ErnDog- I went from a Humminbird Wide100 to a Humminbird 3D Paramount. I love that I can really see what the bottom is doing in a 3 dimensional view. When we were off Dalco point, we could see the wall coming and avoid it. If in 2D view, we wouldn't have seen it until it ripped the balls of the downriggers. My partner has a Lowrance unit that we are thinking of mounting on the back of the boat so that the guys working the riggers can see whats going on. The Paramount sucks at a 2D view in that you can turn off the "fish" symbols and get just the raw sonar "arcs", but the screen speed is too slow even on its fastest setting to distinguish anything. This is my only complaint. The large screen is great, the greyscale levels are awsome. The Wide100 SUCKED! I would probably go with the Garmin if I had it to do over again. Let us know what you get and how you like it.
