Tough, portable and manufactured from precision polycarbonate and alloy, Steiner's compact Wildlife Pro binoculars are built to handle the world's harshest conditions, yet offer clear, bright and precise viewing in a very small body design. The Wildlife Pro models are wrapped in a smooth, quiet and non-reflective earthtone rubber armoring that makes them almost invisible to wildlife. At only 11 ounces the 10.5 x 28 Wildlife Pro compact is just one ounce more than the 8.5 x 26. When you need added power for long distance viewing but can't be weighed down, the 10.5 x 28 is an excellent choice. Fully multi-coated optics and phase corrected roof prisms provide excellent color reproduction with brilliant clarity. Fast and precise center focusing make adjusting quick and easy. The 10.5 x 28 is water resistant and shockproof. Weight: 11 oz. Field of view: 264 feet @ 1000 yards. Eye relief: 13mm. Dimensions: 5.2" L x 4.4" W x 1.8" H. IP (Inter Pupil) Distance: 57-73mm.
