The navlight scoring system will be used. Each team will be issued with two tags which must be fitted using the supplied wrist-band to two team members. For a mixed team one member of each sex must wear a tag. Each of these team members must record their visit at each punch. The last to register is the allocated time.
The NavLight system has two main components; the Punches and the Tags. The Punches are powered by one AA battery and hang from a cord at each checkpoint. The Tags are un-powered and are worn on the wrist by the competitors. They are attached with a security band.
When you visit a checkpoint you record your visit by inserting the Punch into the Tag; a process which typically takes half a second. A red light flashes regularly to indicate that your visit has been recorded.
Apart from the Checkpoint Punches, there are some special-purpose punches which you MUST be aware of. They look the same as normal Punches but have been allocated a special Status.
- Use a BRIEF Punch before the event start.
- Use a FINISH Punch whenever you return to the Administration area.
- Use a DEPART Punch if you have returned and go out again.
After you have used the FINISH Punch at the end of the event an organizer will remove your tag from your wrist (do not remove it yourself) and it will be scored. Wait for your printout which will look something like this: (Start time was 6:40:00 PM.)

Note that on line 13, the recorded time was a year early. This happens if the battery has been momentarily disconnected in the Punch sometime before you got to it. Although the time is wrong, you still get the points.
The function of special-purpose Punches is described in more detail below.
- TEST Punch. This is available at Registration for you to try your Tag to see how the system works. It has no effect on your score. If the red light flashes even once, it has worked.
- BRIEF Punch. One or more BRIEF Punches will be available shortly before the event start. You will usually find the BRIEF Punch as you enter the Briefing area; hence the name. Officials may inspect your Tag to ensure it is properly fastened on your wrist so it is important that each Tag is registered on one of these Punches BEFORE you start the event.
- FINISH Punch. Several of these will be available at the finish line. ALL team members with Tags MUST use one as you finish, as it records your finish time. For a team, the finish time is taken as the time of the last Tag to finish. If you return during the event, you should still use a Finish Punch. It doesn’t matter if you subsequently go out for more checkpoints, as long as you use a FINISH Punch again when you return. Earlier Finish times will be ignored.
- DEPART Punch. If you visit the administration area during an event, and use a FINISH Punch when you arrive, you must use a DEPART Punch when you leave again.
