Here are the four main points of reference:
The Foul Line:
The line where the ball is released.
The dots are located half way between the arrows and the foul line. There are two sets of dots. One on the right side of the lane and one on the left. The dots are located on boards 3, 5, 8, 11, and 14. On the other side of the lane, the dots are located on boards 26, 29, 32, 35, and 37.
There are 7 arrows located fifteen feet past the foul line. They’re located on boards 5, 10, 15, 20, 25, 30, and 35. Use the arrows and the gaps between the arrows.
The Break Point:
The breakpoint is the point at which the ball changes direction and starts to hook towards the pocket. It is always effected by lane conditions. More and longer oil locates the break point further down the lane. As oil ‘stretches’ down the lane, so does the location of the break point! The actual break point is just past the oil/dry line.
First, begin using at least two points of reference on every shot. Pick a starting point and a finishing point using arrows and dots.
Play with determining which board is half way between your mark and your target and aim at that board’s dot.
Practice noticing the exact location of the breakpoint and see if you can determine when it moves down the lane. Focus on the line/spot that corresponds and helps you hit the break point.
