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 register a time. The timing chip will register a time within approximately 50 cm of the SI control station. Note that the SI control 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 register a time (50ms using Air+ mode, 60ms using regular mode). The SIAC is suitable for all athletes, but is particularly advantageous for competitive athletes and for sprint races.
Please note that this device contains a battery which SPORTident recommends be changed every 3 years. Your SIAC will quite possibly last longer depending on usage (we have seen 5 - 6 years), however to ensure reliability, consider a battery replacement every three years, especially before an important race. The unit is sealed and battery replacement can only be done by authorized agents. The O-Store does the battery exchange in-house with one to two day turn-around. We will also be present at Canadian Championships and will do SIAC battery replacement on-site.
