Learn to always hit on the sweet spot, and force your concentration to a higher level with the new Sweet Spot Trainer (SST) 80G from Black Knight.
The sweet spot of the SST 80G is the same distance from your hand as the sweet spot of a standard 64.5 cm racquet, so that you will use your natural swing and timing. However, the SST 80G’s head is much smaller, and the result is immediate bio-feedback if you miss the sweet spot. Heighten your concentration as you master hitting on the sweet spot every time. Go back to your usual racquet and be amazed at the improvement.
