or maybe a less biased responce, your post probably would have been better in a general metal detecting forum. I'm certain if you asked the same question in the DFX forum they would all say their's is the best (even though all I hear about it is that it's very hard to program & not that deep).
No hard feelings though....I edited my post below & do understand how hard it can be sometimes to be sure you get a detector that fits your needs. For some further Coinstrike info., do a search for the "Coinstrike Homepage". Lots of good info there to help you make a good decision.
good luck,
