Sizing, Pinpointing, and Digging
When a target is detected move the coil well away from the
target area and quick-press 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 have determined that you want to dig a target, use
the Pinpoint mode to zero in on the location. A criss-cross pat-
tern works best, especially using VCO audio to listen for the
peak tone. Watch the ground through the open coil to better
determine 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.
