'See' With Sonar

Whether you are surveying dive sites or submerged structures, shipwreck hunting, or conducting underwater research, “StarFish,” a new product recently launched in the UK, gives you the capability to 'see' underwater.

StarFish is a revolutionary high definition side scan sonar, which produces photo-quality images of the seabed. Built to a unique, innovative design StarFish is currently the smallest side scan tow fish on the market.

How does it work?  The device uses sonar to ‘see’ underwater to a much greater depth than the human eye.   It transmits small pulses of sound, which are absorbed and reflected back by the seabed and other underwater objects. The strength of each returned pulse together with the time the pulse travelled can provide us with a digital underwater picture. Side scan sonar is specifically used to view the seabed and any structures or objects laying on it.  The StarFish is called a ‘tow fish’ because it is used by towing it from a vessel.
