Hey Steve,
I didn't really consider the UHD 94SV as I'm not a fan of an MFD that uses any buttons other than the power button and prefer a touchscreen only device. I know I'm probably one of the few in that regard but I've used MFD's in the past that had the buttons only, or touchscreen as well as button usage and never liked using them. I figured for the extra couple hundred bucks that I'd splurge a little and get what I really wanted as well as it fit within my budget since I was trying to keep it less than $2k and hopefully closer to the $1,600 range, which I did do. The second unit in the picture is a Garmin Striker that actually came with the boat when I bought it as well as the 7" touchscreen unit that went belly up. I just kept it on there for redundancy and a backup if it was ever needed, or if I had an issue after installing the new 943xsv as the Striker was already installed and working fine when I bought the boat. I really like the 943xsv, about my only "gripe" with the setup is the flip up storage area that I have it mounted in as it makes it a bit of a chore to operate, although that's obviously no fault of the Garmin itself. I think over the winter I'll seriously consider flush mounting it or possibly some other option like mounting it above in the overhead area where I've got a radio and stereo currently, but the Garmin unit itself has performed flawlessly. I like the size of it and am glad I didn't go any bigger like with a 12" unit as that to me would've felt like overkill and a waste of money again imo for only a 22' boat.
I've got an iPad with a suction cup mount so if I'm fishing with someone else that is driving and I want to see my depth or where the fish are back by the stern of the boat, I can sync up the iPad and mount it on the cutting board or elsewhere and it mirrors the Garmin up at the helm. Kind of cool, not everyone will likely use that feature but I enjoy having that option as well as the SideVu which I probably won't use a lot for my style of fishing, which is trolling for salmon, but do like having it as an option if I did want to use it for some reason. I'm of the opinion that it seems like MFD's and other GPS units are great but they don't pick up everything as I've caught fish that weren't even showing up on the unit before, and mostly use it for speed, depth, contours of the bottom of the ocean and marking where I've caught fish in the past. The MFD telling me that I've got fish below me sounds great in theory, but again I don't really know if those are salmon, seals, dogfish, porpoises or so on. They give you different colors for sizes of the fish but I don't rely on that alone and typically fish the same area all the time. I'd definitely buy the same setup that I bought again as I've had no issues with it, the unit is very easy to use and operate. I'll see what kind of pictures I currently have of it and post them.
