Vortex Optics also included a Porroprism design, coupled with BaK-4 prism glass for maximum clarity and light transmission.
The inside of the scope is nitrogen purged, giving it that maximum fogproof feature. The Vortex Optics Diamondback Spotting Scope is waterproof as expected, as the lenses are O- ring sealed.
Sleek contours make the scope sit in your palm firmly and securely. A central focus knob is ergonomically placed on a spot where your palm would naturally rest, so focusing those shots is done in an instant.
