My Swift Ultralite 8x42 binoculars may be out of alignment. When I focus on a distant hawk or duck, I find myself closing one eye, because otherwise I see double images.
They were bought in 1993. I do wear bifocals while using them.
I would like to have them repaired if possible.
Cynthia Powers from Indiana
have asked about the most common binocular problem: double imaging. As you clearly know how to correctly operate and adjust the eyepieces there are two very common causes as detailed below.Your
binoculars either have a bent or broken yoke assembly (the bit which
carries the eyepieces) or one or more prisms have came unseated.The
first repair involves replacing the entire yoke assembly: the part is
expensive in comparison to the retail cost of a new pair of binoculars
and with labour charges on top is not usually a cost-effective repair
except on higher end expensive models such as your Swift Ultralite 8x42's. Note that if bent or broken then repairing the part is not feasible: if broken the area to be glued is too small to carry the loads afterwards, and has usually bent before breaking anyway, so you just end up with a bent yoke which cannot be straightened. If merely bent, then the yoke is difficult to accurately straighten and the bending causes fatigue cracks which will eventually break.The second repair is
straightforward and fairly quick for anyone with the right collimation
equipment, but the screw(s) need to be secured with thread-locking
liquid afterwards.Both of these causes are caused by dropping or mishandling the binoculars, so the Swift warranty will not apply. For details of where to get your Swift binoculars repaired, contact the manufacturer directly on 877 MYSWIFT or 877 697 9438.I
