Pros have been using a number of different pendants, magnets and bracelets in a bid to gain a competitive edge over their rivals. Proof of their effectiveness has been hard to assess, but the makers of the QLink are confident that their product has measureable effects on a golfer's wellbeing that leads to a direct improvement in performance.
The QLink pendants contain 75ft of wound copper wire and are designed to pick up bioelectric impulses from the body. The makers claim they can increase mental focus and physical stamina.
The science behind QLink is called Sympathetic Resonance Technology (SRT), which is designed to improve the performance of the body and build up resilience to stress. In layman's terms it works a bit like a tuning fork acting on the trilions of cells found in the body.
Over 200 US PGA, European, LPGA, LET and Senior PGA Tour members wear a QLink, winning almost 40 tournaments worldwide between them. At least 14 players have won within 5-10 days of putting it on, including Mark Calcavecchia, Scott McCarron and Sweden's Jesper Parnevik.
European Tour player Steve Webster has been using one for over a year. "A Friend brought one back from the States and I first wore it at the B&H. Within a month, I had finished 11th at the PGA championship, 5th in the English Open and 4th at the Great North Open. I was playing okay before, but it has really helped my mental side and made a huge difference to my concentration."
To date over 1,000 golfers have taken part in stress testing with the FDA-registered BEST system and 99.9% showed an improvement with the QLink.
Away from the course a range of further benefits has been reported. These include more energy, better sleep, fewer headaches, greater focus, a decrease in anxiety levels and reduced jet-lag. Other wearers have said it helps with some skin conditions (such as eczema and minor cases of psoriasis) and even hangovers.
