A Sandy bit is an award that you receive in the following situation.
- You are playing golf at Rowlands Castle Golf Club
- It’s the men’s Wednesday evening roll up
- Your ball has entered a greenside bunker "in regulation"
- You get down in two strokes
- Therefore you have a gross par… Which is known as a Sandy Par
So you win a BIT (25p).
Of course it’s also possible to play better than par and get a Sandy Birdie.
I’ve never done that.
