Re: Re: what to do, what to do?

Those CZ's are amazing.  Even with all the modern advancements, they are just about as deep (or deeper) than anything in an open field on coins.  They can be a little tougher (for me) on colocated foil mixed with a coin.  I also tend to dig my share of old nails with 'em (although the pinpoint sizing tech can usually tell you it's too big for a coin). I currently have a CZ3D and use it mainly for testing against other detectors for comparison purposed.  Brick on a stick sums it up pretty well!  However, it will find a TON of old coins...and deep too.  Does NASA Tom fix CZ stuff other than 3D's?  I don't have a clue what his charge would be though, if he does.
