The full-featured Fishfinder 363 Combo has an internal, 16-channel WAAS GPS receiver with omni-directional antenna for higher performance, and a built-in, four-nautical-mile-resolution UniMap of USA inland lakes, rivers and coastal areas that puts you on top of the hot spots. This unit utilizes DualBeam PLUS sonar that is selectable between 20- or 60-degree beams, or simultaneous operation to deliver wide coverage and better bottom definition that reaches a depth of up to 1,000 feet. While ideal for small spaces, the Fishfinder 363 Combo is big in performance, with real-time sonar that instantly captures the action under your boat, and Sonar Echo Enhancement that reveals the smallest details -- even your jig! All the information you need is displayed on a high-contrast, 16-level grayscale, four-inch LCD screen with 320x240 lines, which delivers an image of the bottom, fish, and structures with high visibility. This fishfinder has a high-speed, micro-dynamic transducer for optimum performance that is reliable up to 70 mph, and even includes water temperature and GPS speed. The Fishfinder 363 Combo is easy to control with X-Press Menus that access the most important controls with fewer button presses, and features TruArch for actual fish returns or selective fish ID+ with target depth, as well as one-touch zoom and bottom-lock to enhance resolution and separate fish from structure. This system also features a selectable large, easy-to-read digital readout with an adjustable backlight for night fishing, adjustable 2x, 4x, 6x and 8x zoom levels, and fresh and saltwater options for optimal performance in any environment. There is a Freeze Frame option that instantly pauses the action allowing you more time to see the details, as well as a Digital Flash View that delivers real-time, flasher performance. As an added convenience, this finder is ultra-compact in size, with an easy-on, easy-off mounting system that allows it to go almost anywhere. The Fishfinder 363 Combo is built tough with fully gasketed and waterproof construction so it even floats, and is assembled in the USA with a manufacturer's one-year warranty.
