StarFish 990F XD
Towed Sidescan Sonar
Towed StarFish allow quick and easy, single person deployment making them ideal for shallow water survey work and Search And Rescue applications. The innovative full-length tri-fin design provides a stable platform for improved image capture and the single tow-line cable keeps setup and operation as simple as possible. With a 0.3° horizontal beam width and 1MHz CHIRP operation, the StarFish 990F XD offers extremely high-resolution imaging and a focused swathe width of up to 70m.
Description
STARFISH 990F XD
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 XD uses high frequency 1MHz acoustic 'chirped' pulses with a 0.3° 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 XD is the ideal tool for high resolution surveys in ports & harbours, academic research, inland waterways such as rivers and canals, and excels when used for SAR (Search And Recovery/Rescue) operations.
Measuring less than 15 inches long the StarFish 990F XD sonar is small enough to be transported in your rucksack. Lightweight and quick to deploy by hand, the 990F XD towed system is independent of the boat requiring no fixed installation which makes it easy to transport and operate from any vessel.
High definition 1MHz CHIRP operation, towed StarFish ideal for survey and Search And Rescue applications.
