Frequently Asked Questions

How far can I see?

Naturally, the clearer the water, the farther you can see. As a general rule, the camera can see twice as far in water as the human eye. Generally, if you can see 3 feet down in the water, you will be able to see approximately 6 feet in front of the camera. However, water bodies vary in water clarity and other characteristics. For studying underwater structure, 2 feet of visibility is sufficient for viewing, though in very clear water, it is possible to see up to 30 feet or more.

When do I use the SR lights?

The Spectral Response (SR) lights in your MAV camera are designed for use in low-light conditions. Turn the lights on for enhanced visibility in low light. While the lights will yield additional dark water visibili- ty, they will never allow you to see as well as during the day, or in very clear water. With lights on, you will see a video image similar to that in front of your car’s headlights. Spectral Response lights, though, actually absorb and filter out many of the suspended underwater particles that may otherwise obscure viewing visibility during low light conditions.

How do I steer the camera?

For viewing in the direction of travel, attach the front-viewing Stabilizer Fin to the camera housing. Slowly troll (less than 2 mph) or drift along the structure you intend to view. With fin attached, the camera will face in the boat’s direction of travel. If you’re facing and moving forward, so will the cam- era; it will show you the underwater terrain in front of you. The Stabilizer Fin always keeps the camera tracking straight, so long as you’re moving.

Can I splice the camera cable to obtain more length?

No. Attempting to splice in additional cable violates the waterproof integrity of the camera and cable. This will void your warranty.

How fast can I troll with my camera?

It depends on depth, and also on the length of cable you have out, which determines water resistance or “drag.” As depth (cable length) and boat speed increase, drag will increasingly cause the camera to move away from the bottom. At slower speeds, it is much easier to watch the underwater terrain. For optimal viewing, we recommend traveling less than 2 miles per hour. Remember, the slower you go, the more detail you will see. Also, the faster the bottom depth changes, the more rapidly you will need to move the MAV cable.

Can I use my MAV in saltwater?

Yes. All Aqua-Vu cameras are saltwater-rated, constructed with stainless steel hardware and materials that are impervious to corrosion.

Will my unit work in subfreezing conditions?

Aqua-Vu systems are designed to operate at temperatures ranging from -10 to 120 degrees F.

How wide is the camera’s angle-of-view?

Your camera lens has a viewing angle of 92 degrees. At 4-1/2 feet in front of the camera you will be viewing an image approximately 6 feet wide.
