The full-featured 737 utilizes QuadraBeam sonar that is selectable between 20-, 60-, or 90-degree beams for the widest possible coverage and better bottom definition, with depth capabilities of 160 feet in QuadraBeam, or up to 1,500 feet in DualBeam. This allows you to locate fish not just below your boat, but to the left or right of your boat as well. While ideal for small spaces, the 737 is big in performance, with real-time sonar that instantly captures the action under your boat at up to 40 times per second, and Sonar Echo Enhancement so sensitive it reveals the smallest details -- even your jig! All the information you need is displayed on an ultra high-contrast, five-inch LCD screen with 640x320 lines, in 16-level grayscale for crisp images 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 speed capable. The 737 also has full GPS trackplotting capability to show position, mark hotspots and easily find your way home, as well as PC-connection capability to save and manage waypoints and upgrade internal software. The GPS capability has a full-screen trackplotter and a 3D track and split-screen sonar track with an adjustable split. Easy to use, this fishfinder includes advanced upgrades that are plug-and-play compatible, from the GPS receiver, to the SmartCast wireless sonar link and PC connection accessories. It even includes a memory-card expansion slot for Digital Screen Snap Shot or optional cartography.

The 737 features real-time flasher performance, Bottom Lock to enhance resolution and separate fish from structure, one-touch zoom with 2x, 4x, 6x and 8x zoom levels, and X-Press Menus so you can access the most important controls with fewer button presses. This fishfinder has both fresh and saltwater set-up options for optimal performance in any environment, and lets you choose between TruArch for actual fish returns or selective Fish ID+ with target depth. This system also features a selectable large, easy-to-read digital readout with an adjustable backlight for night fishing, and Freeze Frame to instantly pause the sonar display, allowing more time to see the details. As an added convenience, this finder is compact in size, with an easy-on, easy-off mounting system that allows it to go almost anywhere. The 737 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.

The 737 runs on 10-20 volts of DC power, providing 500 watts RMS output and 4,000 watts of peak-to-peak output. This unit operates between 455kHz (90-degrees at -10db), 200kHz (20-degrees at -10db), and 50kHz (60-degrees at -10db) frequencies, and has a target separation of 2.5 inches to reveal close-hanging fish. Fully GPS-ready, this unit includes 750 waypoints, 20 routes, and 10 tracks with 2,000 points each. The 737 comes as a Transom Mount with a tilt-and-swivel quick-disconnect mount system, for either Gimbal or in-dash mounting, and measures 6.9 x 7.7 x 4.5 inches (WxHxD) as a gimbal mount, or 6.9 x 5.4 x 1.25 (WxHxD) when in-dash mounted with three inches of behind-dash clearance. For upgrades, this system is compatible with optional WideSide Bank Scanning Transducers, as well as Navionics Gold HotMaps cartography.
