Anyone have any experience with this product?

It has all the coastal U.S. waters, plus all the freshwater lakes and ponds that are on the Premium chips from Navionics.

Can't plug it into your fish finder, but you can put routes into a chip which you then plug into the port on the sounder, and it will overlay (if that's the correct term) the course onto your gps display.

For 130 dollars, it looks like a bargain to me.

That's neat, and ideal for waters that aren't available in hi def on the navionics chips. 

But, when planning to fish water you've never been on, that program won't do much for you, unless you want to take the time to chart the entire lake. 

Even then, it won't identify old river beds, bridges, submerged or standing timber like the hi def maps do.

It wouldn't have helped me when we went to Pickwick last year, nor studying Lake Kentucky before getting on the lake in April.

I'm 69, and the time remaining is too precious for me to chart waters when there are maps available, with more info than I'll ever use.

It does look interesting though, and something for me to consider.
