Captains of Crush Key: MILES to MILS
GPS For Your Grip Strength Training
Know where you are and you'll reach your goal faster. The CoC Key from IronMind is designed specifically for use with a set of Captains of Crush Grippers (sold separately), and helps athletes to “gauge the gap” and track their progress by precise increments as they move toward a new grip strength goal. The Key is made from aircraft-grade aluminum just like the CoC Grippers themselves, and can gauge steps of 2mm, 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, and 16mm, along with 19mm and 54mm measures.
