Coin-sized objects will be detected up to 9" deep. The 3-segment graphic
DEPTH INDIC TOR
indicator is calibrated to coin-sized objects.
Objects other than coins will still register on the 3-segment depth scale, but the
depth indication will be relative. For example, all 3 segments illuminated could
indicate a coin buried 9" deep, but could also be a very large object several feet
deep. Use the Depth Indicator in conjunction with the Target Category Icons to
gain more information.
If a metal object or highly magnetic soil is too close to the searchcoil, the
OVERLO D W RNING
detector will overload and a "
make a rapid, repeating mid-tone warning sound. Overload will not harm the
detector, but the detector will not function under these conditions. If overload
occurs, raise the searchcoil to detect the target from a greater distance, or
move to a different location.
