Never miss another bit due to frozen line/tip-up! The thermal tip-up insulates the hole (up to 10") so you can stay focused on the task at hand. It also features two bite settings for different trip mechanism sensitivity so you can set depending on the species you're targeting. It even has a storage compartment for your favourite tip-up setup and folds up in seconds for easy travel and storage. Time to stop asking yourself, "I wonder if the line is frozen over" and upgrade to the Rapala® Thermal Tip-Up.
