?? on CZ20 in autotune mode

[therover]

Hello all,

I have a question about the CZ20 in autotune. In that mode, is it more or less stable in the wet salt sand than in discriminate mode ? The reason I am asking is I am thinking of purchasing one, as opposed to a PI unit and I am curious as to how much depth and sensitivity I would be giving up vs a PI unit in autotune.

Some of the salt beaches I hunt are really littered with nails/bits of iron and sometimes there are very few targets. In the event I run into tons of nails/bits of iron, I would run in discrim mode, but when it's pretty qutie, I would run in autotune. I also like the idea of being able to run in autotune and then switch to discrim.

I am a Fisher guy from way back and I like the warranty, sturdiness of their units, the ability to hip mount it and I want a multi freq detector for the beach, hence the CZ20.

Any help would be appreciated since I am ready to pull the trigger on a water unit.

Thanks,

JC

between the two modes. But then, I've never had the opportunity to take my 20 or my 5 to saltwater. From what I've read, you can expect better depth in wet salt sand than you can on dry land, due to the conductive nature of the wet salt conducting the signal further down.

Auto-Tune, from what I've been told, produces a wider field, especially at depth, than Discriminate does. Once you get a target, just flip down to 0 Disc. and ID it. I've been doing this for years.

With experience, I've learned to tell, by ear, small iron/rust targets in the ground in Auto-tune. Coins and rings usually hit a little harder, even when they're deep. But, you're right, if you're on a bed a nails, run in 0 Disc. so you can hear what kind of targets they are.

You will get more depth in auto.Sometimes you can switch to discrim or pin point and not hear anything.The target is to deep!If I'm not finding much or there is little to no trash I'll run auto for the extra depth and listen for slight drop outs of the threshold hum.Most of the time I'll run in discrim mode 0.Hear all 3 tones and dig the medium and high tones.The CZ20 works well in salt water in either mode you choose.Get a Very Heavy Duty Scoop or backhoe.You're gonna need it.

PI units will pick up a Bobbi pin at a foot but will break your back. My choice would be the CZ as you have a choice of what mode to use and of course can always double check in Disc..My take on a CZ in autotune its a bit deeper than Disc. mode but just covers a wider area for more coverage per sweep....
For those that use PI units and do well go for it but my choice would be the CZ because of the above info....
