Short Description of Delta Optical Extreme binoculars
The Delta Optical Extreme series offers the biggest and one of the most powerful binoculars with Porro prism system on the market. Large variety of binoculars in this series are suitable for marine use, hunting, military, navy, law enforcement and astronomy applications. Even though these binoculars use Porro prism system, they are upgraded with modern optical innovations. The construction is wrapped in rubber armor to protect them against different impacts and rugged surface provides you with a non-slip grip although it’s recommended mounting them to a tripod, since they are much heavier. Optically the Extreme series offers incredibly high light transmission rate with the help of FCM multi-coated system on ED glass surfaces with razor sharp images free of major distortions from edge to edge. These binoculars are also waterproof and fog-proof due to nitrogen gas purging and tight seals and will not get damaged even when used during harsh weather conditions and can operate in temperature range from -40 to 70 °C. To make proper focus adjustments, the Extreme series is equipped with individual focusing mechanism, that also helps to make them more impervious. Eyepieces have only one position but longer exit pupil distance helps to give a proper eye-relief even for eye glass wearers.
