I picked this up from Paul Beaupre a few years ago on the tolt, Take a 1/2" x 1" sponge and use rubber bands to attach it tightly behind your second eye back fom the tip' then fill up a small empty scent bottle with anti-freeze. Then every 10-15 min add a drop or two. I haven't had ice in my guides since! Give it a try,you will be in the water fishing 2 to 1 over your buddy!
