So I sold my FL-8 yesterday on Craigslist in about three hours, which kind of surprised me seeing that we're nearing the end of ice season. Anyway, I've started fishing a lake where the fish are very bottom-oriented and would like to upgrade to a unit with zoom. I like the flat faced units as we typically fish two people off of one flasher and they are much easier to view from a variety of angles. I regularly see the Humminbird Ice 35 compared to the FL-18, why isn't it compared to the FL-20 or FL-22? How does it compare?
I'm a Vex guy and really want to march out and buy a FL-22 because I never fish water deeper than 60', but am having second thoughts due to the price point of the Ice 35 and lack of potential interference issues between it and my other FL-12. There appear to be a lot of nice features on the Ice 35 for the money, just not sure if it is an apples/apples comparison to the FL-22.
For that matter, what additional features do the Ice 45 and 55 add other than the digital depth display (which I could care less about)?
