Advantages of Bushnell H2O Binoculars

The Bushnell H2O 10×42 looks good and well made, it feels robust and lyes comfortable in the hand. The rubber coated exterior provides good grip even with wet hands or with gloves. It should also provide adequate protection if the binoculars are dropped accidentally from not too great heights.

The instruments 10x magnification provides images which are detailed and rich in contrast, only near the edge of the lens is a slight drop in performance to notice.  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 view of with 114 m to 1,000 m is within the normal range of binoculars of those specs.

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 with this model.


No many accessories, a carry case only.
