Amazon.com Product Description:
The Humminbird 383c Combo Fish Finder and GPS Chartplotter is an all-in-one fish finder for the recreational angler that offers incredible ease of use and GPS chartplotting. The 383c Combo is compact, but full of already built-in capabilities, with the ability to add advanced accessories, making it the perfect companion for your fishing outings.

The 383c Combo provides full GPS navigation, chartplotting and sonar right out of the box. This unit has a built-in 16-channel WAAS GPS receiver, and a four nautical-mile resolution UniMap of USA inland lakes, rivers and coastal areas. The 383c Combo uses DualBeam PLUS sonar, selectable between 20- and 60-degree beams, or simultaneous operation to deliver both wide coverage and better bottom definition up to 1,000 feet with a target separation of only 2.5 inches. This fish finder includes real-time sonar at up to 40 times per second, and Sonar Echo Enhancement sensitive enough to track a jig to over 40 feet. This unit's high-speed, micro-dynamic transducer is reliable up to 70 mph, and even includes water temperature and GPS speed.

The 383c Combo has a 3.5-inch, 256-color, sunlight viewable TFT LCD screen that sports 320 x 240 lines of resolution, and includes X-Press menus so you can access the most important controls with fewer button presses. This fish finder lets you select between TruArch for actual fish returns, and FishID+ with a selective target depth. This unit features a 2x, 4x, 6x and 8x zoom, fresh and saltwater set-up options for optimal performance in any environment, and an adjustable backlight for night fishing. With 750 waypoints, 20 routes, and 10 tracks with 2,000 points each, it is difficult to find a more complete system.

The 383c Combo comes as a Transom Mount with a tilt-and-swivel, quick-disconnect mount system, for either Gimbal or in-dash mounting. This unit measures 5.25 x 7.4 x 4 inches (WxHxD) as a Gimbal mount, or when in-dash mounted requires three inches of behind-dash clearance. Built with a fully gasketed and waterproof construction so that it will even float if something unforeseen happens, the Humminbird 383c Combo fish finder and GPS chartplotter is backed by a manufacturer's one-year warranty.
