The Wilson Staff Dh6 utiity club is a hybrid that incorporates the company’s breakthrough ETF (Energy Transfer Frame) technology and optimal internal weighting to add distance and higher launch, easing the difficulties of the long iron shot. ETF technology structurally reinforces the area just behind and around the Wilson Staff Dh6 clubhead face to optimize energy transfer back to the ball at impact. Because the crown, sole and skirt of most traditional utility clubs are very thin, energy is often lost on impact because they lack the structural strength to maximize the energy transfer most advantageously to the golfer. Through ETF, Wilson has developed a proprietary laser welding process adding a discrete and virtually weightless weld line that frames the face and captures energies previously lost in the clubhead. This added energy directed back through the face of ETF, produces extra distance and results in an expanded, high COR or ‘hot zone’ area double the size of any club without ETF. This ‘hot zone’ produces longer and straighter off-centre hits and ETF technology will be featured throughout the 2006 line of Wilson Staff drivers and fairway woods. The club features a 100% stainless steel clubhead with a low profile and thinner face for increased forgiveness and playability. Extra internal weight has been placed in the back sole, for a lower centre of gravity that helps to get the ball airborne and produces maximum distance. A wide, rounded sole makes it easy to hit, even from the most difficult of lies.
