Maximize every moment of fishing when you upgrade to the unrivaled accuracy and detail of Humminbird LakeMaster mapping, which features easy-to-read contours, highlighted depth ranges, and scrollable lake lists. 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 Great Lakes Edition, Version 4 boasts more than 380 lake maps in high definition and over 1,540 total lakes from MI, IN, and OH, with over 140 lakes added since the prior version. Version 4 includes updated shallow-water areas for Lake Michigan and parts of Lake Superior, full coverage of Lake Superior, all of Lake Huron (including Georgian Bay), Beaver Island on Michigan in HD, a new HD survey of Lake St Clair (including Canadian side), and more. Easy-to-see shading highlights shallow-water areas within an adjustable range up to 30 feet, and depth contours and shorelines can be synchronized with the actual water levels of lakes, reservoirs, and rivers. LakeMaster digital maps 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. LakeMaster 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.
