Ideal for longer-range glassing needs on land and water, the Opticron 10x42 Oregon 4 PC Oasis Binoculars feature proprietary phase-correcting prism coatings and reflective prism surfaces that maximize light transmission and boost clarity and contrast. The prism coatings are complemented by anti-reflection fully multicoated optics which provide bright, clear, high-contrast views with accurate color rendition. The 42mm objectives gather all the light needed to keep views crisp and bright in challenging conditions, such as at dawn and dusk, without being overly bulky or cumbersome. Their chassis is nitrogen filled and O-ring sealed to be resistant to internal fogging and waterproof to withstand extreme weather, with textured palm pads on the armor to ensure a secure grip in cold and wet weather.

Q: 5. what about with eye glasses? would it be comfortable when wearing them?

A: My wife and I both wear glasses and they work ok., just a little smaller field of view. They will focus if I take my glasses off with my -8 diopter correction.

Q: 6. I bought one of these very heavy binos. Used it a couple or 3 times on my Manfrotto t-pod. They are so heavy that, on the 4th or 5th nite, they stripped the threads off of the socket & it hit the pavement. This knocked both tubes out of alignment! At least the only external damage - to one tube - was an extremely small ding & a scratch or 2. STW - does anyone know of repair shops that do realignments? I'm in the Boston, MA area.

Q: 7. I have a Celestron 25x100 binocular that came with a Celestron Alt-Azimuth tripod Model 93607 but they don't seem to mate very well and the tripod does not elevate more than a few degrees above hrozontal. Do I have the wrong tripod?

A: I have the same binoculars and tripod. The mating to the tripod is very solid; no problem at all. Perhaps you've sorted that out by now. The range of elevation angles is somewhat limited from what I'd prefer. It's about plus/minus 20 degrees. However, anything more could make it very awkward to sight through the binoculars.

Q: 8. Are the case and lens caps included, as the "in the box" description says?

A: Yes. The Nikon 8x25 Travelite Binoculars come with the eyepiece caps and the case.

Q: 9. Trying to confirm that this item includes an interface to mount to a tripod?

A: I believe so as I just screw mine directly to a camera tripod. I didn't have to purchase any adapter or extra parts.

Q: 10. Are these binoculars waterproof?

A: No. They are not waterproof or fog-proof.
