Thanks to good info from Skeeterbite, I got me the above mentioned unit, believe it’s an Elite 5x DSI. All it has is DSI, no GPS or anything else. I use it in conjunction with my 510c and it’s working nicely.
The first screen shot was the best I’d seen so far. It’s on a private pit where the owner sunk a hog trough or panels, one of the two, do not remember exactly what he said. But you can see the rails very clearly with fish hanging out around it. Very cool.
The 2nd shot shows a bunch of brush or stick-ups on the bottom in one area. We also had a shot of a tree where we could count the branches, sure wish I woulda got a shot of that. After the 2nd trip out with it, I’m impressed and think my $350 was well spent.
