DICKHEAD™ Keeps Your Eyes on the Ball

Field notes

The system organizes its hardware around two variables that most tennis product pages would not foreground: stroke direction and dominant eye. Dedicated models use single-direction tension, while the Pro configuration is described as having reversible anchors for four selectable setups. The page says the product requires no sensors or subscription, but the extracted material does not confirm fulfillment, stock, or independent testing. A request-access link and sign-up call suggest that at least part of the purchasing or onboarding process may remain gated.
