Description

The Types 8124, 8126 and 8129 DPT’s are full sized transponders designed specifically for seabed deployment or large target tracking. Available in 3,000 metre rated omni- directional or directional transducers, DPTs are equipped with a rugged spring assisted release mechanism, depth sensors and advanced power and gain controls if required. For deep-water towfish tracking, the Type 8129 DPT is a midi-sized unit with a high power super directional transducer that is depth rated to 7,000 metres. DPTs support Sonardyne Wideband™ signals, tone frequencies and all HPR 300/HiPAP® channels. DPT also supports Sonardyne command and control options. Also available is the Type 8132 DPTi which is fitted with internal inclinometers to accurately monitor riser angles (see separate datasheet). The DPTi can also be used with an external inclinometer unit to monitor flex joint angles. Key Features
