Anyone good with a Whites MXT All Pro? in COINS, TREASURE, and RELICS Posted February 10, 2015 Do you X over the target. Remember it is not a cone under a DD coil it is more a plane coming down along the axis of the coil and the object could be anywhere along the edge. You have to start by moving your coil in a straight line (while swinging it back and forth) until you lose the signal and then run the coil at 90 degrees to your previous straight line you were moving on. The item should be under the front edge of the coil where the two lines had the last signal.
