CZ-70

Hello! I am from Russia. I am F-70 and Cz-70pro detector user. Cz-70 I purchased recently, S/n 11292335. I did the test of air tests of Dime 1993 =9" and 25 cent 1965=10,5" Disk. = 0 (Not Auto-tune), Sens. = 6, Gnd Bal = 10, Volume = 10. Searching ring 8". Is it normal or I must point Cz-70 at the repeated calibration? Thank you.

I have tested numerous CZ-70's(and 3D's) of all different serial #'s over the years. Your detector performs OK from what I have seen. Many CZ-70's, either 10292... or 11292... perform to this level but some are much hotter. I still don't understand how there can be so much variability in machine performance but it's true, especially with CZ's I guess due to all the tuning adjustments required and the individual electronic components within each machine. Because of this, it seems each CZ is somewhat unique in how it performs overall-ID ability and depth-air/in-the field. I doubt it can be tuned much better to make it "hotter" but Tom surely can tell you more about that. This same variability holds true with CZ-3D's and even E-tracs too. I hope that helps...HH

Sounds a bit weak....and wondering if you have the coins flat/parallel to the coil.

Thanks Tom! Coins in parallel the coil. The coil on 8 has sold, I wait the coil on 10, I will try. At me was CZ-70 earlier, it seems to me, it was hot. I doubt that at us in Russia can adjust it, there is no data how to adjust

Just curious.......... try a sensitivity setting of '8'....and also '10'.....and see if there are any improvements.

At installation on 8 or 10 there are no improvements. Appreciable growth is between 4 and 6.

Okay......it just sounds like your unit is slightly weak.

Thanks.

Has received the coil 10 ", has made tests all well.


Probably, whether technically to make for CZ coil DD? Whether me probably it interests purely theoretically?

There are no DD coils for the CZ. The attempt has been made......with prototypes; however, the CZ's ID circuitry fails with a DD coil.
