I tried my GP Extreme at the beach this weekend. First I was trying the Platypus coil and it would not detect a nickel so I had to switch to a Commander Mono coil. Probably 11".
I'm suspecting the female pins of the coil connection have contacts that are too wide apart for the male pins. Have to check it out.
Anyway, what intrigued me was that the Commander Mono coil ignored foil. Even big foil. It detected targets well, there just were not many of them there. It was fine in the wet sand. It took some getting used to to hear the tone whoop with the coil swing though. I'm guessing that's normal - sure could be nicer if it was just a threshold tone. My Equinox 800 would have been sounding off on all the foil bits, driving me crazy. I switched to my CTX and it was much more pleasant to use - lighter, quieter, and seemed to pick up a bit more targets but that may be because I was working a different part of the beach than earlier.
I guess things were too sanded in for the GP Extreme to make much difference. It did find very small things but the CTX is good at that too - just not the greatest at gold chains perhaps.
Let me know if this all seems about right for the GP Extreme.
