Once 002-2again Synt 3000 has been used with great success.
The British company Sonardyne, www.sonardyne.co.uk, the world market leader in underwater positioning has commissioned Resinex to produce high performance floatation collars for its range of subsea acoustic transponders.

The smaller floatation collar is able to support transponders to depths of 500 metres while the larger float is designed for transponders operating at depths of 3000 metres. The floats were made with Synt 3000 Resinex and depth tested to 3000 metres at the Resinex Marine Research Centre.
