Why You Choose Our ED Glass Binocular
- PREMIUM ED OBJECTIVE LENSES: Extra-Low Dispersion (ED) glass
virtually eliminates chromatic aberration or color fringing, a
visual defect common in binoculars. You'll enjoy razor-sharp images
with outstanding, true-to-life color.
- VERSATILE, ALL-AROUND BINOCULARS: These premium binoculars are a
great choice for birdwatching, nature observation, the trail,
stadium, arena, or anywhere you want a close-up view of the action
without sacrificing brightness or detail.
- BaK-4 PRISMS FOR OPTIMAL VIEWING EXPERIENCE: The prisms inside ED
feature quality BaK-4 glass with phase coatings applied to maximize
light transmission and enhance bright, highly detailed images –
especially in low light conditions.
- DURABLE, WEATHER-RESISTANT BODY: A rubber-armored, polycarbonate
housing protects your binoculars from damage and stands up to even
the toughest weather conditions! They're also fully waterproof
& nitrogen purged to prevent internal fogging of the lenses.
