The SP is a simple profile that maintains a constant stimulant (shape) for your eye – it works in your peripheral vision and not as a sight but as a trigger effectively guiding which eye is used to help you position the gun.
Its sole function is to gain the attention of the eye over the rib in your peripheral vision during the setup and with the barrels will give you a strong reference to the correct barrels – ultimately leading to better more consistent shooting.
The SP is visible to one eye only (e.g. Right eye for right-handed shooters) creating a visual reference in your peripheral vision for the correct barrels, you will go on to develop the shot with this information naturally. This will allow you to shoot with 100% focus on the clay- keeping both eyes open throughout the shot.
The lead picture will be from the eye over the rib, giving you consistency and confidence on every shot.
The SP starts to work as soon as you begin your set up engaging the eye without your knowledge- your only job is to ensure the SP is in your peripheral vision during the setup. As you call PULL the SP will have done its work and you can shoot naturally without distraction.
