Thanx! That clears up alot!!! In your opinion, if you were me, would you buy the auto chart software, since most of the lakes I fish are not on lake master cards? I fish 2-4 days a week depending on my work days and have the time to make my own maps if needed. And I can also use autochart on river systems as well correct? PM me the answer to the first question if it will get you ridiculed from some sort of advertisement. Not trying to get anyone in trouble or fired up, just wanna get the most out of my money.
