The 3Dinsight™ tracks are geometrically constructed by using the simple concept that a circular plane, or a disc, can be seen as a perfect straight line when two criteria's apply. Parallel and perpendicular eyes to the edge of the circular plane.

Depending on misalignment one of the tracks will increasingly disappear behind its sidewall, while the other will appear increasingly elliptical. In other words, the image changes depending on eyes position in relation to the club head.

An additional feature is a bright orange warning colour added outside the tracks, in the bottom of the "windows" on the sidewalls. The colour will increasingly appear depending on degree of misalignment. When only two parallel lines are visible, then you are at perfect set up position with eyes over the ball.

Other high contrast systems trying to frame the ball visually are only two-dimensional. They are flat, and give no reference points in their system, making them visually dead, or very insensitive to incorrect eye position at set up.

The first and only way to do this correctly in three dimensions is the 3Dinsight™ solution, making our unique system proactive and very discriminating to incorrect eye alignment and stroke path. This system continuously communicates to you by what you perceive in the peripheral vision. The visual part of the brain is very critical to the detection of parallel lines. This system is one of the very few being totally parallel, so dominant eye issues are non-present in the 3Dinsight™, very important to ball position at set-up and true loft at impact.
