I'm sure this topic has been beaten to death but i just recently purchased a new MXT about 2 week's ago.This past Sunday the mxt went on it's 1st maiden voyage cw relic hunting which is my passion.It came with the 'super 12 'coil on it and while i was detecting bullet's/button's at appox 7-9 inches in this Virginia 'hot soil',i'm pretty sure i missed a few relics also.My question to the mxt expert's are if you were going to relic hunt in hot soil what would be your coil of choice?I'm thinking about buying a 10x12sef coil, whites 10'dd, or the 6x9 dd,...keep in mind i'm 90% of the time in the wood's an kinda thick.Thxs in advance for any/all replies.
