GENERAL DESCRIPTION
Both the 7200 & 9200 Digital Metal and Valve Locators use
computer-driven circuitry to assure easy and accurate
locations of buried metallic objects. Although each has
different features they share the same ergonomic, collapsible
design along with fully automatic operation all from a single
trigger. Both are used extensively by municipalities, water
and gas utilities, contractors, maintenance people and others
to locate valve caps, boxes, valve risers, manhole covers, etc.
