Benefits of RT 6-HD for your operations
High WLL
The highest standard WLL of 2,500 kg of any of our transponders without any additional load amplification frames.
Choice of topsides
You can use our rugged Deck Topside or 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
Versatile
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.
Overview
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 use your vessel’s Ranger 2 USBL to deploy, track, locate and command the instrument – removing the need for a separate topside unit. If you don’t have access to a Ranger 2 USBL, our rugged and lightweight Deck Topside with an over-the-side dunker is all you need to both configure and command RT 6-3000s.
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.
RT 6-HD is configured with our iWand hand-held acoustic transponder test and configuration device.

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.
