Hawke Nature Trek ED series is offering quite a lot for their affordable price. Because of ED glass, which has been used at lens manufacturing, the dispersion of light is essentially smaller, which makes excellent optical properties like resolution and contrast. Very accurate manufactured lenses are coated with multi-layer coatings, which enable even more contrast and higher resolution of the image. Also because of a large diameter of entry lens, the spotting scopes from this series will not let you down at the dusk or low light condition. The scopes are made as water-resistant and the fear of using it at extremely damp environment is in vain.
