We finally released the newer PRIME HD spotting scopes. They are on the website now. The main optical system of the body is identical to original ZEN ED2 system. However, we have made several sigificant changes with the new spotter
1) The 25-50x kit with aspheric lens in the eyepiece available.
2) Cyrstalview (Hydrophobic coating) is standard on the eyepiece
3) Change the orientation of the tripod foot 90 degree to make it compatible with widely available Manfrotto 128RC tripod head
4) 2nd generation Dielectric coating as used our PRIME HD binoculars
5) The rugged looking exposed Magnesium body now has a newer, smoother finish. It feels like velvet or suede it if I try my best to describe it.
Of course, individual star testing of every unit is by default per our standard.
Out of numerous other quality improvements with the new spotter, what I am most proud of is the new 25-50x PRIME HD kit.
