Acoustic technology enables ropeless fishing system

EdgeTech, a specialist in high resolution sonar imaging systems, acoustic release systems and underwater technology, has announced the introduction of its new Ropeless Fishing System.

EdgeTech’s development team have been working to come up with an embedded acoustic release technology to eliminate the need for dahn lines connecting a surface buoy to bottom fishing gear.
The system has been designed from the ground up with fishermens’ input with the intention of alleviating possible whale entanglement and other negative effects of seafloor-to-surface fishing and trap lines.
The EdgeTech 5112 Ropeless Fishing System is designed for the rough-and-tumble handling of shallow water and small boat operations. Expanding the extensive line of reliable acoustic release products and utilising the same proven Push-off Release Transponder (PORT) technology, the EdgeTech system is suited for those applications that require a robust, yet shallow water, acoustic release enabled ropeless fishing package.
The unit can be deployed in water depths down to 500 metres and handle a load of 225kg while remaining underwater for up to one year (or two years on lithium batteries).
According to Edge Tech, with its unique nickel aluminium bronze alloy construction, it can withstand even the harshest shallow water environments providing corrosion resistance like none other.
The system has capacity to communicate with the catching vessel to provide position, battery life and tilt status data, as well as release confirmation and temperature.
The EdgeTech Trap Tracker application for Android and IOS platforms records all data, plots the trap and trawl locations and uploads the positions in real time to a Cloud data base so that other fishing vessels can see where gear is located to avoid setting over other strings of traps.
The system will tolerate harsh handling on the vessel and unfavourable conditions under the water. The acoustic coding structure allows for more than 1 billion unique codes, making it the most secure acoustic release ever produced.
