Applied Acoustics Easytrak Lite USBL - available for rental, hire and ex-rental purchase from Ashtead Technology.

Easytrak, from Applied Acoustics, is an Ultra Short Baseline (USBL) underwater positioning and tracking system centred on a multi-element single transducer that transmits and receives acoustic signals to dynamic subsea targets, from which range, bearning and depth information can be determined. Devopled to meet the ever increasing demands for a highly efficient location device which is truly portable, straightforward to use and extremely stable, Easytrak offers a multitude of benefits for a wide range of marine positioning applications which include diver, ROV, AUV and towfish tracking, instrumentation positioning and release.

The Easytrak Lite has been designed for more permanent installation in a vessel's operation room or dry laboratory. The main transmit and receive electronics power supply and digital signal processing (DSP) hardware have all been mounted within a rugged enclosure for connection to a laptop or desktop PC. Connection is by USB cable, with the system software provided on CD.
