Teledyne Marine Launches Portable Variant of SeaBat T51

Teledyne Marine has launched the SeaBat T51-P, a new variant of its SeaBat T51 multibeam echosounder that combines the system’s sonar performance with a portable processor designed for use in exposed marine environments.

The SeaBat T51-P pairs the T51 sonar with Teledyne RESON’s portable sonar processor (PSP), which is IP-rated and splash-proof. This makes the system suitable for surveys from small boats and dinghies without enclosed cabins, where equipment may be exposed to water. The processor can accept 24 V DC power, allowing it to be connected to a battery and supporting use in a wider range of survey environments.

At the heart of the system is the SeaBat T51’s 800 kHz performance, which delivers full-swath coverage of up to 170 degrees. Designed to provide high-quality, detailed survey data, the T51 helps users identify seabed features clearly while reducing the time spent processing and cleaning unreliable data after a survey.

The T51-P also retains the features from the established SeaBat product range, including automated sonar controls, adaptive gates and vertical detection mode. The SeaBat tracker system automatically adjusts the sonar settings to help users collect the required data with less manual intervention. Adaptive gates follow changes in the seabed, helping to capture features such as sand waves, depressions and seabed obstacles, while vertical detection mode supports the identification of vertical structures, including quay walls, making it particularly useful in harbor surveys.
