Thanks for your efforts on this..it will give me a starting point for when I finally have the detector in my hands, and start hearing the tones for myself.
Just ordered a NOX 900. Been detecting since high school (I'm 63 now). Upgrading from an XLT. Prior to that I had a Garrett and in high school I swung a Coin Hunter?
Using the forum to learn as much as I can while I wait for the 900. Oh, I live on Whidbey Island, so if your in that neck of the woods....LETS HUNT!
