3rd Axis
I'm presently shooting a Cooper John Pro11 on my Max 3000. I've been looking at there Pro111 w/3rd axis. I can't seem to find any info about the set-up. Anyone know where I can down load set-up instrustions? Also explain the advangaes and purpose of the 3rd axis? If I'm not mistaken is it suppose to eliminate any yardage ajustments for up and down shots? Does it really work? Jerry

RE: 3rd Axis
Jerry.
There are set up instructions for the 3rd axis on Spot Hoggs web page.
Here is a copy and paste of what they say.
1. Hang a plumb bob from your ceiling.
2. Nock an arrow
3. Kneel down (so that you will be shooting uphill)
4. Draw back, and aim up toward the plumb bob and align your vertical aiming wire to the plumb bob. See where you level is.
5. Let down, and make an adjustment to your 3rd axis (the object is to try and get your wire lined up with the plumb bob and your bubble level).
6. Redraw to see how close your adjustment is.
7. Repeat steps as necessary.

Here is what they say about the 3rd axis.
Another copy and paste.
3rd axis leveling
3rd axis leveling is the squaring of your level, so that the bow will be held in the same vertical plane for flat, uphill, or downhill shots. If your 3rd axis is not properly set, your level will lie to you, causing you to cant your bow when shooting up or downhill. Resulting in left and right arrows, no matter how good you executed your shot.
Leveling your 3rd axis must be done at FULL DRAW. Bow vises and bench jigs are not accurate because they don't take into account the torque in the bows riser when it is drawn. A sight that is squared at rest will not be square at full draw, when aimed up or downhill due to the torque in the riser. Both the Hogg-It and Hogg-It Hunter models have a 3rd axis adjustment that allow you to level up your sight without the bothersome task of trying to shim your bow mount.

RE: 3rd Axis
Thanks Ausie. What a great site. I found the info I was looking for plus more in the news letters. I'm going to change over to the pro 111 this week and see if it makes a diference for me. The logic makes sence but I'm not sure if my shooting ability is equal to the task. I'll let you know. Thanks. Jerry
