Copper does a great job not freezing to the ice. Designed to fit several ice rod and reel combinations. I recommend 29 to 36 inches rod length. Adjustable trigger for different fish species bite sensitivity, bait size "small minnow/large minnow". Adjustable Torque tube and torque tube extender designed for different rod lengths and strengths. All adjustments are simple and quick. Once adjusted to your pole and sensitivity choices, can stay there without further adjustment.
