The Zeiss Victory 3x12mm Monocular can transform your Victory FL/HT/RF or Conquest binoculars and the Dialyt 8x56 GA T into a high-performance spotting scope by tripling the magnification. In this way, a pair of binoculars with an 8x magnification can be turned into a spotting scope with 24x magnification in the blink of an eye. It can be quickly fixed onto the eyepiece using an adaptor ring. 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.
