Our range of subsea floatation collars enable acoustic navigation and positioning transponders to be deployed, moored on the seabed and then recovered to the surface.

The floats are compatible with all our latest generation Compatt 6, AMT 6 and DPT 6 Wideband transponders as well as previous generation Mk 5 Compatts. They can be used with directional and omni-directional transducer types.

Manufactured from high performance materials appropriate to the required depth rating, each float assembly comes in two halves and is clamped around the transponder using stainless steel fixings made of super duplex stainless steel.

Bright colours make sure good visibility, either when subsea and viewed from an ROV’s camera or when floating on the surface prior to recovery.

Once on the surface, the floatation collar is designed so the transponder floats in a downward position ensuring the acoustic transducer is kept submerged.

This can assist with relocating the transponder using a vessel-based acoustic positioning system and also protects the acoustic transducer during recovery.
