I got my upgraded-to-version 5.6 Showdown back yesterday and immediately tried it out. I found that it worked substantially better than the prior 3.2 version unit that I had; however, it still didn't meet my expectations. One plus with the new software version is that one can move the zoomed area 1 foot at a time. This is a major improvement. It marked my jig well; whereas, with my prior unit it wouldn't mark my jig until it sit still for a couple of seconds. I didn't test it in water any deeper than about 45' but it easily marked my jig at that depth, and it likely will do so at far greater depths (my prior unit would not mark my jig any deeper than about 40-45'). The area that is still a challenge is interference. Anytime I was anywhere near George's Marcum interference was a problem. I tried stepping it through all 10 rejection levels and I could decrease the interference a little but that was it.
