I have 2 CZ's & will be willing to sell just one.
Older Ser.# 1121- Los Banos made CZ3d , fine tuned by Tom Dankowski . His tests results showed 11.4" in Florida soil. Has excellent 8" & 10 1/2" coils . $575 + shipping.
Older model Los Banos made CZ5 , repaired [ batt. connections ] , serviced, & re-calibrated by factory. Very good condition It's depth is just slightly less than the one above. Comes with 8" coil , but can add the 10 1/2 " coil from above. $ 400 with 8", & $475 with both coils. + shipping.
I think these prices are very fair for such great quality detectors .
PM me if interested.
