I detect in some pretty highly mineralized soil(it contains a lot of magnetic black sand from Basalt rock.) I think I need more depth to reach the older targets at a 104 year old home site that I've been working. I am mostly after silver coins. The place has a lot of iron trash -of course! I am not sure which coil I should buy. Any suggestions as to what is the BEST choice.
Thanks, Bill
