JW Fishers are finding customers all over the world for their pinpointing magnetometer & cable tracker equipment.

The pinpointing magnetometer is a very sensitive instrument that locates iron and steel pipes buried up to 16 feet in the bottom, and the cable tracker is powerful enough to detect a power or communications cable at more than 30 feet away.

Amongst an extensive list of users all around the world, one company using both of these devices is Gray Diving Services in Australia. Founded in 1945 by William Gray, the enterprise has evolved into one of the largest onshore civil diving contractors in the country. They have the expertise and resources needed to design, construct, and manage almost any subsea engineering job. Gray Diving Services has successfully completed projects across Australia, in Southeast Asia and around the Pacific Rim.

To aid in their pipeline and cable installation and repair work, Gray acquired JW Fishers PT-1 pinpointing magnetometer and CT-1 cable tracking system. Project manager Adam Gunn reports that the PT-1’'s ability to pinpoint targets, even in areas surrounded by steel structures is extremely helpful, as many pipes and cables are near bridges, seawalls, or other  structures made of steel or steel-reinforced concrete.
