The Heavy Duty Acoustic Release Frames have been designed as optional extras for Sonardyne's popular Type 7409 Oceanographic Release Transponders (ORTs) and Type 7710 Deep Oceanographic Release Transponders (DORTs).

The Type 7869 release frame increases the Safe Working Load (SWL) of a standard ORT or DORT to 7½ tonnes (at 4:1 safety factor) with a breaking load of 30 tonnes.

The release frame can be fitted without any modification to the acoustic release itself and is easily assembled in the field. Manufactured from high strength steel which is galvanised and powder coated, the releases offer excellent corrosion resistance for long term deployment. This can be up to 3 years when the ORT is fitted with a lithium battery pack. Depth rating is solely dependant upon the acoustic release being used; 2,000 metres for an ORT.
