Out doing some more coin shooting. Again.....I used my favorite coil, the 9" x 12" concentric coil.The different frequency of the MAX compared to the AT Pro (MAX 13.6 kHz / 15 kHz PRO) affects ever so slightly how it reacts to Canadian clad. It doesn't bang quite as hard, but the typical VDI numbers are basically the same, depending in how long the coin has been in the ground and the extent of the oxidization. However, the high signals come in loud and clear for copper and silver. I just use a little iron audio to determine whether I want to dig the target or not. Below are the finds from today!
