I have an HDS Live 12 with the FFS for sale here at a substantial reduction vs new. I must say, the resolution in down imaging is amazing. On my Humminbirds, weeds show up as sticks but on the Lowrance, you can see the leaves and often tell what kind of plant it is. I was up on a northwoods lake and the crappie schools were easy to see and target.
The new depth finders are slower to boot up, I suspect because they are more like computers now than before. A lot of power to the processors than before.
