It has been specifically aimed at carrying out complete test and set-up of Compatt 5 and DPT transponders. All acoustic functions, sensors and the release mechanism can be tested prior to deployment. The unit is battery powered and environmentally protected to IP65 and is therefore suitable for operation in most conditions.

The DTU is capable of transmitting and receiving a selection of both Sonardyne WidebandT and Tone acoustic signals in order to fully test the Compatt 5's and DPT's functionality.
It replaces Sonardyne's ANT as the primary test equipment for Sonardyne and other acoustic instruments, both on deck and in the workshop.

The LCD display is designed for reading in sunlight and is back-lit for use in low-light conditions.

Its rechargeable Lithium-Ion battery lasts for at least eight hours of normal testing.

The results of tests performed are stored internally in a test record which can be uploaded to a PC via USB for long-term storage and hard-copy printout as a permanent record of the tests.

Firmware upgrades for Compatt 5 can be stored in the DTU and downloaded to Compatts on deck.

Initially programmed to perform acoustic and cable-connected tests on Compatt 5 or DPTs, the DTU firmware can be upgraded to cover many other acoustic instruments.
