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 capturing 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.
Eliminate blind searches normally performed by grapples, divers or ROV systems.
Save time by conducting wide sweep scans to track, mark and record GPS positions of interest

Detail of the Side-scan Towfish
The Side-scan Towfish system includes a Towfish outfitted with sonar, one topside control system,
45 feet connecting tether with strain relief cable and locking shackle
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.
