Haven`t seen the printed virson but I have Navionics Hotmap Explorer on my computer. If the printed maps are as good as the one you buy for your computer they are great. I have only downloaded one map so far. Pickwick lake and have found stuff that I didn`t know was there. It is fun to find the new locations with GPS cordinates. Then print out your map and find them the next time you are on the lake.
