I have experience with the Down imaging from Lowrance with my HDS5, which is probably the closest thing the the new units from Lowrance. I Love the down scan, and have used it every time out. I don't use 2d at all any more, don't see the point when I can get picture quality views.

I'd say get it, and I'm at the point where I'm either going to get another LSS-1, or just get a DSI unit instead and use my HDS5 at the trolling motor for GPS, and the DSI for full screen scanning.
