CatFan is dead on !!

I think Lowrance having the best DI was from some years ago, when they had units with dedicated crystals for DI and didn't get the DI image from the SI input. Humminbird brought out the ONIX series just to compete with Lowrance's dedicated DI crystal (IMHO).

My unit is DI only (Elite 5 DSI) and is no longer made. It was superseded by the same head unit, but with 2d imaging added in (Elite HDI series).

This is the best screenshot showing fish that I've taken to date :

Most other screenshots, and even the images on the screen when I'm fishing, will show single fish as simply white dots (much like the larger white dots above the "fish shaped" images in the screenshot above).

Can't say for sure, but I'd think that a larger screen would enhance the potential for getting better fish images. My unit only has a 5" screen, plus it's several years old ... so there's been ample time for competition between the major brands to upgrade the technology.
