Product Description

FMC multi-layer high transmittance green film
High light transmittance, effectively reducing the refractive index of light, resulting in clear, sharp and transparent imaging
Built-in Tripod Adapter
Built-in tripod mount makes the binoculars perfect for viewing distant objects, even the sky, you can mount your 80mm binoculars on any conventional photographic tripod. Tripod adapter for steady, hands-free viewing; stabilises your view for added comfort and shake-free viewing.


80mm Large Objective Lens
The field of view is wider with 80mm large lens than it is with 70mm. In low-light and long-range situations, 80mm fully multi-coated lens and BAK4 prisms ensure greater light transmission, bringing you crystal clear views with higher contrast and less color errors and distortions.
177ft Field of View
177ft field of view at 1000 yards gives you a wider field of view. Easier to see fast moving objects.
