JWFishers PT-1 Pipe Tracker
JW Fishers has added the PT-1 pipe tracker to its extensive line of metal detectors and cable trackers. This device is a sensitive, pinpointing magnetometer. It works equally well on land, and in fresh or salt water. The PT-1 was specifically designed to locate and track iron and steel pipelines and armored cables, but it will also detect all ferrous (iron/steel) targets buried under any kind of material, including concrete, with no loss in detection range.
