The saving is great, but you get more than just a powerful and reliable pair of binoculars. You also get a range of accessories, useful ones too. It also comes with a tripod adaptor (using a tripod is useful for shake-free views and preventing tiredness in your hands and arms) and a carry case. Both are handy as these binoculars are sizable.
A 25x magnification and 100mm aperture means lots of light passes through the lenses and you can zoom in to see distant objects comfortably. It's also made with BaK-4 prisms and rubber armor for quality views and durability. You can check out our guide for binoculars deals for other top discounts.
Key Specs: Here, the magnification and power stand out. It's a 25x magnification, making really far-off objects visible and the 100mm objective lens diameter means lots of light passes through. A rubber armor means these binoculars are durable, water resistant and comfortable. Bak-4 prisms mean you get quality optics too.
Accessories: A carry case and tripod adaptor are the stand-outs. Both are well needed as these binoculars are sizable and it makes transporting and viewing a lot easier.
Buy if: You're looking for a pair of binoculars for stargazing or long-distance Earthly viewing. These are also well suited to those with more experience using binoculars.
Don't Buy if: You're completely new to using binoculars or you're only wanting a pair for bird-watching or viewing at short-to-medium distances. Also if you're budget doesn't quite stretch this far, there are other models that don't quite offer the power but do come in at a lower price point.
Alternative models: If this isn't quite right for you, we would recommend the Celestron SkyMaster Pro 15x70 binoculars. We think they're the best on the market for views of the moon, they're powerful and they come in at a much lower price point.
