Manufactured with highly resistant materials and coated with a special rubber varnish, the Delta Extreme range has an individual focusing system.
The binoculars are available in four magnifications and two types of bells (7×50, 10×50, 10.5×70 and 15×70).
This powerful optical instrument is ruggedly built and uses the latest optical technologies.
They are made with high quality multi-layer FMC coatings covering all lens elements and, perhaps most importantly, lenses made of ED glass with very low dispersion and a diameter of 70 mm , which collect twice as much light as classic 50 mm lenses. ED glass eliminates chromatic aberration and increases overall image sharpness.
The image of the Delta Extreme is sharp over the entire field of view and free of aberration, which means that the viewer perceives all contours as very expressive, and small details are visible, unattainable in lower class equipment.
