The new Travelite V series binoculars incorporate several new features designed to make them more user friendly while enhancing optical performance.Nikon Travelite V binoculars utilize precision ground, multicoated optics, and high index BaK4 prisms for true color rendition, maximum sharpness and enhanced light transmission. The new binoculars use aspherical eyepiece lenses which provide a very flat viewing field and offer markedly improved edge-to-edge sharpness over many conventional lenses.The new Travelite V features large, conveniently located central focus knobs and clicking diopters. Each model in the series features 25mm objective lenses for maximum light gathering.A new, ergonomically contoured, carbon-fiber body makes the Travelite V easy to use for long viewing sessions without physical fatigue. The lightweight body incases a rugged all-metal chassis and is covered with a durable black rubber armor that provides added shock resistance and a positive grip in slippery conditions.
