Classic mid-zoom binoculars BPC 10×40 “baigish” , based on a porro prism, Central focusing and diopter adjustment on amateu eyes, made in robust metal housing able to withstand harsh climatic conditions (-40° … +50°C).
Multi-layer coating and high quality manufacture of all optical components provide excellent image quality throughout the field of view.
Limit changes in the Central dioptric setting from -5 to +10 diopters. For people with different visual acuity right and left eye has an additional setting of the right eyepiece. The limit of additional dioptric setting from -3 to +3 diopters.
For determining the distance to the observed object, it is necessary to combine the bottom line of the scale starting with the base image object and the top object on the scale of the grid to determine the distance to the object.
On the right scale is determined by the distance, in metres, to an object with a size of 1.75 meters (a person of average height). On the left scale is determined by the distance, in meters, to object a size of 6 meters (Telegraph pole).
