The Pro Speed Plus version of the original revolutionary Birtee Pro golf tees that are quick and easy to use for golfers of all calibres and ages. This new design has 6 larger legs as opposed to 12 smaller legs and is made from an advanced "higher flex" polymer that provides improved flexibility and durability. Also, the upper part of the legs formerly comes together in a reinforced solid section that attaches it to the ball support for greater durability. They also feature a higher, more flexible and durable plastic that has lowered the brittleness temperature for better results in extremely cold temperatures in winter golf. The set comes complete with 8 tees ranging in height from 1/4" to 2" with 1/4" increments. It offers every golfer a constant height for clubs of any size (Drivers, Woods, Hybrids & Irons) for every tee. They are also available in individual sizes. The BIRTEE PRO works on normal golf surfaces as well as any hard surface such as fitness/garage floors, indoor golf simulators and even frozen ground. It is designed to be reusable, durable, recyclable and more comfortable than traditional tees. It eliminates the need to push tees into the ground, but most importantly, it eliminates the guesswork out of achieving a constant tee height. The 8 constant heights give every golfer more confidence and consistency.
