Eyepiece 20x WW
The 20xWW is highly suitable for counting birds on large expanses of water or to determine the size of an entire flock. The computer calculated wide angle lens makes a field of view of 54 metres possible and gives you the necessary overview for these tasks. For quick observations in between other tasks the scope can be used without a tripod at a 20x magnification – it’s enough to simply rest the scope on any surface.
