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 LakeMaster Plus Great Lakes Edition, Version 2 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 2 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. LakeMaster Plus enables you to view an aerial image overlay on high-definition waters to see the entry and exits of creek channels, to see how far a reef or weed line extends, and to pick out shallow-water rock piles, steep drop-offs, and other features. 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 Plus 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, LakeMaster mapping cards are not PC compatible and map files could be corrupted if accessed on a computer.

I spend lots of time on Lake Superior in various boats. This chart set is the best, most accurate I've seen for the area. Very rarely do I notice a skew in location. Depth contours are generally pretty good, and the symbols/cartography and level of detail are good.Very good investment if spending significant time on the water and need good accurancy/detail on the charts.

The Hummingbird unit comes with built-in maps but in order to unlock the "follow the contour" feature you need to buy a Lake master card. These cards are supposed to have more detailed maps than the ones that come with the unit. However, they may not be accurate enough to actually follow the contour. This card did unlock the follow the contour feature but on the lake I fish most was plus or minus 15 feet in either direction of the contour. So trying to follow the 25 foot contour I was in 10 to 35 feet of water. I don't need electronic boat control for that kind of accuracy. I can do that blind folded by myself. I have contacted Hummingbird about this and other issues. I'm still waiting for a final resolution.

Original chip didn't work on any of my Helic units. Submitted a claim and received a new one about a week later. Second chip works as it's supposed to.

I like that this works reliably and is in a familiar format. I have several Lake Master chips, and prefer them over the several Navionics chips I own. Mostly for the compatibility with my Minn-Kota's follow-the-contour feature, but also for the familiar interface I've grown to know & trust from other Lake Master products.One day I'd like these to be $10 instead of $125+.

Purchased primarily for Lake St Clair ice fishing. LOTS of lakes included. Purchased for my ICE Helix 7 G2 and is more than I even expected.
