Club head Design

From a visual science point of view, Stellander's aim was to construct a club head that had the information needed to give an impression of squareness, where the player is aiming and whether the club head is moving along the optimal and a consistent stroke path. And last but not least, whether the eyes are parallel and perpendicular above the centre of the club head and ball.

Too many putters on the market today, are merely constructed as designs trying to please the customers and trends, but actually decrease performance. They have visual noise, design features making the brain aware of these features, which then distracts the critical process the brain goes through estimating the force needed in the stroke.

The aim was to design putters with a smooth shape that minimizes visual noise, making the brain focus on the ball and the hole while still giving visual information about the club head and the all important indicators. The distance evaluation process should not be distracted by either focussing on the alignment features or by design features and colours that make the brain aware of and interested in those features not solving any aiming or aligning problems.

Profound Putters have ultimate contrast from head to alignment indicators with non-reflective surface of the club head to avoid glare. These features are present on the Profound Putters and are needed to achieve optimal visual feedback from the system.

The high contrast tracks that frame the ball are visible in the peripheral vision. This is crucial to maintain focus on the ball and the hole for estimating the force needed in the stroke. Light focus on the back of the ball will increase peripheral vision detection area. This also decreases visual fatigue by reducing the movements of the eyes during a round of golf. Visual fatigue leads to lack of concentration and confusion.

Squareness is very easily detected with the Profound Putter designs due to the two rear parallel design features of the ACE series putters and the basic T-shape of the club head. They enhance both squareness and stroke path indication.
