Coinmaster GT Owner’s Manual Introduction Disc cursor Low battery indicator Reject icons Backlight indicator Sensitivity strength Depth bar Tone ID mode indicator Numeric VDI and depth The Coinmaster GT (or CoinGT) is an easy-to-use metal detector with features and performance that rival more expensive models. The CoinGT has automatic ground tracking (AutoTrac®) which maximizes performance across many different ground conditions.
Coinmaster GT Owner’s Manual Assembly 1. Remove all parts from the shipping carton and check assembly diagram to ensure all parts are present. 2. Install black rubber washers on fiber clevis/lower rod, insert clevis lower rod onto loop ears. Use only nonmetallic washers, fiber bolt, and fiber thumb nut to secure loop/search coil to clevis/lower fiber rod. 3.
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 camlock so that search coil can be held near the floor without stooping over. 6. Adjust the elbow cup strap so that it is loose enough for you to slide your arm in and out without loosening each time you want to set the detector down.
Coinmaster GT Owner’s Manual shelf life. It is a good idea to carry back up batteries. 7. A rechargeable NiMH battery pack may be purchased separately. Rechargeable batteries typically provide similar or slightly less run time than alkaline batteries. QuickStart 1. Turn on the power. 2. The CoinGT has automatic ground tracking. To speed up the initial tracking process, find a spot free of targets and bob the coil up & down a few times (optional). 3. Sensitivity (SENS) defaults to a reasonable level.
Coinmaster GT Owner’s Manual Controls ON/OFF Besides the obvious, the ON/OFF button also controls the display backlight. Press and hold the button to toggle the backlight. SENS The Sensitivity control increases or decreases the responsiveness of the CoinGT. Normally, this determines how deep the detector will “see” a target. However, increasing the sensitivity not only increases the response to target signals, but also that of ground signals and electromagnetic interference (EMI).
Coinmaster GT Owner’s Manual Use the circular arrow button to cycle the disc cursor through the 9 ranges, and press the disc select button to toggle the selection of a particular range. The range is disabled when the symbol is displayed. TONE ID By default the CoinGT has a single tone audio response regardless of the type of target. Pressing the TONE ID button enables a multi-tone audio response whereby each of the 9 target zones has a different audio tone.
Coinmaster GT Owner’s Manual like Disc mode, the All Metal mode requires that the coil be in motion in order to respond to a target. If the coil is held steady over a target it will get tuned out after a few seconds. When the Pinpoint button is pressed and held it performs the second function of enabling Pinpoint mode, which is typically used to assist in pinpointing a detected target. Pinpoint mode is a true static mode in that audio response is maintained as the coil is held steady over the target.
Coinmaster GT Owner’s Manual zone. Rejecting a zone only affects the audio; the display will still show target information even if you can’t hear an audible response. The CoinGT display includes a backlight for extended hunting. Press and hold the On/Off button to toggle the backlight. In daylight it can be difficult to tell whether the backlight is on or off, so a backlight icon is also displayed. The backlight will reduce battery life by 30% so it’s best to turn it off when not needed.
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 considered only a probability estimate. As we’ll see in the next section, the probability decreases with depth. An excellent approach is to work with test targets (especially planted at different depths) to get familiar with target responses.
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. If it is the latter, the only recourse is to reduce the sensitivity level until the detector can operate smoothly.
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. The bottom line is: swing level, moderate speed, and overlap.
