Third axis.

So I had a bow shop do my third axis on my new sight. I kinda wish I would have paid attention because I have never done I before and would like to know how. I don't hunt tree stands so I have never really had a use for it but I figured it would help out with long downhill shots here out west. Does anyone know how to adjust the third axis and a way to check it. I have a black gold ascent verdict sight btw.

LAST EDITED ON Dec-22-17 AT 09:02AM (MST)[p]I am wondering the same thing. I have the same sight and didn't even realize I had a third axis

I bought a Hamskea 3rd axis leveling tool for adjusting mine. Nice to have since I tinker with setups often. I'm not sure how someone else can adjust it for you because how you grip the bow will skew the results to some extent.

I've always set the first and second axis and then you need to draw your bow for the third axis. Get a door frame or other perfectly 90 degree object with a definite line and then line up your pins with that line as you lower and raise your bow. That entire time your bubble should remain level, if not adjust till it is. Third axis is then set.

I used a plumb bob and a little heavier string to set mine up. Hang the string from the ceiling if your inside or from a tree or other high point outside. Draw, anchor and bend at the waist up and down. Your bubble should stay centered. Not sure how to adjust on that particular sight

One of the better explanations I've heard:

Technically, having a level is the problem, as it is the only thing that will show you the "symptom" of the 3rd axis being off. The entire exercise of 3rd axis leveling is to ensure that your level is accurate at various angles.
Imagine if your pin housing angled away from the shooter at a 45 degree angle off the mounting bar, rather than the typical 90 degrees (so the left edge of the pin guard was farther away than the right edge for a right-handed shooter). If the bubble level was perfectly adjusted at horizontal (bubble dead center) and you aimed the bow uphill, the bubble would run away from the shooter (to the left for a right-handed shooter) as that side of the level would be the high point. If you aimed downhill, it would back toward the shooter (to the right for a right handed shooter) because that side of the level would be the high point. 3rd axis adjustment allows you to adjust the sight so it is dead nuts at any angle. You do this so you can still rely on your level regardless of shot angle.

On sights with levels but no 3rd axis ajustments, you would need to shim the sight where it connects to bow's riser in order to make this adjustment (make the mounting bar come off slightly right or left from the riser).

BUT In my opinion, most shooters/hunters are not consistent enough to show a dramatic difference to make 3rd axis adjustment worth their time in the field....if theyre using their bubble at all.
