The SIAC (SI Air+ touchless timing chip) is the newest and fastest timing chip available. See below for details of the touchless system. Upgrade to a 25 cm timing chip strap to allow it to be worn around the wrist for ski orienteering. Add a wrist safety strap as extra protection to prevent accidental loss during an event.
Please note that due to the need for a unique name associated with each timing chip, you will only be able to choose a quantity of 1 for this product. If you would like to order multiple timing chips, please add the first to your cart, and then enter the name for the next chip before adding another to your cart.
