JW Fishers Sealion-2 ROVs are completely mobile underwater camera systems that are controlled from the surface and capable of staying submerged indefinitely. These ROVs are ideally suited to a variety of applications including pipeline inspections, river and ocean searches, dam surveys, oil and gas platform work, fish farming, and homeland security operations. They can dramatically reduce search time, as well as the risk and high cost associated with diving operations. Equipped with the RMD-1 remote metal detector the ROV becomes a high-tech search system capable of locating weapons, unexploded ordnance, pipelines, buried treasure, and other metal objects.

Both the SeaLion-2 and SeaOtter-2 come with carry case.

The SeaLion-2 is JW Fisher’s top-of-the-line ROV. It has four high-performance motors that make it faster than the SeaOtter-2. In addition, even more, thrust is available with a Power Boost feature that provides the ROV with an extra burst of speed when heavier currents are encountered. Other advantages are a 1,000-foot depth rated housing and the ability to operate with cable lengths up to 1,500 feet. Other features include front and rear-facing color cameras with pan and tilt. Illumination for the front camera is provided by two, fully adjustable, 2200 lumen LED lights. Lighting for the rear camera is provided by a ring of high-intensity LEDs.

System controls for the Sealion-2 are cleanly laid out in a high-impact waterproof case with an ultra-bright 15-inch flat-screen monitor built into the lid. Command of the ROV’s thrusters, cameras, and lights are managed with a compact hand-held controller. A wireless controller can also be used to give the operator even greater freedom. A gentle push on the vertical joystick propels the vehicle down into the depths, and a nudge on the horizontal sends the ROV flying over the ocean floor. The control panel has jacks and amplifiers which make it adaptable to the requirements of each job. A video output jack allows an additional remote monitor to be used simultaneously with the internal flat screen monitor. Other viewers can see the world below without crowding around the control console. An internal video amplifier adjusts picture quality to optimize the video for water clarity. Connect an external DVR recorder and make a permanent record of the underwater scene. With the internal audio amplifier, voice can also be recorded with the video picture.

Options available on the SeaLion-2 are cable lengths up to 1,500 feet, cable management systems, on-screen display for time/date/GPS/compass heading/depth/distance from the bottom, 2 color side camera (making a total of 4 cameras), auto depth control, auto distance from the bottom, control of ROV from a computer, an external DVR recorder, internal DVR recorder, video text overlay, manipulator arm, metal detector, scanning sonar, and spare parts kit (includes extra dome, thruster, light bulbs, etc.).

JW Fishers SeaLion-2 ROV Metal Detector

The JW Fisher SeaLion-2 is the next generation of JW Fisher very popular SeaLion ROV. More powerful than our SeaOtter, it has more options available and can handle 1,000-foot depths and operate with up to 1,500 feet of cable. With pan and tilt cameras in both front and rear, it is perfect for pipeline inspections, river and ocean searches, dam inspections, oil and gas work, fish farms, oceanographic research, an inspection of hazardous sites, and almost every type of underwater search or inspection operation. This ROV can dramatically reduce search time and the high costs associated with diver-based inspections. With the Sealion-2 your team can locate, inspect, and videotape a target without entering the water. The SeaLion can also narrow the search area so when divers are required, their time is spent on the target, instead of swimming grid patterns. When outfitted with a metal detector (JW Fishers RMD-1), the ROV can search for weapons, unexploded ordnance, pipelines, anchors, buried treasure, or other metallic objects.

Fishers ROVs are in use around the world by US and foreign military, state and federal agencies, search and rescue groups, universities, and many commercial diving companies. These high-performance underwater camera systems make public safety search operations less dangerous by assisting in the location of drowning victims and recovery of evidence. They help eliminate the need to dive in difficult or dangerous conditions, whether it be a low visibility environment or a dive beyond no-decompression limits.

The system is very user-friendly and with just a little practice time in a pool, the operator will have the SeaLion-2 moving effortlessly through the water. The ROV has a powerful and sophisticated four-motor propulsion system; two motors for forward and reverse, and two motors for vertical and lateral thrust. The high output motors are reversible and operate at variable speeds. An off-the-shelf PS2 controller (supplied) operates the system. A joystick controls the horizontal motors (forward/reverse and turning) – it can hover “in place” and rotate 360 degrees, and the second joystick controls the vertical motors (up/down and lateral movement). A wireless PS2 controller can also be used.

When a high water current situation arises where extra power is needed, a button on the controller increases the maximum power available by 30%; significantly increasing thrust.

The SeaLion-2 sends its video picture to a topside 15-inch high-resolution ultra-bright color monitor which is built into the Control Box cover. Video output in the Control Box allows an additional remote monitor to be used simultaneously. An adjustable video amplifier on the Control Panel allows operator adjustment of the video picture to optimize picture quality for water clarity. Optional built-in DVR or external DVR recorder can be connected to the Control Box to make a permanent record. The Control Box also contains an audio amplifier with an input jack on the Control Panel for audio recording.

The system has two color cameras (front and back) with 4mm wide-angle lens. The camera’s 90-degree tilt allows a full 145-degree vertical viewing. The camera’s 90-degree pan allows an additional 160 degrees of horizontal viewing. Both pan and tilt are controlled by pushbuttons on the PS controller. Camera selection, front or back, is operator selectable from the Control Panel. The Control Panel also contains an LCD readout that displays the overall status of the system. Illumination is provided by two 2200 lumen, high-intensity LEDs for the front camera and an “ultra-bright” LED cluster for the rear camera.

At 43 pounds the ROV is highly portable and very “user friendly”. With the optional spare parts kit, the ROV is completely field maintainable. JW Fishers SeaLion-2 ROV system represents a major breakthrough in cost/performance for a commercial-grade ROV. This high-performance system competes with ROVs more than twice the price.
