The 20x70 Echelon Binoculars from Celestron are large-objective binoculars featuring a fully multicoated optical path and a weather-resistant housing. Celestron's XLT lens coating helps maximize light transmission and improve image contrast. Individual-focus eyepieces allow the viewer to set the focus depending on their eyesight. A nitrogen-filled aluminum alloy housing provides fogproof and waterproof performance and non-slip rubber armoring helps maintain a secure grip in wet conditions or while wearing gloves.
