Downstroke and plane

[golfquest]

Sorry hardly ever post, but have another question that I need a little defogging on. I seen several posts about the plane line, flashlights etc. I have a device that will flash on the plane line. However, I use the right hand pick up etc and the light traces the base of the plane line. But, when in the downstroke for a hitter they indicate coming on a straight plane line down out and forward. Would this mean that the laser or flashlight does not trace the base line of the plane but instead make a light beam coming from inside to the ball? Again thanks for your time and consideration in helping to lift the fog. Stan
