    Coinmaster GT Owner’s Manual Assembly 1. Remove all parts from the shipping carton and check assem- bly diagram to ensure all parts are present. 2.

    Coinmaster GT Owner’s Manual 5. Grip the instrument by the handle, with your arm in the elbow cup with strap and sweep the loop/search coil over the floor. If the instrument fit feels uncomfortable, readjust clevis/lower rod length with spring clip button and cam- lock so that search coil can be held near the floor without stooping over.

    Coinmaster GT Owner’s Manual Controls ON/OFF Besides the obvious, the button also controls the ON/OFF display backlight. Press and hold the button to toggle the back- light.

    Coinmaster GT Owner’s Manual same responses as foil, nickels, and pull tabs. Likewise, pull tabs often look like nickels and vice-versa. Target ID is by no means foolproof and should be consid- ered only a probability estimate. As we’ll see in the next sec- tion, the probability decreases with depth.
  • Page 12: Overload

    Coinmaster GT Owner’s Manual Overload If the received signal is too large to process the CoinGT will give an overload response. This is heard as an obnoxious alarm sound, plus the display will read “OL”. An overload can be the result of a large metal target near the surface, or from extreme ground mineralization.

    Coinmaster GT Owner’s Manual Wrong Right Finally, sweep speed affects target response and depth. Some detectors are designed for an exceptionally slow sweep speed, some need a fast sweep. The CoinGT works best at a moderate rate of about 3 feet per second. Somewhat slower or somewhat faster is fine, but whipping the coil at a fast rate is a good way to miss deeper targets.
