I remember when that first came out. Sheesk has it already been 21 yrs? The only things I didn't like about that machine, was:
a) the ID accuracy wained after the first 6 or 7" Beyond that, everything sounded the same.
b) it had a fondness for nails, which would frequently bang up in the coin range. So the advocates would tell you that the way around this problem, was to only dig the targets which repeated consistently. And to skip any one-way signals, or ones that waffled between IDs, etc.... But the problem was, that those same advocates would admit that the deeper coins could waffle between ID's, and/or give one-way signals!! So which is it ? They also had ingenious methods of comparing the all-metal mode pinpoint, with the ID and such, to tell them nail-falses. But pretty much even the CZ experts, when you pressed them, would admit that the ID wained at depths.
c) I never cared for the silent search.
Nonetheless, they did great on the beach, and furroughed fields with that. There was a guy here with a 10" coil on his CZ, that would frequently go up to a foot deep on the beach! And they were very easy to use.
