if youre running humminbird then lakemaster, others then Cmaps
lakemaster has the function of being able to offset contours with current lake level and then highlighting various depth ranges. for instance, on my console nav unit i keep 5' or less highlighted in red, then as i adjust for the current lake levels i see where i can and cant run. ive only been here a couple of years but have been able to navigate the lake regardless of lake level without issues. the other REALLY nice thing is the depth highlight, if you figure out a depth that the fish are in you can highlight the depth and the eliminate a lot of water.
Churly, ive been told Cmaps has the depth highlighting capabilities, true? what about offsetting for lake levels?
