The Viper HD 6x32 Roof Prism Binocular from Vortex Optics is an argon-filled, high end waterproof and fogproof optic that presents a relaxed, wide view in a small instrument. The 8deg. field and 6x magnification make this an extremely easy binocular to use for anyone of any experience level, even children.
It would be a good choice to wear on horseback (with a harness strap). Its close focusing capacity, to just 3', makes the HD 6x32 Viper perfect for observing butterflies. This is Vortex's highest class midsize unit, with HD (High-Density) extra-low dispersion glass objective elements to provide the highest possible edge-to-edge resolution and color alignment.
