Obviously there some units that are a better choice for ice but YES, You can use of of the less expensive units and they will do a good job. As Joni mentioned the cold can play havoc with the LCD screens. If you are in a shed that is warmed you wont have too many issues. If you are out in the open use a couple of the disposable hand warmers taped to the back of the display screen I used a small platic box with a little insulation behind the screen and a couple hand warmers. I got by for 20 years that way on a very inexpensive lowrance and I only had to use the hand warmers in sub-zero weather.
