David Evans and Associates (DEA), an American consulting company, has received the SeaBat T51-R Integrated Dual Head (IDH) multibeam echosounder from Teledyne Marine. The system is intended for high-resolution seabed mapping in support of DEA's offshore survey projects.

DEA's engagement with RESON sonar technology goes back to the earliest SeaBat 9001 model. Over the decades, the firm has adopted each successive generation of RESON equipment. The SeaBat T51-R IDH is the newest model in this series.

The dual-head configuration of the T51-R IDH allows for a broader swath and enhanced data fidelity. Teledyne Marine, which acquired RESON in 2012, continues to produce and service the SeaBat line. This delivery indicates sustained demand for advanced multibeam echosounders in hydrographic and offshore engineering.

DEA has not revealed specific plans or schedules for deploying the new sonar. Nonetheless, the purchase signals the company's dedication to keeping its survey equipment at the forefront of technology.
