Acoustic Release

R12K Acoustic Transponding Release

The model R12K Deep Sea Acoustic Transponding Release is the first product in Teledyne Benthos's release line to benefit from a new electronics architecture. This new architecture provides new features and establishes the R12K as the most technologically sophisticated release in its class. Battery voltage and percent remaining indicators are complemented by a tilt accuracy indicated in one degree increments. With a positive indication of release status, operators have complete awareness of the condition of their releases. To view more info click here.

Bottom Finding Pinger

The bottom finding pinger, used in conjunction with a standard 12 kHz shipboard bathymetric recorder, can be used to monitor the height off bottom of instruments, or sampling equipment being lowered through the water column. The BFP-312 can be used for precise positioning of CTD instrumentation, fishing nets, coring tools, water bottles or other items, where accurate vertical positioning relative to the bottom is required.

Precision pingers and positioning beacons require high power, long life and a high level of frequency and repetition rate stability to allow asynchronous operation with shipboard recording and processing instrumentation. To view more information click here.
