The 512-hertz FB-R2012 wireless digital locator from Forbest Products can detect buried water pipes, sewer lines and other pipeline. It can be used in normal or noise-control modes for different application environments. Noise control is chosen when 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 lightweight hand-held locator is powered with 6 AA batteries and comes with retractable poles that make it easy to carry. 650/757-4786; www.forbestusa.net
