For your water fishing adventures, Humminbird fish finders will ensure you are well positioned. You can expect more hook-ups on your next outing when you have the Helix 7 SI GPS Fishfinder fromåÊHumminbird installed on your boat. This combination fishfinder and GPS unit provides you with many views of the terrain under your boat. Side imaging gives you a 3D picture 100' to the side of your vessel, while down imaging gives you a fish-eye view of the world directly below your boat. SwitchFire technology allows you to choose between clear or max mode to filter out noise or show more detail using an advanced algorithm that filters out interference. DualBeam Plus lets you choose a wide coverage area, or a narrower sonar cone for more detail. This system has an RMS power output of 500W, and a peak to peak output of 4000W, providing an accurate representation of the bottom down to 100' (SI) & 1500' (2D), which is displayed on the 7" diagonal color screen. The transom-mounted transducer features multiple coverage angles of 20, 60 & (2) 85å¡ @ -10db (Total of 180å¡), so that you can adjust the coverage to suit depth and angling conditions for the best returns.

With an internal GPS antenna, you will always know where you are and how fast you are going. Mark waypoints for structures or areas where you've had angling success and return to them at a later date. Built-in UniMap cartography covers the contiguous US coastline, inland lakes and rivers at 30 meters per pixel resolution. Load optional cartography using the micro SD card slot for access to higher resolution maps of waterways across North America.
