The 957c also has an external, 16-channel WAAS GPS receiver, and a built-in, 30-meter-per-pixel resolution UniMap of USA inland lakes, rivers, and coastal areas. This unit's high-speed, micro-dynamic transducer is reliable to 70 mph, and includes water temperature and GPS speed.
The 957c has a brilliant 8-inch TFT LCD screen with 480 x 800 lines of resolution in full color for enhanced separation, and an adjustable backlight. This unit features dual microprocessors and a graphics co-processor for fast, smooth operation, and the ability to upgrade with WeatherSense, PC accessories, and more. The 957c also features networking capability, dual memory card expansion slots for optional cartography such as Navionics Platinum charts with photo overlays and 3D viewing, and yet remains easy to operate.
The 957c includes chart recording to SD card, Bottom Lock to enhance resolution, a one-touch multi-level zoom, programmable view presets, and X-Press Menus so you can quickly access important controls. This fish finder also features both fresh and saltwater options, instant update to immediately show setting changes, full screen 3D chartplotter, and Freeze Frame to pause the display, as well as a man-overboard function to track back to that most important of spots.
The 957c comes with a transom mount transducer, and a tilt-and-swivel, quick-disconnect mount system, for Gimbal or in-dash mounting. This unit measures 11.25 x 6.75 x 4.25 inches (W x H x D) as a Gimbal mount, or when in-dash mounted requires three inches of clearance. For upgrades, this system is compatible with multiple other transducers with even more powerful performance.
