Bushnell Permafocus 10x50
The Bushnell Permafocus 10x50 binoculars belong to the Bushnell Permafocus series. The unique part of this viewer is the patented focus-free system; you no longer need to focus! The moments when the bird flew because focusing took too long are gone forever! Win those precious seconds and turn them into unforgettable watching moments!
Purposes
The Permafocus viewers are designed to immediately show objects at longer distances in a sharp and crisp display. The focus on short distance is individual, depending on the sharpness of your eyes. Ideal in situations where the focus can jump from one moment to the next, think of sports and spotting animals. The 50mm lenses catch a lot of light and this makes the Bushnell Permafocus 10x50 excellent for use at dusk as well. Tenfold magnification so even at the last row in the stadium you'll have a crispy sharp image.

Powerful binoculars, that's for sure. Also, the autofocus functionality is just great: no longer do you need to focus manually.
I mainly use these binoculars for birding and astronomy.
