Transponders

 

Autonomous  Hydroacoustic Transponder Release: "AHAR-MP", "AHAR-EC"

Hydroacoustic transponder releases of AHAR-series are very reliable devices, they are in use for uncoupling different underwater equipment from anchor. Releases are necessary components for mooring buoy stations and any other pop up equipment. Compact, portable device is easy -to-use and is ready for many applications.
