The following is a report is on a comparison between the Divnick adjustable golf club with loft-degrees set to correspond to steel-shafted 3,4,5,7, and 9, modern no-hosel irons. These clubs are high performance and modern and are comparable to the top blades on the market. The speed was adjusted based on the Divnick iron at 90 mph. All clubs were hit at this load (the energy output was constant). All clubs were hit in the center of the club face.
The numbers measured were the carry of the golf ball and it's distance from centerline (dispersion). Head speed was also noted.
The trajectories on both the Divnick and the irons were nearly identical. The Divnick had a swingweight of D-0 and the iron was D-1.
The testing matrix went as follows: each club was hit 12 times, with the Divnick being hit first, then the corresponding iron, followed by the Divnick,etc. The summary numbers below were calculated by adding the individual averages of the 12 shots per loft and dividing by the total number of clubs.
