The field of view of the binoculars is 137 meters at 1000 metersV. Fairly large lenses provide optimal light output and good color reproduction. Negative aberrations are negligible.
A rather decent weight (850 grams) does not make hand-held observation particularly comfortable, so Bassell 20x50 binoculars have a socket for a tripod L-adapter.
The rubberized housing does a good job of protecting the device from atmospheric precipitation, but it should be borne in mind that the binoculars are not completely sealed and full-fledged water procedures are extremely contraindicated for them.
