The perfect instrument for finding
valve boxes, curb boxes, and manhole covers beneath soil, snow, or
blacktop. Easy-to-use, sensitive and configurable, the GA-72CD will
locate items as small as 1/4" nails (at depths of 1 foot) to well
casings buried to eighteen feet.
Magnetic Locator detects the magnetic field of both ferrous objects and
energized power lines. An audible detection signal peaks when the
locator's tip is held directly over the target. The unit has an
easy-to-read digital bar graph that displays both the signal strength,
polarity of the object and battery status.
