Prime members save over $50 on these lightweight and powerful binoculars in this early Amazon Prime Day binocular deal. At less than $100, the deal price makes them almost the same price as the 8x42 version that we reviewed last year. They are the same model, but with this pair, you can get 10x closer to the heavens (as opposed to 8x).

The Nikon Prostaff P3 10x42 is on sale now at Amazon for $96.95, their cheapest price since Black Friday.

During our hands-on review last year, we gave the lower magnification version of these binoculars four out of five stars. We thought the design was excellent, and the optics were impressive for binoculars at this price point. We thought they were a top choice for beginners and even included them in our best binoculars guide.

These are a great pair of 'go-anywhere' binoculars that are waterproof and fogproof — great for transitioning between temperatures, such as your warm car, to observing out into the cold. There's also no need to worry if you're caught out in the rain or snow or fret about keeping them dry when you're fishing or sailing. 

They aren't the best choice for stargazing. For that, we'd recommend something like the Celestron Nature DX 12x56. They offer more magnification, let in more light, and are tripod mountable.
