"Bresser Spektar spotting scopes are smaller in stature than the Pirsch models, but that is not necessarily a bad thing! When you are on the go or have a long hike ahead of you, it is nice to carry equipment that doesn't weigh you down. The Bresser Spekter 60 weighs just under two and a half pounds, has a zoom magnification range of 15X - 45X and is waterproof as well, giving you an additional layer of security when conditions are damp or the weather turns. The 60mm optics are large enough to deliver bright images in all but the deepest low-light conditions and the lenses are fully multi-coated (FMC) for high light transmission and clarity. A cool feature of the Bresser Spekter 15-45X60 is its fully rotatable body, which allows flexibility in angle positions. The ability to rotate the Spektar 60 spotting scope is especially useful when hunting or looking at astronomical objects. In fact, if the subject has a tendency to move at all, you'll love being able to make adjustments of this nature."
