Monte was right on about this machine! And thanks for the pm, Monte. After only 30 minutes I loved this machine! Of course, I've been doing this for over 40 years, but still-I knew this was different than what I've been using. True-most finds are within the 3-4" range and ID is a crutch at times-but the FUN factor FAR outweighs being a die-hard beep-dig enthusiast. One target about sums it up. I got a tab/zinc varying tone/ID signal. It was a trigger off a toy gun. You could see where the tones/ID were actually FOLLOWING the outline of the trigger! I LOVE this machine! Just too much to post about at one time-and only after 30 minutes.
