IAvailable 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.
