Hi Kerosene (or is it Roger??),
Yes, this is fairly easy to do to collimate them. (you just need to "screwdriver one" side of them
Also, I have had the same problem with my 11x70 Andrews ones, they were bumped out of collimation when I took them to China with me.
1) Push the rubber grips down to see where the collimation screw is on each side. You will need a small flat blade jewellers screwdriver.
2) Start with one side only as you will probably find that only one side is out.
3) Look at an object fairly far away, I use a church steeple which has a nice and handy cross on the roof
4) When you see double, keep your left eye as the reference and then turn the right side screw a couple of turns to see which way the image shifts.
5) After a few turns, you should be able to see which way you need to go. When you get really close, you might find you may need to tweak the other side a little bit, however, I haven't had to as the bump only caused the right side to shift.
See how you go, just be careful not to turn too far, the prisms are made of glass after all.
I think these designs may be susceptible to this problem, however the price is a lot cheaper than the dearer ones which I think probably don't have this problem.
It should be something you can sort out yourself, keep in mind this is supposed to be able to be done by the owner, so even if you can't sort it out, let Andrews know and they should fix it for you or replace them. They did just that with my first set and had no objections to replacing them.
I hope this helps.
Cheers
Chris
