I bought a used CZ-21 from Grant Hansen this week and Grant was an excellent seller and member of this board. I also was impressed with the detector. It has a 10.5 inch coil and I was concerned that with the larger coil, I would lose sensitivity. That is not the case. Ground balancing was no different than ground balancing a gold detector by pumping and I was amazed at the similarity to a Whites TDI even though the CZ-21 is a VLF machine and the TDI is a PI machine. Discrimination is as good as the TDI was in being able to work a very dirty beach area with lots of nails, pulltabs, bottle caps and assorted metal junk in pieces. Like the TDI, I was able to dial out that junk. I was able to set the disc at 4 and just find coins. Pinpointing was better than excellent. It pinpoints every bit as good as the MXT with the round mono coil. I have not tested the depth as yet and will probably do that today at some time. I will say that the air test was on a par with the TDI and MXT but I think all air tests for all detectors will be similar due to the insulation of air. The build quality compared to the Whites is excellent and, again, I am impressed with the quality of the detector.....jim
BTW I was able to chest mount it like the TDI.
