Delta Optical CHASE 12x50 ED

Carefully selected high-quality types of glass and a newly designed optical system help ensure that the binoculars from the Chase series offer significantly better image quality than binoculars in a similar price range.
Allen binoculars in this series use lenses made of ED glass with low dispersion. Lenses of this type guarantee a low level of chromatic aberration while maintaining a reasonable size. The binoculars have a large field of view that is significantly better corrected than the previous models.
The entire construction is made as a roof prism with internal focussing. The case is very robust and of course completely waterproof.
The binoculars of the Chase series offer an image with a very high level of detail and splendid coloring.

Not only are these excellent daytime binoculars for hunting, used for detecting the antlers of game, they are also universal binoculars for those who expect a high-precision image. The binoculars are almost free of chromatic aberration and have a relatively large field of view with good image sharpness almost to the edge. Despite a large magnification, it is a comfortable and not too heavy model, as it only weighs 890 grams.
