Towed multi-aperture side scan sonar
Engineered for: Towfish
Equinox is an integrated, towed multi aperture sonar that delivers improved area coverage rates for mine countermeasures (MCM) and hydrographic operations. It offers unrivalled stability, position accuracy and results in real-time. At its core, is our Solstice multiple aperture sonar delivering imagery of the highest quality possible from side-scan sonar enabling detection and classification of seafloor objects across the whole swath.

Why Equinox is perfect for your operations
Low logistics and high coverage rates make Equinox the perfect choice for UXO and site surveys pre-installation of renewable energy sites
High-quality data provides you with confidence during your MCM surveys, ensuring actionable insights are at your fingertips
Never miss any details again with crystal clear data swaths that grant you unrivalled imagery for your research missions
Equinox combines our state-of-the-art SPRINT INS, Mini-Ranger 2 USBL and Solstice Multi Aperture Sonar (MAS) mounted on EIVA’s (a Sonardyne Group company) renowned ScanFish 3D, a steerable remotely operated towed vehicle (ROTV). EIVA’s NaviSuite Kuda user interface is used to plan, autopilot and display the data in real-time.
Producing stunning accurate pictures, it’s ideally suited for vessels of opportunities or unmanned surface vessels delivering hydrographic, archaeological, search, salvage, unexploded ordnance, and mine countermeasure missions.
The ScanFish 3D is a trusted ROTV and thanks to its inherent stability the ideal platform to operate Solstice from. At a total weight of 220 kg in air, Equinox can be easily mobilised.
Unlike towed Synthetic Aperture Sonar (SAS) systems, Equinox offers an affordable lower-logistics alternative still capable of providing high area coverage rates. By combining leading navigation and positioning using our Mini-Ranger 2 USBL and SPRINT INS, imaging data is geo-referenced with an accuracy that’s unrivalled for these types of applications at this price.
Planning a mission is easy. Using NaviSuite Kuda software you can define your sailing route and run-lines by simply selecting the area you would like to cover. During the mission, NaviSuite Kuda continuously updates the vessel and ScanFish 3D position in real-time.
Equinox also provides real-time geo-rectified waterfall, mosaics and DTM maps and the user interface tools that enable an operator to mark and process objects, including automatic target recognition using AI.
That’s not all, ScanFish 3D can carry heavier payloads and there is room in the fibre cable to include additional payload sensors such as gap fillers. Equinox users can count on improved Probability of Detection and decreased Probability of False Alarms improving the efficiency of your mine counter-measures, archaeological, search and salvage missions.
