A customer visited the Northern Optics retail outlet at the Waters` edge visitors centre looking for a quality monocular that he could keep in his pocket.
After looking at some smaller 25mm versions, he chose the Visionary M-10 10×50..A major factor was that it needed to fit in a pocket. The M-10 is too large for this, but the customer still chose it due to the case having a belt loop. Meaning he could still keep it on hand when needed..Another factor was the fact it comes with a mini tripod which doubles up as an adhoc pistol grip.
Other main factors were the price, nitrogen waterproofing and excellent optics
From a personal point of view, this monocular with a wide 5mm exit pupil makes it ideal for wide field astronomy as well as bird watching / general use
