Yesterday while using a new 6" DD HF coil with the sensitivity maxed out, I got an overload signal in the quarter range. In the past using the stock coil I would have almost always moved on when receiving an overload signal in that range because of assuming it was either can slaw, an aluminum can or something similar. This time because of the new coil I decided to check it out and after parting the thick grass and clover, there lay a quarter flat on the surface of the ground. Have I been missing out on some good targets by not checking out my coin range "overload signals" using the stock coil? What about Minelab's other X-T coils?
