The UNITED PBD, has been designed and tested, redesigned and retested, and is now absolutely the finished product we had set out to achieve. Power Band Design technology, unique to UNITED, enables our woods to redeliver the lost load (energy) at impact back to the face. In standard drivers at impact the head deforms and energy is lost, with PBD Technology the head snaps back into shape and the energy is regained giving longer shots. The aerodynamic design ensures the head glides effortlessly through the air with the least amount of resistance caused by turbulence. Again, as with the irons and wedges, the woods and hybrids in the range leave nothing to chance and the aesthetics are breathtaking.
