The focusing is done by turning the waist ring and the gear ratio is relatively high to quickly find the right focus. Zooming traditionally takes place on the eyepiece from a minimum of 9 times magnification up to a maximum of 27 times. The eyecup is a twist type and is turned down if you wear glasses.
The whole tube is coated with an elegant and resistant rubber reinforcement and is filled with nitrogen to protect it to wet weather and other harsh environments.
The spottingscope is delivered with eyepiece and lens caps in rubber and a neat stay-on case.
