Reson 8125-H Multibeam Echosounder - Available for rental, hire and ex-rental purchase from Ashtead Technology.

The new SeaBat 8125-H combines the 8125’s celebrated sonar head with an advanced data processor. Using 256 dynamically focused receive beams, the SeaBat 8125-H cuts a 120-degree swath across the seafloor. The result? Sea-floor detection is reliable, depth resolution is a crisp 6mm, and you can view backscatter intensity in real time on the sonar display.

The 8125-H’s advanced autopilot makes sure you cut the right swath first time every time, so you can focus on your survey data. And roll stabilisation enables you to complete your survey in inclement weather with no loss of accuracy.

For ROV deployment, you can optimise the 8125-H’s high-speed data uplink with a fibre-optic interface.
