I have a Garmin Echo 150 portable bundle that I use lots in the summer on my canoe and kayak. I am getting into ice fishing this year and am curious if I can use it for ice fishing. The portable bundle come with a float for the transducer; however I am not sure if the transducer will sit level in water. Not sure how well it will work overall too. If anyone has used there echo 150 for ice fishing and they have some tips or advice for it that would be great! I may try to sell the unit and get a Vexilar or a Lowrance ice machine.
