As the name suggests, the Delta Extreme 7x50 ED finder scope has a special place among finder scopes. With a thick reinforced rubberized aluminum die-cast housing, premium quality lenses polished from precious ED glass material deliver a uniquely contrasty, crystal clear view. All elements of the Delta Extreme Series lens system have multiple layers of anti-reflective coating, which ensures 90% light transmission through the ED lens material and large prisms.
The Delta Extreme 7x50 ED binoculars have a side-by-side focusing system instead of a central focusing system, making the binoculars more durable, water and dust resistant, while not losing focus as easily as binoculars with central focusing. The rubberized exterior not only protects the scope from damage, but also provides a very good grip even in harsh weather conditions. The finder scope will not let you down even at -40 to +70°C. With its huge 7.5° field of view, it offers excellent image quality even at the edges, even in twilight conditions. These qualities make the Delta Extreme family of binoculars the preferred choice for a wide range of applications, including astronomy, law enforcement, military, marine and hunting .
The binoculars come with a handy hard carrying case and lens protection caps, of course, as well as a comfortable neck strap.
