SIAC Active Card includes an elastic Finger Loop. It holds 128 Punches, battery life is approximately 4 years and can be replaced. When timing data is written to the SIAC at a control, the translucent tip produces several vivid flashes and the SIAC makes several shrill beeps to confirm success.
The SIAC is used for almost all MTB Enduro events worldwide. It is perfect for ALL orienteering events and when used contactlessly, you only needs to pass within 0.5M of a control. The SIAC can also be used at events with Direct Punching where you dip it in the station, just like any other SI-Card.
