History of Rope-less Fishing with ARC-1XD
2005
ARC-1XD Scientifically Validated
First validated in 2005 in the Channel Islands for large under-water gear retrieval.
2011
First Pilot in a commercial fishery
New South Wales and the first rope-less fishery
Australian lobstermen test out the ARC-1XD technology for ship strike mitigation near Sydney. (2011)
Since 2013
Commercial Use in Australia
Validated by independent auditors in New South Wales, Australia becomes the first to commercially use the ARC-1XD. (2013)
2018
North American Pilot Projects Proceeding
North American Pilots
Near extinction of the Northern Right Whale has triggered urgent action in North America. Pilot projects lead by DFO are to start in Canada in Spring 2018. US Projects possibly following.

Product Description
The ARC-1XD ‘extended duration’ acoustic release is specifically optimized for the operation and remote recovery of large inventories of commercial fishing gear. The ARC-1 acts as a release mechanism for an anchored buoy (any anchor weight), thus eliminating surface equipment and gear from the vertical water column. It provides the operator with real-time status feedback, and then uses a very fast acting mechanism to reliably recover the payload. The ARC has been field tested, validated and used continuously since 2003, and stands as the worlds only fully-functional rope-less fishing system. The ARC-1XD is unique in that it not only prevents whale entanglements but also offers business advantages to fishermen who use it. The ARC also offers new innovation in the way gear is marked and regulators are able to track and control traps (Rope-less fisher app).
Patent #US 7138603 B2
How it Works
The ARC-1XD and payload are fastened to the Pot/Trap. From the vessel the unique serial is called from a surface station (STM). From the STM, the release signal is given via a transducer either in the hull of the ship or over-the-side of the ship. The burn-wire is burnt and the lever arm releases the anchor weight. Allowing the payload/buoy to surface along with the ARC-1XD.
Release Mechanism Up-Close
2) Sent to the Surface Station
3) Surface Station Relays electronic command into Sonar ping
4) Ping produced by tranducer attached to surface station
5) Ping reaches the ARC
6) ARC "talks back" with status update
7) Second Ping triggers release
8) High voltage but low amperage charge sent through nickel chromium burn wire
9) Burn Wire disintegrates immediately
10) Lever Arm is freed from anchor weight
11) Buoy and floats to the surface for grappling
Fishery Integration
Hands on Class
Desert Star offers a three day hands on class for fishermen interested in pilot programs. The class covers ARC-1XD use, maintenance and best practices, with hands on training provided by a Desert Star technician.
Boat Specific Integration
All required/desired equipment related to the function of the ARC-1XD will be installed and tested by a Desert Star technician. This includes in-hull transducers, surface stations, new deck computers, optional gps head sensors and any other relevant system.
At-sea fine tuning and strategic fishing
After the three day class and at-sea fine tuning, Desert Star will provide on-site support for an agreed upon amount of time. This support is meant to help fishermen fine tune their new technology, troubleshoot should any problems occur, and help fishermen fine-tune their fishing strategy to fish smarter with the ARC-1XD.
Arm
The release is armed prior to use by inserting a small length of nickel-chromium wire which constrains a lever.
Test and Deploy
The package is now submerged next to the boat, or placed in a water filled test tub on deck. A command from the deck unit confirms contact by interrogating the unit specific serial ID via testing the device and registering the GPS location. Anchor weight is attached to the bottom while a buoy or floatation (up-to 80lbs float weight) is attached on the opposite end of the top. The instrument package is then dropped to the sea floor and the boat can proceed.
Interrogate
As the boat approaches the GPS location, the deck box interrogates and ranges to the ARC-1. battery. Status information is returned and the distance measurements are used to position the boat close to or directly above the release. Even if an instrument moved, ranging allows the boat to be positioned for rapid recovery – in particular useful in heavy seas.
Release
Upon command, the ARC-1 energizes the nickel-chromium wire with a safe low-voltage but very high current pulse is generated from standard 9V and/or AA batteries.. It vaporizes instantly, the lever opens and the instrument package or a buoy rises to the surface. The ARC-1 also confirms released status.
