Easytrak Vesta USBL, Model EZT-2666
The Vesta USBL is an entry level tracking system and the most compact version of the applied acoustics’ range of USBL systems. Ideally suited to small vehicle operations or diver tracking, Vesta is a cost effective system for monitoring targets of up to 1000m range, and features a number of enhancements that allows the system to punch above its weight.
