MarineNav portable Side-Scan Sonar Towfish system is easily transported and deployed for surveying large areas of the seabed to spot anomalies, wrecks, ghost gear and other objects. The Sidescan Towfish is connected by a strain relief rope and towed behind a vessel.
By simply lowering or raising the sonar to a fixed depth, you can eliminate vessel pitch and roll thus dramatically improving data quality. With GPS integrated into the topside case built-in screen, the Side-scan Towfish sonar can also be used as a chart plotter and is compatible with most marine map software, including Navionics, to provide detailed nautical navigation charts.
