Just about anything you buy now will be a real improvement over what you have. I switched to a Humminbird 1197 a few years ago and have been very happy with it. I still have a Lowrance 520 on the bow that I rarely use that works fine. I will say that it seems that Lowrance is having some issues now with the new HDS units some could be internet hype, but I went in to check out a Lakemaster chip out and at a store and the HDS 10 unit it was inserted into crashed several times while trying to zoom in to look at Lake Superior. It never did stay working long enough in the store to see what I wanted to see. The guy working even muttered these new units suck. Good thing I wasn’t there to buy a Lowrance. Maybe all they need to work properly is a software upgrade I have no idea, but I know I wasn’t impressed with that one anyway.
