Fisher CZ21-8 Underwater Metal Detector Review
The Fisher CZ21-8 underwater metal detector is a high end underwater metal detector that you can use in both fresh and saltwater up to 250 feet depth. The control housing can be easily removed for hipmounting or it can be chest-mounted with an optional chest harness. It is one of the best saltwater metal detectors that has ever been built.
One of the key features of this Fisher metal detector is the audio tone target id. This allows you to distinguish iron from gold on your treasure hunting adventures. It weighs 5.3 pounds and uses 4 9v batteries.

Pros and cons of the Fisher CZ21-8 metal detector
What We Liked
What We Didn't Like
We could not find many customer reviews for the Fisher CZ21-8 , the couple we could find had all a 5 out of 5 rating.
We found one really great review we wanted to share here:
Simple no frills metal detector that is tuned for saltwater. I currently have two detectors I use, a third one(ACE 350) I gave to my son to use. Since I bought this CZ-21, I have really enjoyed beach hunting!! My other machine is a Garrett AT Pro that I bought with gift cards from my sister for my birthday. The AT Pro is decent for the beach and I can't knock it too much. After all, I found my first gold ring with it. But, the CZ 21 outshines it at every aspect. This detector is a Dual frequency VLF machine, thus it runs really stable in saltwater. My AT Pro is a chatty thing in the water. Yes, those who are obsessed with the AT Pro tweak it to quiet it down, but that reduces the depth as the AT Pro is a single frequency VLF machine. I have found a gold, silver and tungsten ring with my Fisher CZ 21. I have also recovered over 20 fishing sinkers as well. For those who hunt the surf seriously, you know you have to hit sinkers to find the gold. The CZ 21 is waterproof to 250 feet and is used by divers. The only downside to the Fisher is that the coil is hard wired, along with the headphones. There is no swapping out coils without sending the unit back to Fisher. For me, it is not a big deal at all. I like my 8 inch coil as is. The unit itself is pretty hefty, but I chest mount mine. That way, I am swinging the coil only!! It is light weight and I can swing it for hours without feeling tired.
The detector has three tones, low, medium and high. No fancy LED readout or numbers to worry about. Just turn the knobs and go. I love listening for the tones as it lets me know what is underneath the coil. With this unit, you can also run auto tone that picks up everything. To ground balance, you turn the knob and do it the old fashioned way, by hand. There is no auto ground balance feature, you, the user are in control. IF you want a well built machine with no frills, and want to find gold or silver jewelry, along with coins, get this machine.
