Does anyone know anything about that software. This is what I understand it to be.
Lake Insight™ inland mapping includes nearly 5,000 freshwater lake maps with lifelike perspective of bottom structure and topography. Coverage includes the Great Lakes and more than 500 Fishing HotSpots PRO® Lakes – a $400 value! Insight high-definition mapping delivers unprecedented detail with lightning-fast map and screen updates.
Question is, is that mapping really accurate? As in surveyed? If so, what company is doing it for them? If this lake stuff isn't surveyed in what is it worth? Sakakawea even included in it?
