The Bushnell H2O 10 × 42 looks good and well made, it feels robust and lays comfortable in the hand. The rubber coated exterior provides good grip despite wet hands or even with gloves. It should also provide adequate protection if the binoculars are dropped accidentally from a low height.
The instruments 10x magnification provides images which are detailed and rich in contrast, only near the edge of the lens is a slight decrease in performance noticed. The objective lens with 42 mm aperture in combination with the BAK 4 multicoated roof prisms, guaranty optimum light transmission and enough twilight performance to allow the binoculars still to be used in low light conditions during dusk or dawn. A field of vision of with 114 m to 1,000 m is within the normal range of binoculars of those specifications.
The eyecups are made of soft rubber are rotatable and the focus works flawlessly. The eye-to-eye distance is 17mm, so wearers of glasses can use the Bushnell H2O 10 × 42 without restrictions. Another positive feature is the weight, which is relatively low at 765 g for binoculars of this format.
Bushnell guarantees the binoculars having a hermetically sealed housing. Special O-rings and a nitrogen filling make the instrument completely waterproof and even being submerged in water would not allow water to enter. Fogging and condensation is supposedly not an issue using this model.
The center focus knob is large so it's easier to adjust, and you also have adjustable twist-up eyecups, giving you as much as 17mm of eye relief, making them perfect for those who wear eyeglasses or sunglasses while hunting.
The prisms used in the H20 use Premium BaK-4 material that offers images with exceptional brightness, sharpness, and clarity. They are then multi-coated in order that you can enjoy the amazing light transmission that ensures brighter images.
The H20 is built to withstand harsh hunting conditions, due to its non-slip rubber armor. This can absorb the shock when you bump into things as you hunt. It also has an extensive textured surface area so you can make sure that you have a secure grip on the binoculars even when it's wet.
This model comes in a 10x42 or an 8x42 option. The 10x magnification makes certain that you can identify your target from further away, while the 42mm objective lens allows lots of light in to keep things bright. At the same time, the binoculars aren't too big that you'll find them unwieldy when you're hunting.
It's also O-ring sealed and nitrogen-purged, and also keeps it completely waterproof and fogproof, which is a major concern for hunters, as we face all type of adverse weather elements.
