Tritech Launches Horizon Multibeam Echo Sounder
Tritech is pleased to announce the launch of Horizon, an advanced product for multibeam seabed surveys.
Horizon is a multibeam echo sounder (MBES) comprising a sonar head, surface processing unit and control software. Housed in a single compact and robust unit, it uses the very latest advances in acoustic time delay beamforming techniques to deliver high-quality survey data at an affordable cost.
In shallow water, Horizon can be mobilised on a vessel to gather survey datasets at depths down to 120m. For deep water survey operations the system can be deployed on an ROV platform. Horizon operates at a frequency of 240 kHz and has a wide swath coverage of 120 degrees. Where required, two Horizon sonar heads can be easily linked together to form a dual-head system for maximum and uninterrupted swath coverage. Extremely fast ping rates of up to 100Hz, combined with pitch correction, allows Horizon to be used for higher speed survey operations without compromising along-track data density and resolution.
Horizon software real time waterfall display
The Horizon system accepts motion sensor data input to give a fully corrected sonar image, which can be viewed as an online waterfall display. This unique method of visualising the raw data provides the user with an instantaneous non-digitised image of the seabed – ensuring all features of interest are observed.
Data gathered by Horizon is exported in real-time via a network connection to third-party software packages such as Hypack/Hysweep and PDS2000.

Tritech’s Sales and Marketing Director, Maurice Fraser, commented on the launch:
“The addition of Horizon to Tritech’s multibeam product portfolio affirms our commitment to deliver new and innovative products to the market. Horizon offers excellent acoustic resolution with multiple applications for seabed survey and inspection, complements our successful Eclipse and Gemini multibeam sonars, and cements our position as one of the major multibeam sonar manufacturers in the world.”
