Description
The Computing and Telemetering
Transponder (Compatt) is a
microcomputer controlled subsea
transponder used for acoustic
navigation and positioning.
The Type 7802 Compatt Mk4 is the
Low Frequency (8 - 16 kHz) version
of Sonardyne’s fourth generation
family of transponders built to

such as underwater measurement,
remote control and monitoring,
where ranges of up to 10km can be
achieved in adequate water depth.
