The Bushnell 8x42 H2O Waterproof Black Roof Prism (MPN 158042R) is a mid-size binocular built for people who spend time on or near the water. The 8x magnification paired with a 42mm objective gives a steady, bright image without the shake you get from higher-power glass, and the 305 ft field of view at 1000 yards makes it easy to track moving subjects. Boaters, birdwatchers, hikers, and anyone glassing open terrain in unpredictable weather will get the most out of it. If you're comparing models, it sits in our binoculars lineup as the all-around 8x option.
Bushnell built the H2O around a fully multi-coated all-glass optical system with BaK-4 roof prisms, which holds contrast and resolution better than uncoated or partially coated glass. The housing is O-ring sealed and nitrogen purged, so it carries an IPX7 rating, meaning immersion to one meter for up to 30 minutes without fogging internally. The chassis is aluminum wrapped in a non-slip rubber armor for drop protection and a secure hold with wet hands. Eye relief runs 13mm with a 5mm exit pupil, twist-up eyecups let eyeglass wearers dial in their fit, and a standard 1/4"-20 socket allows tripod mounting. Close focus is 15 ft, and the folding roof prism design keeps the package compact in a pack.
On a boat deck, a duck blind, or a ridgeline, this is the kind of optic you can leave out in the rain and not worry about. The IPX7 sealing and nitrogen purge mean spray, humidity, and temperature swings won't cloud the view, and the rubber armor takes the knocks that come with field use. At 22.7 oz it hangs comfortably on a strap through a long day. Bushnell backs it with a 20-year transferable Ironclad warranty, no receipt required. If you want a smaller pocket model or more reach, check the other H2O sizes in our binoculars selection or browse our night vision options for after dark.
Yes. The H2O carries an IPX7 rating, which means the sealed housing can be submerged in one meter of water for up to 30 minutes without leaking. It is also O-ring sealed and nitrogen purged, so the interior won't fog when temperatures or humidity change.
The 8x magnification brings distant subjects eight times closer, while the 42mm objective gathers enough light for bright images in low light. With a 305 ft field of view at 1000 yards and 15 ft close focus, it handles birding, boating, sporting events, and general glassing across open terrain.
Yes. The H2O includes a standard 1/4"-20 socket, so it threads directly onto a tripod adapter for steady, hands-free viewing during long observation sessions or when using the full 8x magnification over distance.
The 13mm eye relief and twist-up eyecups let glasses wearers retract the cups and position the binocular for a full field of view. The 5mm exit pupil also keeps the image bright and easy to align.
Bushnell backs the H2O with its 20-year Ironclad warranty. It is fully transferable and requires no receipt, covering defects in materials and workmanship for two decades from purchase.
