1. You have 3 minutes to search for a ball so time the search from when you get to where you think your ball may be. It can be difficult to find a ball in the soft ground after all the rain we have had.
2. If a crow takes your ball replace it or another ball on the original spot, which if not known can be estimated. No penalty. It must be known or virtually certain that the bird took the ball otherwise the ball is lost.
3. When you place the ball during the preferred lie period you can play either the original ball or a substituted ball under the new rules.
