Starfish Sidescan Sonar

Starfish Sidescan Sonar

The StarFish range has gained worldwide recognition as the most compact, affordable, towed side scan sonars for the professional underwater survey industry. 

These compact side scan sonars measure less than 15” long, making them extremely portable, allowing them to be deployed from even the smallest of vessels, and in shallow water environments. All the towed StarFish sonars have the same physical size and shape based on their signature three‐fin hydrodynamic design. The unique design improves stability of the sonar during towing, and ultimately helps to ensure the system produces the highest quality sonar images possible. 

Utilising the latest in advance CHIRP (Compressed High Intensity Radar Pulse) acoustic technology StarFish sonars have the ability to detect small closely spaced targets at far greater distances than conventional single frequency, monotonic systems. 

StarFish systems have been designed to be ‘plug & play’, connecting to your PC/laptop via a top‐box with USB connection. The top‐box allows the sonar to be powered from both AC or DC power supplies. The intuitive StarFish Scanline software, designed for Windows operating systems, has an easy‐to‐use interface. With helpful ‘Wizards’ to get you started, you’ll be up and running in no time. 


Starfish 990F

The ultimate high resolution StarFish side scan sonar for extreme image
definition and target detection. The sonar uses a high frequency 1MHz
CHIRP transmission with extremely narrow horizontal acoustic beam to
provide the sharpest, most defined images from any StarFish system.
With 35m range capability on each channel (70m total swathe coverage),
the sonar is ideal for high resolution survey in ports & harbours, inland
waterways such as rivers and canals, and excels when used for SAR
(Search And Recovery/Rescue) operations. The sonar also has an inline
connector to allow the cable to be swapped or replaced on site. Get Quote

Starfish 452F

Building on the success of the original StarFish 450F, the new
StarFish 452F sonar has TWICE (x2) the image resolution
compared to the 450F model, while continuing to offer wide range
imaging capability of 100m per channel (200m total swathe
coverage). The sonar uses a mid‐band 450kHz CHIRP transmission
to offer the greatest combination of ranging capability and image
resolution from a single frequency system. The sonar also has an
inline connector to allow the cable to be swapped or replaced on
site. Existing owners of StarFish 450F & 450H systems can upgrade
to the new StarFish 452F should they desire higher definition
sonar imagery. Get Quote

Starfish 450F

The original StarFish 450F sonar offers a powerful, yet affordable, entry‐
level side scan sonar system for shallow water survey work. Since its
launch, the StarFish 450F has gained worldwide recognition as the most
portable, affordable, towed side scan sonar on the market.   Powered by
a 450kHz CHIRP transmission, the 450F provides wide range sonar
coverage up to 100m/ 300ft per channel (200m/ 600ft total swathe)
with good, clear image definition Get Quote

50m Tow Cable

StarFish Seabed Imaging Systems are now shipped with a 20m towing cable as standard. However, with the introduction of the 452F and 990F sonar heads, their inline sub-sea 'Impulse' connector allows the towing cable to be interchanged.

The 50m cable option is a StarFish accessory, offered to provide flexibility on larger vessels. Where a large amount of cable is required on deck, the 50m option allows the system to be installed while still leaving sufficient cable length for flying the StarFish. Get Quote
