Product QuestionsWE ARE LOOKING FOR A GOOD BINOCULARS FOR BOTH TERRESTRIAL AND SKY OBSERVING USE IN COLORADO.
FOR THE MONEY, WHAT IS THE BEST VIXEN PAIR OF BINOCULARS? ALTHOUGH THERE IS A DISCOUNT HERE IT DOES
STRETCH OUR BUDGET. THANKS, SHANNON COX (512-413-3500)Question by: SHANNON COX on Apr 14, 2015 4:53:00 AMIf you need to have the option of adjusting the magnification of your viewing, then this is the best option. The 80mm fixed power Vixen BCF binoculars are less expensive, but the power can not be adjusted and the zoom BCF binos are not as sharp as the higher end BT81 model. There isn't really a comparable product around this price point, so the BT81 is a good choice.Answer by: Chris Hendren (Admin) on Apr 14, 2015 3:33:00 PM
