Third Axis Calibrator (TAC)
The simplest and most affordable way to check and correct your bow sight’s 3rd axis at home.
No more guessing at steep angles or paying for a pro shop tune-up. The TAC lets you quickly and accurately check your sight’s 3rd axis alignment in your own backyard. Just attach it to your sight, draw your bow, and look in the mirror to see exactly what needs adjusting.
How It Works
- Attach the TAC to your sight housing using the included bungee and tensioner
- Draw your bow back with an arrow nocked and anchor properly
- Level your sight bubble and look through the acrylic mirror
- If your pins line up with your string in the mirror — your 3rd axis is perfect
- If the pins are off to the left or right, simply rotate your sight:
-
Clockwise if your pins are to the right
-
Counter-clockwise if your pins are to the left
