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.
Sizing, Pinpointing, and Digging
When a target is detected move the coil well away from the
target area and press/hold the Pinpoint button to switch to the
Pinpoint mode. A normal sweep over the target in Pinpoint
mode will give an idea of target size. If the response is narrow
then it is likely a small coin-sized target. If the response is broad
then it could be e.g. a beer can. Small shallow targets can give a
broad response, and large deep targets can give a narrow
response, so use judgement with this.
Once you determine you want to dig a target, use the Pin-
point mode to zero in on the location. A criss-cross pattern
works best, especially using VCO audio to listen for the peak
tone. Watch the ground through the open coil to better deter-
mine the exact spot.
Be mindful of proper digging techniques when extracting
the target. Use the smallest appropriate digging tool, especially
in public areas. Learn how to cut plugs that avoid turf damage
or, better yet, how to “pop” coins. There are lots of videos on
YouTube that demonstrate good extraction protocol.
