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.

Specifications:

Acoustic Deck Set

The DS-8750 Acoustic Deck Set is a low-cost companion to the Benthos Acoustic Release Model 875-A and 875-PUB. It is ideally suited for basic release operations requiring only command capability.

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.

High Power 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-312HP can precisely position 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.

Hand Held Acoustic Tester 

The Hand Held Acoustic Tester TU-1000 is a full function “in air” predeployment acoustic tester for Benthos’ full line of acoustic transponders and releases. This battery operated, lightweight unit is capable of generating all Benthos FSK commands and interrogation frequencies. Constructed of rugged, black molded plastic, the TU-1000 is designed to withstand years of exposure to marine environments.

Low Cost Programmable Sonar Altimeter

The PSA-916 is a low cost, lightweight altimeter designed for diverse applications in the marine environment, providing high resolution altitude/range data, while simultaneously outputting data through a digital serial port.

A wide beam angle provides for reliable and accurate range measurements under the most severe operational conditions. To view more information click here.

Transponders XT-6001/TR-6001

The XT-6001 & TR-6001 Acoustic Transponders are glass instrument housings with general purpose transponder electronics. The XT-6001 is an expendable transponder, while the TR-6001 incorporates a burn wire release mechanism for ease of recovery. They can both be used for acoustic navigation or location marking.
