Teledyne Marine Launches SeaBat T51 Integrated Dual Head Systems To Boost Survey Efficiency

3/2/2026

​​​​

​At Oceanology International (Oi26), Teledyne Marine will introduce new additions to its SeaBat T-Series sonar portfolio, offering Integrated Dual Head (IDH) capability to the SeaBat T51 multibeam echosounder series, extending dual head performance to both surface vessel and deepwater ROV deployments. 

Already proven on the SeaBat T20 and T50 platform, the Integrated Dual Head functionality will now extend to the respected SeaBat T51-S and T51-R, the industry’s preferred choice for mapping projects that require the finest resolution. The SeaBat T51 is the only multibeam echosounder featuring an array designed for 800kHz; this unique design allows users to map the highest resolution without sacrificing swath width, eliminating the traditional trade-off between resolution and efficiency.

With the addition of the Integrated Dual Heads, survey teams can benefit from increased mapping efficiency and acquire more high-resolution seabed data in less time, delivering valuable reductions in operational time and cost.

The rack-mounted SeaBat T51-R IDH is designed for installation on surface vessels, while the SeaBat T51-S IDH​ is optimised for ROV deployment and is depth-rated to 6000 metres. The Integrated Dual Head processor combines two processors into one, meaning operators benefit from weight and space savings, while achieving wider swath coverage, improved along-track data density and simplified installation and operation.

Engineered to support both subsea and surface survey operations, the new Integrated Dual Head comes with SeaBat’s full-rate dual head feature as standard. This is the simultaneous full-rate operation of two sonar heads within a single system, removing the need for traditional staggered pinging and allowing operators to maintain survey speed while maximising data density and coverage. 

“Integrating dual heads into a single processor significantly improves survey performance while reducing system complexity for operators” said Pim Kuus, Senior Hydrographer and Product Manager of Instruments & Imaging at Teledyne Marine. “The full-rate dual head capability increases along-track data resolution, capturing more measurement points throughout the direction of travel and allowing for more detailed seabed mapping. We’re looking forward to showing off the new variant at Oi26.” 


The SeaBat T51 IDH system will allow users to capture the finest detail across the full swath, including details on or around a pipeline, free spans, small boulders, and fine scaled bathymetry. Visitors to Oi26 will be able to see this for themselves, as the SeaBat T51-R Integrated Dual Head system will be showcased in action during liveReserve a seat now.

The SeaBat T51 Integrated Dual Head systems are available for order now.
