Sonardyne Release Transponder RT6-1000

The Release Transponder 6 (RT 6–1000) is a rugged and reliable coastal release transponder which uses our field-proven 6G Wideband®2 acoustic ranging and telemetry protocol. This means that RT 6 1000 can be tracked and released using any Ranger 2 6G USBL system or a low-cost deck command unit with remote dunking transducer on a 10 metre cable

Description

RT 6–1000 is depth rated to 1,000 metres making it the ideal choice for use in continental shelf waters. Field replaceable alkaline battery packs give a listening life of 18 months. A ‘screw-off’ release mechanism ensures a positive release action that overcomes any biological growth and all external parts are made of high strength plastics that provide excellent environmental corrosion resistance.

An NFC enabled reader can be used to program the acoustic identity of the RT 6–1000, run self-test functions, read battery status and load the release nut prior to deployment. The NFC link also provides the ability to enter RT 6-1000 into a storage mode when not in use, thereby significantly increasing the overall battery endurance.

An optional attachment for the RT 6–1000 is a rope canister that allows items left on the seabed, for example, tools, cables and salvage, to be quickly and easily hauled up. This works by mooring one end of the rope to the item on the seabed and the other end to the RT 6–1000 via the attached canister of rope. As the transponder ascends to the surface, high strength rope is deployed from the canister. This line can then be used to pull up the item directly or retrieve heavier tag lines
