Need a new flasher
I also have an Ice 35 that I used all last year and absolutely love it. Cheapest 'flasher' only I could find, and the screen is much larger than most. Also very simple to use and the zoom works wonderfully.
Right now, I actually use a combo of the Ice 35 and a Humminbird 385c. I use the 385c for the map, with the LakeMaster chip since the contours and accuracy make finding spots very easy. It just isn't that great of a flasher and I fish a lot with a friend with a Marcum and the interference is so bad it's almost unusable (I've seen people be able to tune them to fix this, I haven't had any luck), so I just the Ice 35 once set-up.
