Quality glass at an affordable price.


from Saline, Michigan  -  Casual/ Recreational

My brother has a set of Alpen binoculars,and I was impressed with how clear they are, and how reasonably priced they are for the quality you get. Not to be outdone, I also got a pair. To date, I have only used them to check out the ducks and geese flying in the neighborhood, and am very pleased with my decision. I look forward to using them for deer and coyote hunting in the coming seasons.
