CZ70 finds silver in its first hour long yard hunt

[cometguy]

I bought my CZ70 to take to the beach. It did a decent job there but things I have read lately told me I needed to try it as a regular hunting detector too. I got out tonight to a farm house yard that I have hit with both my CZ3d and my F75. I have found things there before, but this was just a quick hunt to see if the CZ 70 would produce. I am not sure if they are meant to run silent, but this one did until it hit a target. My first signal was 8 inches deep and turned out to be a 1917 Wheat. I got the little friendship ring next. The Shell presidential token almost gave me a heart attack. Then right before I quit I got the 1927 Mercury out of some gravel. I had to quit quicker than I would have liked. I think I will play with the CZ70 again and may hip mount it for a long weekend hunt.

Yep properly ground balanced and sens. around 4 will knock the socks off most of the new units depthwise and yep runs quiet....little or no EMI with this baby under most conditions...

I thought they were older than they are. I saw a field test for 2003. It showed a price of $999 for the CZ70 pro. I feel like I got a bargain on mine. I did have the issue of not enough tone generated to ground balance but the suggestion to move the sensitivity up to 10 and then reduce after balancing got me the tone to get it done. It ran with no tone until it hit a target. I was running sensitivity up at about 6 and saw no problems. Do you lose depth when you push up the sensitivity? I dug less junk with it and found quite a few keepers in a very brief hunt. I think I will use it more now that I have played with it.

All CZ's ground balance in autotune with the sensitivity at max and volume pretty much maxed out as well ( per the manual). These settings then make an audible 'threshold' type sound where you can then distinguish when bobbing the coil, the changes to the sound and whether to turn the GB knob clockwise or counter clock wise until the sound stays constant and does not change when bobbing.

Once done, and you switch to discriminate mode, you turn down the sensitivity to the 4-6 range and volume to where you want it.

A CZ will start to tell you when you need to ground balance again, or if the sensitivity is too high, by higher amounts of falsing when sweeping the coil. If the unit starts to false a lot, the first thing you should do is re-ground balance, especially if the unit was not falsing much as whatever sensitivity level you were using. If after you re-ground balance, the unit still falses more than usual, then you should turn down the sensitivity a bit.

Seems like in my neck of the woods be it either the mineralization or different sens. parameters in older or newer CZ70's 4 is tops in N.E. Pa. but some can get up to 6 and still keep the unit stable..In any case having used earlier CZ's both analog or digital I ran them 6 to 8 but never found a place where I could go higher..In any case using a CZ5 or CZ7A pro or any of the older models a CZ70 will go as deep as previous mentioned ones with higher sens. so has to be internal changes in the CZ70 and CZ3D where a 4.5 or so is tops at least in my area.
As far as your ground balance you have it balanced correctly so you should get super depth along with stability...and some nice silver in the pouch...

PS: honestly first time I used a CZ70 locally I set the sens. at 6 and thought something was wrong with my unit as it was noisy until I turned down to 4..as far as the depth issue I tested in my 20 yr. old planted test garden to get the above results..and indeed my CZ70 was working properly..live and learn...

i always hip mounted mine!..makes a big difference,as the pole weight is reduced to
approximately 2.5 lbs....

very true ..dan!
at "4" gain is just as deep,or deeper than modern digital equipment!
i know,i owned one!.."crackerjack" coin sniffer!..just sayin!

Nice finds Don.

The CZ's don't only "hang" with todays machines...they run right along side of 'em

I love my CZ70Pro.
