PelaPapas Report post Posted September 14, 2015 I am looking to buy myself a used pair of Kaibab 15's. Is there any difference in the older models vs. the newer ones? The only thing I see different are the boxes/packaging. Other than that they look to be exactly the same. Binos themselves look to be the same. Would I be ok with picking up an older pair? Both HD glass and same in all aspects? Any input is appreciated... Share this post Link to post Share on other sites
