The FB-R2012 512 Hz wireless digital locator from Forbest Products detects buried water pipe, sewer lines and other pipeline. It comes with the FB-T2011 512 Hz sonde transmitter and can be used with a camera head with a built-in 512 Hz sonde transmitter. It comes with two operation modes – NORM and NOISE CONTROL – for different application environments. NOISE CONTROL is chosen where there is interference. A shift button enables sensitivity grade conversion between near and far for locating and pinpointing the location and depth of the transmitter. On-screen status indicates the signal strength of 15 levels and battery volume. The hand-held locator powered with six AA batteries is lightweight with retractable poles and easy to carry. 650/757-4786; www.forbestusa.net.
