron. The detector will have trouble finding tiny gold necklaces or tiny chain link bracelets unless they have a clasp, but then the other brands of water detectors also have difficulty in finding such targets.

Be sure to swing the detector coil slow in the water and you will have great success. The pinpoint button takes some getting used to, but after a while in the water you will not even bother using it. Overall, the CZ-21 is an excellent and well built detector that can be used on land or in the water. And, it is proficient in both ocean and fresh water as well as on dry or wet sand.

Excalibur 800 dream machine.
Just so easy to use. I don't mind the weight that seems to bother others. Great depth, perfect pinpoint. The one and only problem I have had (and I assume everyone does), is pull tabs and other aluminum gives such a nice tone. I have been using this machine for about 3 years and am amazed by the sensitivity. Also with practice the tone variation lets me guess the target 80% of the time. So far it is maintenance free and I use it in fresh and salt and on the beach. A Classic!
