The Nikon EDG 10x42 model binoculars include a 10x magnification rating and a 42mm objective lens that provide an overall field of view of 114 meters at 1000 meters away. The Nikon EDG 10x42 model is also completely waterproof up to 16.4 feet for a 10 minute maximum time limit.
The Nikon EDG 10x42 model binoculars also include additional features such as specific Nikon lens technology, turn and slide rubber eye-cups, a "roof" type glass prism, a dual focus adjuster knob for both eyepieces, and a body made up of environmentally safe materials. Nikon claims the EDG series binoculars are designed with a durable body design to last in a plethora of conditions. The 10x42 is also equipped with a high eye-point view design to allow users with prescription glasses the opportunity to use the binoculars clearly as well.
What separates the EDG 10x42 model from other models in the EDG series is the unique horn-shaped eye-cups that are designed to fit to the users face and block out peripheral light, mid size body design making the model more portable, and an upgraded neck/shoulder strap that Nikon claims has been redesigned with much lighter materials.
Nikon claims that the EDG series of binoculars are professional grade and will provide superior quality in both picture and durability hence the higher price tag, however the models fit right in with other higher end binoculars.
