Binoculars Double image - Collimation?

Hi Everyone!

Today is my birthday, and I was lucky to receive a pair of Andrews 15x60 binoculars. Our family now have several pairs of these binos and they really are great value for money!

However the pair I received see a long way out of alignment. The image through each EP is good however they don't point exactly at the same object, and my eyes can't merge the image.

When I line up the left eye on an object, the right eye is 25% of the FOV to the right. When both eyes are open I see double images.

There doesn't seem to be any adjustment screws for the prisms just a spring clip which holds them in place.

Does anyone have any idea of how I can fix this myself or should I be sending them back? I'd rather not pay for more postage....

Any help would be great!

Cheers,

David.
