Shot Scope devices can be used in almost all amateur competitions. If you are playing in a competition that doesn’t allow the use of distance measuring devices then you can use the watch in Track mode. Track mode is legal in all competitions, including professional tournaments, as these modes do not provide GPS distances when playing but they still record shots.
The Shot Scope lasers can be used in most amateur competitions but there may be some elite competitions that don't so please ask a rules official for confirmation before the start of play.
The slope adaptation feature can't be used in competitions.
