I personally don't have one but shoot with several who do. They generally take a reading before they before they approach the line and gage that against other indicators. ie, flags, vegetation,mirage, etc. It then goes back into it's pouch until the next relay. But these ranges are not open to alot of wind. It's the direction changes that are the killers.
