Capable of wide-beam scans, MarineNav’s Side-scan Towfish sonar and AUV sonar systems serve as a perfect complement to your ROV fleet, replacing the need for destructive bottom dredging or expensive dive teams. MarineNav wide-beam scan sonar systems are ideal for preliminary assessment of potential target areas identifying anomalies that can be reviewed and marked with geo-markers for future ROV exploration.

MarineNav’s portable Side-Scan Sonar Towfish system is a portable sonar that is easily transported and deployed to scan large areas of the seabed to spot anomalies, wrecks, ghost gear and other objects. The Side-scan Towfish sonar is connected by a strain relief rope and towed behind your vessel as it is in motion. Conduct a smooth survey of a target area simply by lowering or raising the sonar to a fixed depth, thus eliminating potential pitch and roll that may affect the quality of data capture. 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.
Plug the Side-scan Towfish connecting cable, power up the sonar topside case, and deploy the tow-fish over the side of a boat or from a Davit and start surveying an area in under five minutes.
The Side-scan Towfish topside includes a built-in option that allows users to choose from a DC power source (9-36V DC), an AC power source (120/240V AC), or access to a built-in battery source (built-in connectors for two plug-in Dewalt brand batteries).
Adjust sonar to 3 adjustable frequencies of 455Khz, 800Khz or 1.2Mhz. Higher frequencies provide more detailed seabed scans, while lower frequencies increase the sonar scan range. At 455Khz, the Side-Scan Towfish scans up to 235m (800 ft) on either side of your vessel.
Identify found objects and anomalies in real-time, and mark targets by creating touch-activated waypoints that record GPS coordinates. Review sonar sweep data frame-by-frame, fast forward, reverse and pause command functions allow users to focus on keyframes to assess possible anomaly targets. All recorded data is saved to the topside control system solid-state drive for future dive missions.
