As the name suggests, the Delta Extreme 10x50 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 10x50 ED finder telescope features side-by-side focusing instead of central focusing, making the telescope more durable, water and dust resistant, while not adjusting focus as easily as a central focusing finder telescope. 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.
