CZ70 PRO , in trash

[Flintstone]

Can anyone tell me how good the CZ70 Pro dose in trashier parks? I have the 5" coil, and was thinking that if set the disc. up to knot out tabs and bottle caps that it will still go deep. I have been told that it still goes deep with disc. up high anyway. Thanks For any help. Flintstone

I think the digital CZ's are a little better in trash like the CZ-70 You have. I would just leave my disc. at 0 and listen to the tones. And set the sens. to 4 and volume at 4 and just dig the sweet soft tones. That is the way I hunt in trash with all my CZ's.

Thanks Harold, This place was a old drive-in, and so many pull tabs that you can rake them up with your foot. I am 62 years old and my family went there before i was born. I don,t think i could hunt in o disc. there is just so much trash. Thanks Flintstone

I've hunted an old drive-in for several years but I have used digital and analog Fisher CZ's and in this type site they have trouble. If you have a WhitesXlt or Minelab Explorer or Etrac you'll find more silver and you'd be better off running a very high disc pattern. The CZ's false high tone too much in all the trash when running a very high amount of disc and you dig too many tabs when running low disc because they will read higher up the scale at these old drive-ins due to all the copper wire, and speaker parts under the ground. Yours may be different but I've hunted a couple of these drive-ins and got the same results. I never used the small coil due to the large area to cover but heck that may be exactly the right combo to pull all that silver. I always liked the CZ's at older home sites.

That's what is used here, too. Works like a charm.

My thoughts on hunting trashy locations with a CZ is that the 5 inch coil is necessary; until you have removed all the trash!

Two or more targets at once under the coil make it near impossible to get a good ID or a good target location. A tab and a piece of copper under the coil at the same time will average up above tab in ID. If you go to pinpoint, raise the coil and are able to isolate a target you may get a reasonable ID going back to discriminate mode with a slow, narrow coil movement just over the target with the raised coil. It is better if the coil is small enough to not get multiple targets directly under it at the same time.

The 5 inch coil gets many more targets isolated and ID'd. Work slowly and methodically and good targets can be pulled from trash.

If you run high discrimination and have two targets under the coil, if one of them is discriminated out and nearer the surface than the good target, you most likely won't detect either target (masking). Masking is part of the reason I run the CZ with the discriminator set at 0 and listening to all tones. If I don't want to dig low and mid tones, I won't dig them, but I listen to them. I will also hear a low to high tone bounce and take a little more time to figure out if it is likely iron or likely deep non-ferrous. Sometimes I only dig mid-tone and nickle ID's. Depends on the day.
