Frabill's Pro-Thermal insulating tip-up offers easier and more productive tip-up fishing. Round shape and thick insulation covers the entire hole to prevent freeze-up, even at -25°F! Seals the hole to keep blowing snow and slush out and blocks unnatural sunlight that can spook shallow water trophies. Easy stow design allows you to stack tip-ups in a 5 or 6 gallon bucket. Flag lock keeps flag in an upright position and visible regardless of wind conditions. Spinner marker, reel handle, and trip bar offer two trip settings-light or heavy. Revolves to show fish movement, serves as a reel handle to retrieve line. Large bait clip prevents oversized baits from creating false trips. Line releases off the clip on a strike. Removable spool shaft, pre-lubed with Sub-Zero lubricant. Includes 50 Yards of 30# braided dacron line, line marker, depth finder, built-in tackle box, patented hook holder, line guide stop, and Lil' Shiner Tip-Up Light.
