Re: Driving Distance
Imagine knowing with virtually 100% certainty, the distance to clear the bunker, to the front edge of the green, to the pin and to the back of the green - real data in the real world - a launch monitor can help you choose the right sticks, but if you really want to get the most out of them, you really need to know your yardages.
Most yardage markers are bang on accurate - but the thing is you don't always know what they used as a reference - I've seen courses that always use 1/2 way from front to back (most common) and other courses that use the centre of the widest part of the green.
You really need to know how far you drive the ball though. If it's shorter than you think, a smooth swing might leave you in a hazards. If it's farther than you think, a smooth swing could be through the fairway and into the creek.
