Message: <blockquote data-quote="Kevin Purcell" data-source="post: 1321831" data-attributes="member: 68323">Weird coincidence. Frank mentions cryptically he's found another open-bridge ED bin then he starts the Vanguard EDT thread. At the same time I was making a comment on another thread about Bosma being a major OEM for Vixen these days and wanted to add a link to their web site. So I google to find the site then I can't help but click on the bins link. And there they are ... three new 8x42 ED bins.<a href="http://www.bosma.com.cn/en/lbinoculars.asp" target="_blank">http://www.bosma.com.cn/en/lbinoculars.asp</a>They're all wide angle (8.1 degree) FOV roof bins with 42mm ED objectives. That's the same FOV as the Hawke ED.The first two (303317 and 303322) have identical optical specs but the 303317 is an "normal" "closed-bridge" design whereas the 303322 is an "open-bridge" design which seems to have more rubber on it than the Promaster or Hawke. They both have a rather unusual "trumpet-like" flare at the objectives.The third one is another "open-bridge" design with slightly different optical specs and more "bare metal" frame exposed. I think it's powder coated metal like the Promaster or Hawke but unlike say the BushnellElite which seems to have exposed oxidized Mg). I suspect there is a single maker out there making the magnesium open-bridge enclosure as these are very similar (with some cosmetic changes) to the Promaster Infinity Elite ELX ED and the Hawke Frontier ED. Even the little details look similar (but not identical) to those bins: the diopter setting is different in all these bins: some like the Hawke; some like the Promaster. The focus knob is similar.Dimensions and weights are not given in the specs so it's difficult to tell if they're the same size as the Promaster or Hawke EDs but given the latter two are the same size I suspect these are too.10x versions of each are available. See the web site for specs.<a href="http://www.bosma.com.cn/en/productgn_info.asp?id=976" target="_blank">http://www.bosma.com.cn/en/productgn_info.asp?id=976</a> Item NO.    303317Model    8X42Power    8XObjective Diameter    42 mmPrism system    RoofRrism glass    BAK4Focus system    CenterF.O.V.
