Most bird-watching experts recommend binoculars with 8x magnification. While some birders prefer 10x magnification for more detail, 10x binoculars are heavier and can be harder to hold steady for longer periods of time. Binoculars with 8x magnification also have a wider field of view than those with more magnification, which makes it easier to pick out birds in trees or dense vegetation. Overall, most experts say 8x magnification is a good compromise between magnification and weight.
The Eagle Optics Ranger SRT 8x32 is the second-best pair of binoculars in Birders World magazines test of eight models. It earns a rating of 4.1 out of 5. Testers appreciate the 3-foot close focus, and one tester notes that the binoculars focus quickly and have sharp images.
