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.
Additional colours coming! Starting mid-June 2023 we will also have turquoise and pink!
Replacement / spare strap for all SPORTident finger stick timing chips. The regular length straps is for normal use on a finger. The long strap is for use around a wrist - typically for ski-O and especially with a SIAC touchless timing chip for ski orienteering.
