Description
The Praktica Marine Charter 7x50 Blue binoculars are so-called marine binoculars, which have a number of advantages. In addition to complete waterproofing and nitrogen-filled housing, all marine binoculars must have a bright, noticeable housing coloring so that it can be easily detected if dropped in water. At the same time, the straps of such binoculars do not sink. Low magnification allows for a wide field of view, high light intensity, and promotes image stability even when observing from a boat rocking on the water.
Like many of the world's leading optics manufacturers, Praktica was until recently better known as a manufacturer of high-quality cameras. Founded in 1949 in Dresden, East Germany, the company has produced over 100 different camera models, and continues to receive awards for innovation and product quality. Today, Praktica has expanded its product range, successfully using its many years of experience in developing optical devices, Praktica has taken its rightful place among manufacturers of top-class sports optics.
The main advantage of the Marine Charter 7x50 Blue is its complete moisture and dust protection. The IPX7 waterproof class provides water protection at a depth of 1 meter for half an hour. A wide and comfortable strap will stay on the surface of the water, preventing the binoculars from completely submerging. Internal filling of the housing with nitrogen prevents fogging of the optics from the inside and internal corrosion.
The binoculars have a fairly massive body for installing large Porro prisms, but weigh only 1 kilogram, being one of the lightest in its class. Large prisms in combination with wide-angle eyepieces provide a wide field of view, stereoscopic images, and do not cut off the light beam. Full multi-layer enlightenment in green and violet tones has a high intensity and contributes to maximum light transmission.
