All SPORTident finger stick timing chips come with a finger strap.
The SIAC (SPORTident Air+ contactless timing system) timing chip is the only SPORTident timing chip that does not require contact with the the timing control to regsiter a time. The timing chip will regsiter a time within approximately 1 metre of the SI control station. Note that the SI conrol station must be set to Air+ mode for this to work; if not the SIAC will act as a regular timing chip requiring insertion in the control station.
The SIAC timing chip holds times from up to 128 controls. It is the fastest of all the SI chips to regsiter a time (50ms using Air+ mode, 60ms using regular mode). The SIAC is suitable for all athletses, but is particularly advantageous for competitive athletes and for sprint races.
