I got a Humminbird 998C SI Combo and I can say it is wasted money for my part. Not because it does not work well it is because I just don`t really know how to use the think to its full capacity. Mostly use it for the GPS and depth finder. I usually just fish main lake and secondary points for SM fish and I just don`t see where it comes into play for that kind of fishing. I am planning on keeping it though because the wife got it for a Christmas present for me a few years back and besides it looks pretty good on the boat also.
