PRODUCT DESCRIPTION
Action Extreme 7x50 ATB binoculars provide impeccable magnification for all your outdoor needs.
(This product has been archived)
The secret is the 7.1mm exit pupil (the diameter of the light hitting your eye). It is physically impossible for the human eye to take in more light than this provides. If you're on a boat at dusk or scanning a dark forest floor, these will actually make the image look brighter than what you see with your naked eye. Plus, at 7x magnification, they are incredibly easy to hold steady on a moving deck.This special appliance features aspherical eyepiece lenses. Most people don't know that this prevents the "fishbowl" distortion at the edges of the frame, which is a common problem with large 50mm binoculars. It keeps the horizon line perfectly straight—a must-have feature for boaters!Perfect For:
- Oceanic Gazing
- Overland Gazing
- Extreme Low-Light Forest & Marine Navigation
- Stable Viewing on Moving Boats & Decks
- Enthusiasts & Beginners
