Tasco Binocular 40x70
Porro prism - this design has proven its functionality for more than 100 years. In the binocular box, 2 Porro prisms are used to extend the path of the light beam, allowing for larger magnifications. The Porro Prism binoculars offer extremely high optical quality at more affordable prices than the roof prism binoculars at the same power level.
Fully Coated - all surfaces of the lenses that are in contact with the air are covered for even clearer viewing. Because glass surfaces reflect back up to 4% of any light passing through them, binoculars made without an anti-reflective coating on the lens surface make the image poor and dark. Most of the higher-quality binoculars have all or most of the vacuum lens surfaces treated - layers of magnesium fluoride and other exotic elements to reduce the loss of light from the reflection - which increases the light transition and makes it brighter and clearer Image.
Convenient to hold rubberized cover.
Rubber lens and eyepiece protectors that protect binocular optics from transport and storage injuries.
Correction of the diopter.
Bracelet carrying strap.
A special cleaning cloth for the binocular optics.
An additional lens protector.
Comfortable shoulder bag.
