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 simple On/Off switch, rugged spring assisted release mechanism, depth sensors and advanced power and gain controls if required. For deep-water towfish tracking, the Type 8129 DPT has a high power super directional transducer and 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.
