Have a weird bow issue

I have two bows, exactly the same. First one i hog the center circle. Second one is inconsistent 8 inches up and down.
Same arrows, same release, same brand of bow, same brand of sight etc.
Laser both and seem setup correctly.
Any suggestions?
 
I would take a look at the arrow fletchings. Check for wear. They could be contacting the arrow rest, riser, or bow sight causing inconsistent flight. If that's not the culprit, if it's a dual cam bow check to make sure your cams are in sync. If not that can also cause the problems you mentioned. If all else fails, check the small stuff like bolts you may have forgotten to snug down on the arrow rest or on the sight.
 
As mentioned above, make sure you don't have fletching contact, then play with nock height. If you have fletching contact problems, your rest is probably dropping too slow, or rebounding.
 
Quick way to check for fletching contact is take your wife’s lipstick and just barely touch the edge of your vanes. When you shoot it it’ll leave a small mark wherever it is making contact. Could be a timing issue but I’ve found they will still shoot somewhat consistent out of time. That large of vertical variations tends to be a rest timing issue. What brand and model of bows.
 
I had the same issue a few years ago and realized my rest tension, (using a drop away), required adjustment. It wasn't raising all the way causing the fletching to hit the shelf and once that happens the arrows would either go high or low. Like previous posts --check fletching contact and let us know the solution.
 
Replaced the rest with the one from my wifes bow, shortened the variation. Whats the best way to check timing? Video camera?

I use a draw board. It’s tricky getting it to stop without pushing the cable till the other stop hits pulling by hand. Unless it has limb stops then draw and have that person tell you which is hitting first. That the beauty of draw board. Infinite adjustments to see exactly when one contacts the cable/limb
 
Trying to get advise over the internet on bow setup is like diagnosing a cough via WebMD. You could have allergies or lung cancer.

A good tech can figure most issues out in 5 minutes, and fix them in 15. Take it to a shop, or learn to work on your stuff at home.

Draw board. You can DIY one pretty easily for about $40-50 with a 6ft length of 2x6, 6" lenght of metal pipe, pipe flang, ratcheting boat wench, and a metal carbiner to clip into your D-loop.

Hook up the bow and start pulling it back. Once the cams start to rotate over you can check timing via the timing marks/holes on the cams. Will need a bow press to correct cam timing issues though, unless you have a draw stop that is set incorrectly on a cam.
 
So i figured this out. I use ultranok instead of a string d loop. This is because of my release. I figured out that on this ultranok my release was hanging. Replaced the ultra nok and boom bobs your uncle. Thanks for all the suggestions and help... i learned alot about my bow during this process
