Frequently Asked Questions - H2O BUSHNELL

How do I adjust the diopter on my Bushnell H2O binoculars?

Cover the right objective lens, focus with center knob using left eye. Then cover left objective lens and rotate the diopter adjustment ring (below right eyecup) until sharp. Avoid forcing.

How should I clean the lenses?

First blow away dust with canned air or soft brush. Use the included microfiber cloth in circular motions. For stubborn dirt, use photographic lens tissue with a drop of isopropyl alcohol (apply to cloth, not lens). Never use window cleaners.

Can I use these binoculars with glasses?

Yes. Turn the eyecups down (twist down) for use with glasses. This provides proper eye relief (17 mm for 8x42 model). For without glasses, twist eyecups up.

What does IPX7 waterproof mean?

The binoculars can be submerged in water up to 1 meter depth for up to 30 minutes. Avoid longer or deeper immersion.

How do I attach the neckstrap?

Thread the strap ends through the strap lugs on each side, then back through the plastic buckle. Adjust length equally on both sides. Use a plastic zip tie if using metal O-rings to avoid scratching.

Can I mount these binoculars on a tripod?

Yes, unscrew the cap on the center hinge to expose a 1/4-20 UNC socket. Use a compatible binocular tripod adapter (e.g., Bushnell #161002CM). Not available on FRP models.

What is the difference between Porro, Roof, and Folding Roof prism designs?

Porro prisms have an offset barrel shape offering wider field of view; Roof prisms are straight and compact; Folding Roof (FRP) are ultra-compact. H2O includes all three types across various SKUs.

How do I adjust interpupillary distance (IPD)?

Hold the binoculars and move the two barrels closer or farther apart until you see a single circular image with no dark shadows. This matches your eye spacing.

What warranty covers these binoculars?

Bushnell Ironclad Lifetime Warranty covers defects in materials and workmanship for the product's lifetime (up to 30 years depending on model). Transferable, no receipt needed. Excludes electronics, batteries, cosmetic damage, misuse.

What are the different SKUs available for H2O?

Common SKUs include 157050R (7x50 Porro), 158042R (8x42 Roof), 138005R (8x25 FRP), 134218R (18x42 Porro), 150142R (10x42 Roof), and others. Refer to the manual for full list.

Thank you for purchasing your new Bushnell® H2O™ binoculars.

This manual will help you optimize your viewing experience by explaining how you can adjust the binocular to your eyes, and how to care for this instrument. Read the instructions carefully before using your binocular.

NEVER LOOK DIRECTLY AT THE SUN WITH YOUR BINOCULAR, AS IT MAY CAUSE SERIOUS DAMAGE TO YOUR EYES

EYECUP ADJUSTMENT

Your Bushnell H2O binocular is fitted with eyecups that provide a comfortable view of the full image and help to exclude extraneous light. If you need to wear glasses when using binoculars, leave the eyecup in the "down" position (Fig. 1, next page). For use without eyeglasses or sunglasses, twist up the eyecups (Fig. 2). This will place your eyes farther from the binocular's ocular lenses, at the correct eye relief distance, allowing you to see the full field of view.

IPD (INTERPUPILLARY DISTANCE) ADJUSTMENT

The spacing between the pupils of your eyes, called "interpupillary distance," varies from person to person. To match your binoculars to your IPD or "eye to eye" width:

1. Point them at a white wall or blank area of the sky. Hold the binoculars and view through them as you normally would. Don't worry about focus yet.

2. Grasp each side of the binocular firmly. Move the left and right sides closer together or farther apart (Fig. 3, next page) until you see a single image with no shaded areas.

FOCUS AND DIOPTER ADJUSTMENT

1. Adjust the eyecups and IPD as described in the previous sections.
2. Using a lens cap or your hand, cover the objective lens on the right side of the binocular.

3. Using the center focus knob, focus on a distant object with fine detail (e.g., brick wall, tree branches, etc) until it appears as sharp as possible when viewed through the left side of the binocular.

4. Uncover the objective lens on the right side, and cover the left objective lens while continuing to view the same object.

5. Rotate the diopter adjustment ring (NOT the center focus knob) located directly below the right eyecup (Fig. 4) to bring the object into focus in the right side of the binocular. Avoid over-turning or forcing the diopter mechanism. If you are unable to bring the object into focus for your right eye by adjusting the diopter ring/eyecup, make sure the left side is still in focus (repeat steps #2-4 if necessary). The diopter adjustment essentially provides "fine focus" on one side of the binocular (right only) to allow for slight differences in the vision of your left and right eyes.

6. Your binocular should now be adjusted for your eyes. Focusing for any distance can now be done simply by turning the center focus knob. Make a note of your diopter setting (position of plus and minus marks on diopter ring relative to index mark on binocular near the ring) for future reference in case the ring is moved accidentally or by another person using your binocular.

NECKSTRAP ATTACHMENT

To attach the neckstrap, thread the ends of the neckstrap through the strap lug (Fig. 5) on each side of the binocular, then back through the plastic buckle on the strap (Fig. 6). Adjust the position of the binoculars on your chest as they hang around your neck to your preference, by changing the length of the strap section which passes through the strap channel and buckle by an equal amount on each side. If you prefer to use an aftermarket strap that has metal O-rings, attach them to a plastic zip tie placed on the strap lugs rather than installing them directly on the lug, to avoid damaging the finish on the binocular via contact with the rings.

TRIPOD MOUNTING

To attach the binocular to a tripod or monopod, unscrew the cap which covers the threaded (1/4-20UNC) socket at the far end of the center hinge (Fig. 7), and set it aside in a safe place. Use a compatible binocular tripod adapter accessory (90° angle bracket), such as the Bushnell #161002CM, to attach your binocular on any standard tripod in a horizontal position, to provide a stable image during prolonged viewing, especially with high power optics. Tripod mounting not available on FRP models.

FULLY MULTI-COATED OPTICS

H2O binoculars have lenses with multiple microthin layers of anti-reflective (AR) coating on every air-to-glass surface. This provides increased light transmission for a brighter, clearer image. It's important to take proper care of your binocular to avoid damage to these lens coatings that could be caused by improper cleaning methods.

CLEANING

1. First, blow or brush away any dust or debris on the lens (using "canned air" or a soft lens brush).
2. To remove dirt or finger prints, clean with the supplied soft storage bag (made of washable micro-fiber cloth), rubbing in a circular motion. Use of a coarse cloth (including paper towels) or unnecessary rubbing may scratch the lens surface and eventually cause permanent damage. The included storage bag/micro-fiber cloth is ideal for the routine cleaning of your optics. Simply breathe lightly on the lens to provide a slight amount of moisture, then gently rub the lens with the micro-fiber cloth.
3. For a more thorough cleaning, photographic lens tissue and photographic lens cleaning fluid or isopropyl alcohol may be used. Always apply the fluid to the cleaning cloth - never directly on the lens.
4. To prevent potential damage to the optical coatings on the binocular's lens surfaces, never use household window cleaning liquids. Avoid using facial tissue or clothing that may have fibers which can be abrasive and hold oils or dirt.

CARE OF THE OPTICS

1. Your Bushnell binocular will provide years of trouble-free service if it receives the normal care you would give any fine optical instrument.
2. Avoid sharp impacts. Set the binocular down gently on hard surfaces.
3. Tug on the strap after attaching, making sure it is securely fastened to the binocular before placing it around your neck.
4. Store your binocular in a cool, dry place whenever possible.
5. All H2O binoculars are tested for water resistance to IPX7 standards. Avoid immersion in water to depths over 1 meter (3 ft 3 in) and/or for periods of time longer than 30 minutes.
