Message: <blockquote data-quote="RJM" data-source="post: 1834383" data-attributes="member: 66340">Doh!Last week I made a very successful birding trip to a tiny island 50km offshore in the Sea of Japan and the HD's performed wonderfully including a day spent walking around in the rain. :t: However, upon my return I noticed the left twist-up eyecup assembly had mysteriously come loose and was literally hanging by a thread. No problemo I figured to simply thread it back on.  WRONG! Somehow, through not paying close attention and not realizing the assembly threads on counterclockwise, I bunged it up and crossed-thread and locked the assembly down tight onto the eyepiece totally cockeyed with eyecup pointing inward. No amount of twisting/turning would let me remove it!:gn:  But while it looked stupid at least it did not affect the view so figured I would wait to send it Bushnell during my next trip back to the USA. Plus I still had the backup Ultra HD that my wife uses.8-P However, I was lucky to find a cheap rubber strap/belt wrench (a UK import too!) and with the help of some friction tape to prevent slipping I was able to remove the twist-up assembly. Amazingly, I did not seem to damage any of the threads so I could now carefully reassemble the eyecup correctly. Yay!:king: FWIW, the entire assembly is made from metal, NOT plastic, while the rubber guard is glued on to the twist-up part. By using a small flatblade screwdriver to CAREFULLY work in between the metal and rubber, it is possible to seperate the rubber from the metal without tearing. The twist-up component is held in place by 3 brass guide screws. For anyone complaining about TOO MUCH eyerelief I think it would be possible to slip an O-ring or two over the ocular to raise the assembly, thus the eyecups, further away from the lens and shortening the eyerelief. Just make sure you have the tools and some glue! Rick</blockquote>
