If a player believes his ball may be lost outside a water hazard or is out of bounds, to save time, he should play a provisional ball.
Players searching for a ball should signal the players in the group behind them to play through as soon as it becomes apparent that the ball will not easily be found. They should not search for five minutes before doing so. Having allowed the group behind to play through, they should not continue play until that group has passed and is out of range.
