I hear and understand and I do agree, but I don't really think I need "intricate navigation" for my purpose on these waters. My boat and knowledge work well for canals and small lakes, I just need to know where they are. Even just running from the canal by my home to the Tsala Apopka lakes can be very confusing with the tangle of canals. The Garmin Topo 2008 that I posted screen shots of in post #2 would work very well for me.
As I said, my CD is in storage and it's not practical to go and get my stuff at this time - 2,000 miles each way. It's a very long and unhappy story, but I did talk to a friend back there a week or so ago and he's agreed to go into my storage facility to find and ship a few things to me - one of which will be that CD.
When I was really digging into it, I was told by several "apparently" knowledgeable people that the Garmin files can be converted to Lowrance files. Wonderful, and I've already downloaded the program to do that.....but if it turns out not to work, I do have that program in my hand held now. Not quite as convenient to navigate with, but it does work.
I appreciate the thoughts. Thank you.
