The set consists of two 4″ plastic cylinders, connected by a cord that easily fits into a pocket. Each cylinder contains a sturdy steel pick that is protected by a retractable, spring loaded guard. When plunged into the ice, the guard retracts, allowing the pick to penetrate the ice. The person who breaks through the ice uses one in each hand and with a hand over hand stabbing action, alternately plunging the picks into the ice, thereby pulling oneself in a prone position across until one reaches firm ice. The set is bright orange for easy visibility. Made in USA.
