The new CZ-21 arrived last night. I put it together and went out into the shop to do some air testing. I had a bunch of gold rings I have found in the past, some new and some old coinage, a 25" gold chain, and a pull-tab.
I like the different tones the CZ gives to give you a hint what's under the coil. I noticed the pulltab near the center of the coil sounds like gold, but when it gets to the edge of the coil it goes to a high tone like a coin. The shaft that comes on the CZ reveals some thoughtful engineering design. It works perfectly as a long straight shaft or it can be collapsed to work in a diving mode. I don't have to go purchaset a straight shaft like on some of the other TOL units. The hand grip seems to be at a good angle. I'd never use it wading with the control box mounted on top of the handle. Top heavy as heck. It was easy to get a spare diving weight belt and hooked it up as a hip mount. One pull, as on my weight belt, and I am unattached from the control unit.
When I swung the gold chain in front of the CZ...NOTHING. I even bunched it up in my hand and waved it in front of the coil...Nothing. I then pulled the TS off the wall. Repeated the same tests with the same objects. The TS has one tone. However, when I swung the gold chain in front of the coil the TS gave as loud as beep as the heavy gold band is also used. I balled the chain up and it was even more solid. Now I did not measure anything with a ruler. But I can say with confidence that the TS air tested better with the target farther from the coil than did the CZ. I would guess the TS got at least 2" better on the air test. That's disappointing as heck.
I did get the CZ with the 8" coil. I was advised to get the 10" but that sometimes is unweildly when in a dive mode. I haven't tried the CZ in the water yet. I feel it'll be fine. But unless you need the saltwater operation, which the CZ will do and the TS won't, my preference in the FW is still the TS. If you can get one, they are a lot less expensive and look at the lifetime warranty. The TS is the sleeper of the freshwater detectors. jim
