Ecokra 12x42 HD Binoculars

Ecokra 12x42 HD Binoculars are adult binoculars listed with 12x magnification, 42 mm objective lenses and centre focus. The claimed FMC coating, BAK4 prism and carrying accessories suit outdoor viewing, while the listing’s conflicting prism and mounting details are worth checking if those specifications matter to you.

What to know before buying

Listing details to confirm

The listing is inconsistent about the prism and mounting: the details table says Porro Prism and lists Roof as a mounting type, while promotional text claims BAK4 and the title describes a compact model. It also alternates between 450 Grams and 1 pounds for weight, and between 6.8 Degrees and 374ft/1000yds for field of view. Its waterproof claim is qualified by advice not to leave the binoculars in heavy rain or soak them. Confirm the specifications important to your use before buying.
