Bradenton Country Club Reopens

Bradenton Country Club has reopened after being closed for restoration Since April 15.  The iconic Ryder Cup captain Tony Jacklin CBE and Brian Lake, Director of Golf and PGA Professional led the upgrade project.  The renovation includes some raised fairways to prevent flooding, improved playability and ease of maintenance while returning the course to its brilliant Donald Ross design.

As part of the upgrade, Bradenton Country club is now offering its golfers a sophisticated way of returning their golf clubs to past glory as well.  An ultrasonic golf club cleaning machine provided by Rational Golf LLC of Bradenton restores the clubs.  Golf clubs are cleaned by millions of imploding gas bubbles removing dirt at a microscopic level, giving your clubs that new feel.

Bradenton Country Club has its own club fitting studio operated by Brian Lake.  Brian is trained in the revolutionary BioMatch method of matching golf clubs.  The BioMatch algorithm creates a model of the golfer swinging each of his or her clubs and thereby determines the optimum weight of each club.  The target weight is achieved by adding a specific proprietary weight inside the shaft at the grip end of each club.  The method provides significantly better accuracy to golfers at all levels.  BioMatch offers an effortless improvement to any golfer’s game.  The process applies to any set of clubs, old or new.  You can learn more about the technology at www.rational-golf.com.

If you want to be among the first to play the refurbished course, you may want to join the Manatee Chamber of Commerce annual golf tournament on Friday, December 7.  See more information online at manateechamber.com/golf.

Physics 2 - Swingweight 0

By Gisle Solhaug |

Bryson DeChambeau won the 2018 Dell Technologies Championship by two strokes over Justin Rose.  Thereby winning two times in a row.  DeChambeau is the only player in the field using a set of matched clubs.  He will also be the only player in the Ryder cup playing a set of clubs scientifically matched.  Anything we can learn from that?

The first thing one should conclude is that it makes sense to play with clubs that are matched so that you can apply the same consistent swing to all your clubs.  This can never be achieved with a set of clubs matched by Swingweight.  Every golfer needs to understand that Swingweight serves no purpose. It is now being used in a way that the inventor never intended.  Every player on the PGA Tour, except Bryson DeChambeau, is suffering from it.

There are disadvantages, as well as advantages, of having all the clubs the same length.  When all your clubs have the same mass, moment of inertia, and length you can apply the same consistent swing to all your clubs.  Being able to use the same swing for all your clubs is a huge advantage.  However, your "shorter" clubs will be less accurate, and your "longer" clubs will have a lower than optimal ball flight as compared to a standard set of club.  BioMatch gives you the best of both worlds.  You keep your standard length clubs while still being able to apply the same swing to all your clubs.  And I mean all your clubs, not just your irons, as is the case with the single length irons.

The current success of single length irons proves that there is a need for matching of golf clubs.  BioMatch fills this need without the golfer having to buy new clubs, and it does so for all the clubs in the bag.

BioMatch gives you deadly accuracy with every club in the bag.  BioMatch is easily applied to your existing clubs by installing the recommended size of weight to the grip end of your clubs.  The patented BioMatch application builds a model of your body swinging each of your clubs.  Thereby, determining the optimum weight to be added to each of your clubs for your body, hands, and clubhead to be synchronized at impact.  Your game will improve, effortlessly, once you have installed the weights.

Bryson DeChambeau's single length irons are all matched. The BioMatch method of matching golf clubs determines the optimum mass of each club in the set. The optimum mass is a function of club length, club moment of inertia, and lie angle as well as the properties of the golfer. As all these variables are identical for all of Bryson DeChambeau's irons, the BioMatch method will yield the same optimum weight for all his irons. As all his irons do have the same weight, they are matched according to the BioMatch method.

BioMatch at the 2018 WSCG

By Gisle Solhaug |

BioMatch was introduced to the Scientific Golf Community last week at the 2018 World Scientific Conference of Golf held at the University of the Fraser Valley in Abbotsford, Canada. The Inventor of #BioMatch, Gisle Solhaug, presented his work on Scientific Matching of Golf Clubs as a Poster Presentation at the #WSCG2018.  The WSCG brings together the leading minds in golf research to share their latest work as well as expose those findings to golf instructors and coaches in attendance.

Gaining acceptance for the BioMatch method of matching golf clubs from the scientific community is crucial for successfully spreading the solution to all golfers around the world.  The BioMatch method is confirmed to improve the golfer´s proficiency effortlessly.  After a golfer has had his clubs altered by inserting a specific weight into the grip end of each of his or her clubs, one consistent swing can be applied to all the clubs in the set.  BioMatch is shown to improve dispersion and consistency drastically.  Gisle is currently working with other scientists on a more extensive research program for further substantiation of BioMatch that will be peer-reviewed and published.

Hanging out with Sasho MacKenzie and the other golf scientist at the WSCG was a fantastic experience.  It serves as an inspiration to continue my work on helping golfers improve their game through proper matching of golf clubs.

Another BioMatch Champion

Joe Redoutey won the Club Championship and the President Cup at Harbor Hills Country Club, Florida. Joe, a 10 handicapper, shot a net score of 71, 68 and finished the third round with a strong 67. Congratulations!

Joe is the owner of Brodie Golf, the club fitting shop located at Harbor Hills Country Club. Brodie Golf, https://www.joereddgolf.com, became a BioMatch Fitting Center about a month ago. Since then they have been doing on average two BioMatch fittings a day. All with great results. As the only Biomatch fitting center in the region, Brodie Golf is attracting a lot of customers. I guess Joe is shooting himself in the foot as he will receive stiffer competition next year from the players that he has matched the clubs for.

Brodie Golf is also marketing their own complete range of golf clubs under the brand Joe Redd.

Science and Research in Golf

By Gisle Solhaug |

Science and research are about questioning old beliefs, right? Since the beginning of club making golfers have tried to find a way of matching golf clubs so that they can apply the same consistent swing to all their clubs. Building a matched set of clubs is considered the Holy Grail of golf. Today golfers still use the 95-year-old method of Swingweight. Swingweight was made as an approximation to MOI around the center of the grip (MOIG), as there were no instruments readily available for measuring MOI at the time. Today this arbitrary method is entirely off target as shafts are no longer made of wood and shafts of various materials are mixed in a set of clubs. It should be evident to anyone with a slight knowledge of Newtonian physics that the properties that affect how a club moves when swung are Mass and MOIG.

I have solved the problem of matching golf clubs. The solution is patented and is named BioMatch. I do not think I would have been able to solve the problem had I not been an outsider to the science of golf.  As a mechanical engineer, I was able to solve the problem by considering conservation of energy. The Swingweight method is so ingrained in golfers at all levels that very few can imagine a world without Swingweight. Even golf scientists and professional golfers match their clubs by Swingweight. When I tell these people that there is a better way, I am met with disbelief.

Last week I presented my solution to the 500-year-old problem under the Inventors Spotlight at the PGA Show.  Some club fitters are signing up to take advantage of the new technology.  However, one would imagine that the industry, in general, would pay some attention to such a breakthrough.

Anyone that has tried the BioMatch method will tell you that it does wonders for their dispersion and game in general. It works.

In an attempt to cut through the disbelief, I have written a paper on Scientific Matching of Golf Clubs. It is available on request. Independent testing has also proven the that the method works. However, a more scientific approach to testing is required to have my paper published. If anyone is interested in carrying out such a test, I have made a research proposal available on request. I would welcome any advice on how to move this forward.
