The 3x12 Mono T* Monocular from Zeiss is a compact, multi-purpose optic that can be used as a magnification tripler for select models of Zeiss' Conquest, Victory, and Classic series binoculars (adapter sold separately).
The Mono 3x12 T* can transform your Victory FL and Conquest binoculars into a high-performance spotting scope in the blink of an eye by tripling the magnification. A practical alternative to a spotting scope, which pays off on long and varied excursions, such as birdwatching. The device can be securely fixed onto the eyepiece by means of an adaptor ring, opening up a hugely detailed visual experience. The Mono 3x12 T* can also be used on its own as a miniature telescope or as a magnifying glass at close range. The Mono booster is so small that you can easily take it with you wherever you go.
