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.
