The 725K underwater metal detector is an ideal product for underwater security checks, explosive ordnance disposal, salvage opera-tions, and forensic investigations. It uses a dynamic pulse inductionmode, which can avoid interference from underwater metal instru-ments and can detect underwater substances that contain iron, donot contain iron, and are made of alloys. The target object can bealerted through an audio signal. It has strong detection capabilitiesand is suitable for detecting large unexploded explosive devices,such as 105mm shells, bombs, or torpedoes. The detection depth isabout 2 meters, and it can also detect the smallest buried metalmines. When using a large UXO detection coil, it can detect smallmetal objects up to 1.5 meters deep.
