Viper binoculars - 03/06/2012

by JAH from Adirondacks of NY

I bought these just prior to a vacation to Belise and I am so glad I did, Tucans, Parrots and hundreds of other exotic birds were crystal clear. I would highly recommend these binoculars.
They were easily packed and portable, light weight, easy to use and phenominal optics. From Laughing Falcons, to Dophins, the binoculars were the best. I will have these for my lifetime and will be carrying them much more than my previous binoculars which were too bulky and heavy.

higher power quality compact - 02/09/2012

by Alan Birnbaum from Fresno California

The Vortex Viper 10 x 28 has excellent mechanical, ergonomic and optical qualities. At 12 oz. it feels almost weightless on the neck. Eye relief is very generous. The relatively large focus wheel has a smooth and backlash-free action. While the field has only standard coverage, it is very flat and free of edge curvature. Overall it resembles my Pentax DCF SP 10 x 43, with a somewhat narrower field and half the weight.

I opted for the 10X version since I will be using it frequently to check our local system of drainage ponds, rather than walking through wooded areas, and plan to keep it in my car, though its compact size will make it suitable for trips by air. Most users, however, would do better to opt the 8 x 28 version. The Viper 10 x 28 won't be my binocular of choice for an all day birding trip, for which I have several larger pair, from Pentax, Swarovski and Canon, but particularly an older person might do fine with the Viper, especially in the 8X version, as their sole pair of binoculars, and it would also work nicely for a traveler.
