You might want to know that every PRIME HD binocular has gone through rigorous waterproof testing before leaving Zen-Ray's factory floor by following the most demanding JIS 7 (Japanese Industrial Standard Level 7). What does that mean? They immerse every binocular into a 5 feet deep water tank for 3min. Only the ones that pass the test can be released. So, let it rain!

      5.0 Excellent


      Quality Lenses



      I have some pairs of binos, like Nikon Monarch 5, Zeiss Conquest and Vixen Foresta. This pair is the best. There is no CA. (just minimum at the edge, if you look for it) and the image is sharp from edge to edge. It's perfect, except for the distortion at the edges.

      Bottom Line: Would you recommend this item? Yes
      Was this review helpful? Yes / No
