Easytrak 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, bearing and depth information can be determined.
As a full system package, Easytrak has been specifically designed to overcome the difficulties of tracking underwater targets such as divers, ROV’s, AUV’s and tow-fish which operate out of sight beneath the water surface. As the name suggests, rapid deployment and ease of operation ensures that even novice users can commence tracking within minutes of set up. The innovative, compact design incorporates an impressive amount of features, providing stable and accurate tracking for a variety of subsea tasks.
The ‘family’ of systems manufactured cover applications from professional high accuracy positioning to low cost quick deployments. They can be supplied with a range of target beacons from small lightweight units that can be charged from a mobile phone, to long-term deployable transponders incorporating acoustic release functionality.

Four commercial versions of the system are available; the rack-mount, vessel based Nexus 2; the compact Nexus Lite or entry-level Alpha, and the Alpha Portable that has a display screen and keyboard housed in a marine grade splash-proof enclosure.
The Nexus 2 is the most recent rack-mount model now available with a choice of transceivers, omni-directional or directional. In addition to tracking traditional ‘tone-burst’ beacons, Nexus also tracks Spread Spectrum beacons that offer increased performance.
A military grade system is also available, the Easytrak M-USBL 2671
