Benefits of RT 6-6000 for your operations
The highest standard WLL of 2,500 kg of any of our transponders without any additional load amplification frames.
If you've got access to a Ranger 2 USBL system on your survey or research vessel then you have everything you need to control your RT 6-HD.
RT 6-HD is more than just an acoustic release. It can be tracked with our Ranger 2 USBL making relocating and recovering it fast and simple.
Acoustic release transponders are a vital pieces of ocean equipment; relied upon by energy, defence and science users to moor valuable equipment strings for years at a time, and when commanded to do so, reliably return equipment and logged data to the surface.
Transponders need to be tough, reliable and easy to work with. The RT 6-HD meets these requirements.
Part of our new range of acoustic releases, RT 6-HD combines the extensive mechanical design track record with the flexibility of our 6G platform, resulting in enhanced battery life and perhaps most significantly, compatibility with our Ranger 2 USBL system.
With RT 6-HD you can for the first time use your vessel’s Ranger 2 USBL to deploy, track, locate and command the instrument – removing the need for a separate topside unit.
For users without access to Ranger 2 USBL, a portable dunker unit is available to command RT 6-HD.
With a WLL of 2,500 kg (at 4:1), twice that of our RT 6-3000 and RT 6-6000, RT-HD is designed specialist heavy lift application scenarios such as deep water construction and salvage.
RT 6-HD is also our deepest rated acoustic release transponder at 7,000 m. Excellent corrosion resistance is achieved by using super duplex stainless steel for the housing materials.
On the back deck prior to deployment, RT 6-HD is configured with our iWand hand-held acoustic transponder test and configuration device.

RT 6-HD case studies
Deep water structure installation – made easy
Our Gyro Compatt 6 is a great way to simplify structure installation operations in all water depths. Using our Gyro Compatt 6 helped offshore contractor China Offshore Fugro Geosolutions (COFG) performed smooth structure installations during the latest phase of the deep water Liuhua field in the South China Sea.
Deploy, retrieve, repeat – made easy with RT 6 acoustic release
Shallow water isn’t any less demanding than deep water. DynamOcean operates in tidal estuaries with fast-flowing water and ever-changing environmental settings. Using our acoustic releases and underwater positioning technology they were able to reliably deploy and retrieve their ADCP sensors.
