cessor. The four vectored thrusters allow horizontal motion in any direction, and the ability to rotate-in-place. Vertical power is also increased, with three thrusters for diving and lifting. The unique vertical thruster placement also provides the ability to adjust pitch and trim of the ROV. The SeaLion-3 is depth rated to 1000 ft. with the option of up to 1500 ft. of tether. The SeaLion-3 has two full HD video cameras and recording capability. The new topside console has two moni- tors for viewing and controlling the ROV. The top monitor is a large 15-in. screen for viewing the 1080p videos from

JW Fishers Mfg. was founded by the late Jack Fisher in the either screen. The solid-state internal storage can record over 1960’s. Handheld underwater metal detectors were the basis of 200 hours of HD video. The SeaLion-3 has a full comple- foundation for the brand, but quickly advanced into a full ar- ment of sensors and attachments: an inertial measurement ray of underwater search equipment. Today the extensive line unit (IMU), a depth and water temperature sensor, front and of product includes hand-held and boat-towed metal detectors, rear high-intensity LED lighting, altitude sensor, an optional magnetometers, underwater HD video systems, ROVs, sonar gripper attachment, and optional sonar. The advanced IMU systems, acoustic pingers & receivers, pipe & cable trackers, a and depth sensor on the SeaLion-3 allow for automated ‘hold’ sub bottom pro? ler system and the Pulse 8X underwater metal modes of operation, during which the ROV can maintain its detector recognized #1 by US Homeland Security. own depth or altitude, and magnetic compass heading, with-

JW Fishers once again has raised the bar in 2023 by intro- out operator control. The operator can concentrate on driving ducing the SeaLion-3 ROV with 2x as many thrusters for and searching with the ROV, without having to worry about horizontal movement, and is twice as powerful as its prede- maintaining depth, heading or other navigational concerns.
