- Tracking mode only, no use of OK or Custom messages at checkpoints.
- Using OK too far away from the checkpoints.
- Not turning on their tracking device while on the water.
- Improper setup when using Garmin so that OK, Custom, and Help messages cannot be identified.
One more thing, if you have two tracking devices, just use one of them during the event. Save the second in a safe and secure location as a backup. Two is one and one is none. But for practice, switch them up so that both get tested in our tracking map.
