Just got my new Lakemaster Great Lakes ver. 1.0 map chip in today. Wow! This is impressive! I love the features. You can highlight depth ranges into three sections that you decide the depths, offset lake levels, adjust the colors and change lakes from a list in the menu. Most impressive of all is the map detail. Their hd lakes are unbelievable. This makes my Navionics chip look like an etch-a-sketch.

One thing I'm a little disappointed in is a couple of my favorite haunts are not mapped yet.

I live mine as well. Clearly a well done product. Share the view that there are some spots not yet mapped. But still find it very useful.
