This year, Airmar celebrates its 40th anniversary as a leader in the advancement of ultrasonic sensor technology. Since 1982, Airmar has been committed to developing cutting-edge ultrasonic technologies and products. Airmar and its subsid- iary, Marport, have recently joined forces on a major project— the Trident Pro—Marport’s new multi-echo beam headline sounder for pelagic ? shing trawls. Expected to be released later this year, Airmar and Marport capitalized on both com- panies’ experience to build the Trident Pro: Marport developed the electrical system and software, while Airmar handled the mechanical design. Once on the market, Airmar will also be manufacturing the Trident Pro on site at their headquarters in

Milford, New Hampshire. Mounted remotely on the trawl gear headline, the Trident Pro relays detailed echogram images from four individual sonars to the vessel via acoustic link: one depth range of 1700 m and is powered by a lithium-ion battery image from directly below, two from each side of the ? rst, rather than a power cord tethered to a vessel. The wide range and one from directly above. The ranges of each echogram are of unique echogram data provided by the Trident Pro enables con? gurable from 20 meters to 160 meters, so the Trident Pro it to serve as an important complimentary or backup tool for can detect the ? sh passing above and below it, the ? sh inside the conventional third-wire headline sonar used by most pe- the trawl, and the footrope. The fully remote Trident Pro has a lagic vessels.
