The Pro700 Underground Sprinkler Wire and Valve Locator is a tried and true solution for irrigation contractors and maintenance personnel. The Pro700 has been in production since 2008 and was the first wire and valve locator to use external speakers, D batteries, and a longer wand than the old tiny PVC pipe and tackle box. Incorporating a powerful transmitter and sensitive receiver, the Pro700 tracks irrigation wires, finds missing valves and detects damage or cuts to vulnerable underground cabling. The Pro700 has a proven track record of 10 years of finding these problems.
