Combining high-definition LakeMaster lake map data with extensive search algorithms, Humminbird SmartStrike takes you straight to the action by showing you where the fish should be biting at any given moment. Based on search parameters like season, time of day, temperature, and targeted fish species, SmartStrike highlights areas of the lake map where your fish are most likely to be located before you even wet a line. LakeMaster digital maps provide the most detailed, high-definition collection of freshwater mapping in the United States, with unmatched depth contours between 1-3 feet (in high definition) or 3-5 feet (standard definition). This SmartStrike Northeast States Edition, Version 2 boasts more than 130 high-definition lakes and over 1,700 total lakes from PA, NJ, NY, CT, MA, VT, NH, and ME. (SmartStrike available only for high-definition lakes.) Newly-surveyed waters include Annabessacook, Big Pond, Chickawaukie, and Crescent in ME; Cayuga, Oneida, Seneca, and Six Mile in NY; and Chambers, Raystown, St. Lawrence Moses East, Champlain, and Ossipee in PA, VT, and NH. SmartStrike includes such LakeMaster features as selecting a particular depth range, adjustable highlighting of shallow-water areas up to 30 feet, and synchronizing depth contours and shorelines with the actual water level of lakes, reservoirs, and rivers. SmartStrike can be used with Minn Kota i-Pilot Link (sold separately), allowing you to follow a selected depth contour line to deliver precise, automatic boat control. Collected by Humminbird's own team of GIS analyst cartographers, LakeMaster high-definition maps are created from on-the-water surveys using hundreds of thousands of depth soundings, plus state-of-the-art GPS and sonar technologies. SmartStrike digital maps come on a Micro SD card (with included SD card adapter) that's compatible with all GPS-equipped HELIX, SOLIX, ONIX, and ION Series models and select 600-1100 Series models. Strictly intended for use in your Humminbird GPS unit, SmartStrike mapping cards are not PC compatible and map files could be corrupted if accessed on a computer. See moreShallow water highlight.
