See what's going on beneath the surface (or the ice) with the micro Stealth 4.3 Underwater Viewing System from Aqua-Vu. The system makes a great fish finder, taking the guesswork out of the activity by showing you exactly where the fish are and allowing you to see when they take the bait. It can also be used for general marine life observation or salvage activity. Infrared lights alongside the camera lens illuminate the scene, and the included fin can be set to point the camera up or down, facing forward, rearward or sideways. The micro-camera and its depth-marked 50' tether are designed for submersion, while the smartphone-sized LCD monitor is meant to stay topside. The built-in lithium-ion battery provides six hours' runtime on a fresh charge.
