Sight Alignment Trainer & Eye Dominance Tool

New shooters struggle with understanding sight alignment and eye dominance.  Many “seasoned” shooters struggle with the same issues, especially eye dominance.  Asking someone to make a quarter sized hole between their hands and then determine eye dominance is sometimes like asking them to stretch their lower lip up to their eyebrows.  Here's a how-to for eye dominance:  https://my.clevelandclinic.org/health/articles/dominant-eye

The sight alignment trainer allows you to teach “equal light, equal height” and have a device to demonstrate.  The Eye dominance tool forces shooters to focus on the distant object within the quarter sized hole in the plate.  

The sight alignment tool has swappable disks to allow you to select your “dot” color or use black for dotless sights.  The disks are designed to snap in but if they become loose add a touch of glue to the edges.  

You are welcome to do with this what you wish.  Make improvements upon it and sell it to people or print a batch out for your next firearms course.  Happy capitalism!
