Side Scan Sonar Surveys

Divetech Ltd also offer side scan sonar surveys using our Tritech Starfish 990 F system, easily deployed from small boats and a cost effective solution to wide area searches

Side Scan Sonar SurveysThe 990F is the ultimate high resolution StarFish side scan sonar for extreme image definition and target detection. Based on the popular and proven 450F design, the StarFish 990F uses high frequency 1MHz acoustic chirped pulses with a 0.3 degree horizontal beam width to produce the most defined and clear images from any StarFish system. With a 35m range capability on each channel (giving 70m total swathe coverage), the StarFish 990F is the ideal tool for high resolution surveys in ports & harbours, academic research, inland waterways such as rivers and canals, and SAR (Search And Recovery/Rescue) operations.

Measuring less than 15 inches long, the StarFish 990F sonar is the smallest towed side scan sonar available. The system is independent of the boat, requiring no fixed installation and making it easy to transport and operate from any vessel. The topside controller connects to any Windows PC or laptop via USB connection for easy operation by a single person. Simply deploy the sonar by hand and tow from your boat to capture and record real-time images of the seafloor below.

StarFish Seabed Imaging Systems are ideal for shallow-water survey applications in water depths up to 50m/175ft.
