The pCard timing chip is ideal for groups and events where the number of controls is always small. pCards are suitable for school orienteering and for Enduro races. pCards come with a wrist safety strap. They hold a maximum of 20 controls, including any errors or duplicate punches so we recommend only using for events with 15 or fewer controls.
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.
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.
