Abstract: Firstly and foremost, the invention is novel and non-obvious because no entity or person known to the inventor as of the filing date is marketing any system, product or series of products that links or integrates a set up instrument to custom fitted golf clubs. The inventor believes that to a very significant degree, the golfers set up predetermines the motion. A golfer may set up to the ball perfectly and swing perfectly but if the golf clubs don't fit the golfer, the flight of the ball will definitely be compromised in a variety of ways. Or, a golfer may obtain custom fitted golf clubs but if he or she doesn't have a way to duplicate and reproduce the set up, which predisposes the swing, the golfer's swing will probably change, primarily, because the set up changed. The invention herein is much needed for golf game improvement because it systematically controls the most critical variables in golf. The inventor believes the SET UP and CUSTOM FITTED CLUBS go hand in hand.
