First of all, on the consistency of the model with our needs. For any application where handheld observation is key, do not exceed 10x magnification. For hikers observing mainly in the daytime, compact binoculars with 28, 32-mm lenses are recommended, while for hunters who also use binoculars at dusk, you will need large, 50-, 56-mm lenses. However, the most important thing is to choose binoculars of good quality - here reputable manufacturers come to the rescue: Vortex, Leupold or Delta Optical.
