60mm objectives gather 30% more light than 50mm models (surface area = pi*r²), so these are ideal for low-light viewing. Smoothly zoom from 10x to 30x at the flick of a lever. These are excellent for sporting events, birding, nautical applications, and surveillance.
The same big 60mm objectives and BAK4 prisms as our fixed-power 60mm models, including the same highest-quality broadband multi-coatings throughout. All Oberwerk binoculars have rugged rubber-armored metal bodies, all-glass lenses, right ocular diopter adjustment, brass 1/4-20 tripod adapter threading, case, and strap.

NOTE: Fixed-power binoculars offer almost a 50% wider view than zoom binoculars set to the same magnification, therefore we do not recommend zoom binoculars for those primarily interested viewing the night sky (the narrow field of view is an inherent limitation in all zoom optics).
