To aid in finding my bolts I like to paint the last 1" behind the fletching hunter orange. This is not too visible as the arrow is in flight but it can be picked up easily if stuck in the ground even covered with blood.

I have 2 bolts still missing from last season. Once all the snow is melted I will go back to look for them.
PS. I recoverd both bucks easily. The bolts passed through and went into heavy brush. As I was shooting from a ground blind they are real hard to find.[:@]
