I purchased a Humminbird ice 55 flasher last season. Love it! Never used electronics on the ice til then. U can zoom in on different depths of the water column, watch my bait as it descends, has dual beam transducer to narrow down the viewing area or expand it to a wider profile. Used it while jiggging walleye in 43 fow, saw fish at 20', reeled up, fish on! Also amazing to watch a whitefish dart off the bottom to hit my suspended bait! Without my flasher I would not have known there were fish cruising at different depths. Won't go ice fishing without it!! To add to what others are saying about the expenses involved to get out fishing, if I account the boats, motors, ATV, rods, reels, tackle, clothing, ice shack, heater, gas, motel, meals. My fish is approximately $852.00 per pound!! HAHA!
