  • Specifically designed for anomaly detection, the SDM-4000 is the perfect economical tool for locating ferrous metal objects, on bottom, or buried. This magnetometer is depth rated to 4000 ft. and will operate with cable lengths up to 4000 ft. The depressor wing design uses the forward motion of the boat to keep the tow fish down. This saves on the amount of cable required to reach a certain depth.
