Bushnell H2O 10×42 Waterproof binoculars series are just that: completely waterproof and fog proof. They are made for tough outdoor conditions where things can get wet. Water stays out even when taking them on a boat, kayaking, or even in high humidity environments such as rainforests.
The housing is O-ring sealed to keep water out, and its nitrogen-filled insides pure. Being purged with nitrogen means there is no residual moisture inside so there can be no condensation of moisture even when going through extreme temperature fluctuations. The Bushnell H2O Waterproof/Fogproof binoculars are “coated” in a non-slip rubber that can absorb shock while providing safe grip and handling.

Advantages of Bushnell H2O Binoculars
The Bushnell H2O 10×42 looks good, makes a robust impression, feels handy, and is well balanced in the hand.
The rubber-coated exterior provides a 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 10x magnification of the instrument corresponds to a field of view of 102 m at a distance of 1,000 m. This allows distant objects to appear close enough to see detailed, high-contrast images.
The multi-coated objective lens with an aperture of 42 mm in combination with the BAK 4 roof prisms offers good light transmission and sufficient twilight performance so that you can use the binoculars in poor light conditions, such as at dusk or at dawn.
The eyecups are made of soft rubber are rotatable and the focus works flawlessly. The eye relief is 17mm, so most wearers of glasses can use the Bushnell H2O 10×42 without restrictions. Another positive feature is the weight, which is relatively low at 25 ounces/ 709 grams for binoculars of this format.
Bushnell guarantees the binoculars having a hermetically sealed housing. O-ring sealed and nitrogen purged, they are completely waterproof. Even when being submerged, no water can enter and they stay dry on the inside. Fogging and condensation of moisture and mold will be no issue with this model.
Prisms do not have phase-correction coating.
Experts users may notice slight spherical aberration near the edge of the projected images. However, this is normal in budget binoculars.
