Here's a more in-depth look...
Built-in GPS Function - GPS track-plotting and chart-plotting made easier than ever before! With push-button simplicity, you'll be able to track GPS speed, mark 2,500 waypoints, chart 50 routes, and mark 20,000 points of interest.
DualBeam PLUS - 2 beams, best of both worlds! A narrow beam is optimized for bottom and structure detail below your boat, while a 60° beam casts a wider net, searching for fish and structure around your boat. View them side-by-side onscreen or combine the images into 1 comprehensive view!
SwitchFire - Gives you a real time, customized look below the water's surface with 2 different modes: "Max Mode" and "Clear Mode".
Max Mode detects even the slightest returns, displaying them on-screen in full detail, and helping you identify variables like thermaclimes, plankton and baitfish populations, structure and, of course, game fish. Max Mode is great for jigging, too, since its incredible detail allows you to see your jig on-screen. This complete picture of the action below your boat lets you tailor your approach to match the conditions and catch more fish.
Clear Mode offers a crisp, uncluttered representation of structure and fish... great for fishing in shallow water. Clear Mode filters out weaker returns like silt and debris, displaying only stronger signals like bottom contour, structure, schools of baitfish and individual game fish.
Pre-loaded ContourXD Maps - All-new ContourXD is an enhanced, professional mapping package. With over 3,000 U.S. lake maps in the database, you will be able to find a lake close to any location you might want to wet a line. As an added bonus, ContourXD maps will feature depth contour lines, so you can find all the drops, bumps and channels holding fish. The maps will also include U.S. lights / markers, and major roads and interstates. Fish like a pro on your home lake, or a lake far from home.More Advanced Sonar features:
