The ARC acoustic release canister retrieval system is designed specifically for use with Vemco VR2AR fish tracking receivers and Ascent Acoustic Releases. The ARC system brings the receiver to the surface, whilst leaving a rope attached to the seabed anchor to facilitate easy recovery of all mooring components.
The ARC system is made up of two main sections; the upper plate and the rope canister.
The upper plate attaches to the VR2AR mooring brackets and holds three 11” 8.4 kg buoyancy trawl floats. This section ascends to the surface when the VR2AR acoustic release is activated. One end of the rope (coiled inside the rope canister) is also attached to the upper plate.
The rope canister is attached to the release lug at the base of the VR2AR and the seabed anchor. Each standard canister holds up to 130 m x 4mm Dyneema rope or 65 m x 8mm Poly Prop rope with larger canisters available if required. As the upper plate ascends, the rope is spooled out of the canister allowing subsequent recovery of the seabed anchor.
The ARC system is built with robust, high quality materials, no moving parts and minimal fittings. This reduces failure points, minimises maintenance, whilst keeping total costs low. It is designed to present a low profile in high tide and current environments, and all parts can be removed for easy replacement and cost effective shipping.
