The Depth Multiplier is simple to use as all that's required on the ADS 7 is to hook it up, put it in all metal mode, set the threshold level and retune it using the retune switch when the threshold drifts.
Instructions:
When you've attached the Depth Multiplier, turn the detector on, select all metal mode and set the threshold level to a barely audible level. The threshold sound may fluctuate due to several reasons including temperature or ground conditions. If this should occur, retune the detector using the retune switch.
Search Procedure:
Walk forward with the Treasure Hound Depth Multiplier pointing straight ahead and level or parallel to the ground. Do not scan the Treasure Hound as when using a standard searchcoil. When searching for buried objects, walk back and forth following parallel lines. Spacing between the scan paths may range from one foot to several feet depending upon the size of the targeted object. All types of metal will be detected, including iron, however most surface trash and small pieces of junk metal will not be detected. When you get a signal, stop, back off until the signal is gone and then approach the target from four directions in 90 degree increments. Mark the position as soon as you get a signal and the target will be in the center, between the four marks.
Also, when searching with the Treasure Hound Depth Multiplier, the Ground Balance and Discrimination control functions are inoperative. This means that when searching over highly mineralized soil, detection of ground disturbances may occur as the detector is raised or lowered. In most instances these disturbances are minor and almost non-existent, when the Treasure Hound is kept level to the surface while searching.
