the one to buy


from Kenedy,Texas  -  Avid Adventurer

very clear not to heavy really good birding binoculars I have bought several pairs of binoculars and this is the best.Not really expensive for the quality and performance. Look forward to really putting to the test.


Tremendous clarity, focus and depth!


from Northern California  -  Avid Adventurer

As soon as I received these I was able to see a great horned owl in my neighbor's tree, 50' up, clear as though with the best telephoto lens! Then, an almond orchard, half a mile a way, in bloom, was an astounding sight. Best binoculars I have used. Couldn't be happier with purchase, Adorams price and speed of delivery!

from Chesapeake, VA  -  Casual/ Recreational

These binoculars are my first quality glasses. I purchased them after my current pair broke (not Vortex). The specs on the old pair were also 10 x 42 but the Vortex glasses are much brighter and allow a closer focus than my old pair. The solid construction appealed to me. The price was right[...]t. A+ to Adorama and Vortex.
