Binoculars Price depends upon the brand, quality and size of the Binoculars. Binoculars price start from Rs 100 to even some Lacs also. The price of a binocular depends majorly on the optics used, coatings done on it, Prism type and the brand name. I would recommend somethings not less than 8x40 for a good piece of Binocular. It can be used for bird watching, travelling, sight seeing, and also which everybody forgets for Astronomical Visual Observations.
