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.

Can't beat the Excalibur II for beach hunting
I have owned the Excalibur 800 blue version just prior to the newest Excalibur II and now own the Excalibur II 1000.

The Excalibur II 1000 is one awesome beach machine.

I really like the coverage of the 10 inch coil and the new electronics in the II's. The newest version seems to be more stable than the older versions. I also like the design of the new coil as the new 10 inch coil is as easy or easier to pull through the water as the old 8 inch. It is lighter for sure and also is slimmer which aids in the movement through the water.

Pin pointing is a snap with the Excalibur II. It does take practice but the pin pointing will come to be natural after a very short while.

I like to run in all metal all the time and use the discrimination mode to check to see if the target is iron or something of value.
All metal mode does seem to be deeper in most instances.


I would highly recommend getting a straight shaft for the Excalibur as the ergonomics of the Excalibur's factory shaft is really uncomfortable.
The older versions of the Excalibur had the older headphones which were uncomfortable and not really all that good. The new Koss yellow headphones are a marked improvement over the older blue headphones. Not having to change the headphones to after market headphones will save you around $175.

I would also recommend getting an extra battery pod for the Excalibur as you will be spending lots of time on the beach with this machine.

Don't sell the Excalibur II 1000 short for land detecting. I use mine for land detecting and it is as deep as the Sovereign which is the land only version of the Excalibur which is to say that it is very very deep. 17 frequencies running all at the same time allows for most targets to be detected even in some pretty bad conditions like black sand.

Don't forget that you will need a good sturdy sand scoop if you are using the Excalibur on the beaches. Hit those beaches at low tide and watch what you will find. Amazing!

If you are looking for a great amphibious detector then the Excalibur II 1000 is a very good choice.
