Please help me choose from these binos

AlexG · Guest

Hi,

I want to buy a bino but i need help choosing it. I've read guides and bino things but i lack the hands on practice. Thought i need a expert voice so i've came here. I want to tell me the instability and quality of the image for each magnification rate of these binos since i don't want to use tripod ( rate the brands too please ) :

Tasco Essentials Series :

10x50 , 12x50 , 16x50

Barska :

10x50 , 20x50

PS: Tell me please about the exit pupil ... how much it is best to be 3 mm 5 mm or 7 ?

Hi

Unless you plan to use a tripod, never exceed a 10 for a first binocular number. A 12x, 16x or 20x is too hard to steady without a tripod.

All else equal, an exit pupil of 5 (second binocular number divided by first binocular number) in the 10x50 will offer the brightest image.

For the basics on binocular construction and features is easy to understand terms, see my article at
