Just to be clear...not all lakes will EVER be surveyed at the HD level. The goal of the C-Map Precision HD is similar to that of Lakemaster - high def scans of the most popular tournament lakes in a given state....the remaining lakes will have basically the same level of accuracy as a Navionics card (generated from topo maps and other crowd sourced info).
There are over 500,000 lake acres in TN alone and when you consider the cost per acre to acquire that information using boats on the water and then figure how many cards you have to sell JUST TO BREAK EVEN, you can start to understand the economics of the situation. There is no way you can recoup the investment if you attempted to do all of that water.
The best way to get something more accurate is to use Genesis Social Maps....while not as accurate as an HD card, it is still usually much more accurate than the Navionics card.
Here is the link to Tims Ford on Genesis:

You can upload your own SONAR logs to keep improving the social map...and best of all, it is FREE...
That being said, never say never...and if the demand is great enough or you can get MLF to hold an event there...then it will probably get scanned!
