The Nikon EDG 10x32 model binoculars include a 10x magnification rating and a 32mm objective lens that provide an overall field of view of 114 meters at 1000 meters away. The Nikon EDG 10x32 model is also completely waterproof up to 16.4 feet for a 10 minute maximum time limit.
The Nikon EDG 10x32 model binoculars also include additional features such as specific Nikon lens technology, turn and slide rubber eye-cups, 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.
What separates the Nikon EDG 10x32 model from other EDG models is the integrated thumb indents on the underside of the body for a better grip, unique Nikkor lenses which help eliminate chromatic aberration (failure to converge all color types on a single point; cause blurry images), and a waterproof/fog proof body design.
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.
