StarFish 452F Towed Sidescan Transducer Head

Product Code : BP00180



Based on the popular 450F design, the StarFish 452F brings even higher definition imagery to your PC. With half the horizontal beam angle of 450F(for twice the resolution) and our advanced digital CHIRP acoustic technology developed from the professional underwater survey industry, StarFish 452F produces crisper and cleaner imagery at ranges of up to 100 metres on each channel (200m total swathe coverage). It competes with many larger commercial systems produces spectacular images of the seabed, and includes intuitive software with a variety of data export options.

The compact hydrodynamic full body three-fin design improves stability of the sonar while it’s being towed which in-turn helps improve the quality of images it produces. The sonar also incorporates an inline connector to allow the cable to be swapped or replaced on site. Additional cable lengths are also available to help you choose the best towing solution for your needs.
