The resolution and brightness of its 42mm optics are right at home examining the details and colors of distant birds in open field, lake, and shore-side birding. But, unlike many high power binoculars, the Excursion’s close focus is a very good 7’, making this a surprisingly viable choice for close-in birding and butterfly studies. The Excursion is a surprisingly good high power performer across a wide range of observing conditions, bright sunlight and dim twilight alike. This optically and mechanically very good binocular provides performance that was unheard-of at this price point only a few short years ago, and is still rare, even today.

Features of this binocular . . .

• Roof prism optics. H-body roof prism design with internal center focus. BaK-4 prisms for high light transmission. Its 5.6” length is easy to handle, and its light 26 ounce weight won’t weigh you down during all-day birding. A standard ¼”-20 thread tripod adapter socket is built into the body’s front hinge
• Large aperture fully multicoated optics. Large 42mm objective lenses gather substantial amounts of light for bright high power images in twilight or overcast conditions. The twilight factor is 20.49, well above the 17 recommended as a minimum for a low light binocular. The optics are fully multicoated on all air-to-glass surfaces with high transmission antireflection materials for bright, high contrast, natural color response images.
• Phase-coated prisms. The state-of-the-art PC3 phase coatings on the BaK-4 roof prisms were originally designed for the ultra-premium Bausch & Lomb Elite binoculars. The PC3 coatings eliminate the natural phase shift inherent in a roof prism binocular that muddies small details. These coatings give you visibly sharper images and a more accurate color rendition. This is especially noticeable when viewing fine detail or when looking into the rising or setting sun at a silhouetted or backlit bird, where more color is visible in the shadowed areas of the bird.
• Waterproof and fogproof. Dry nitrogen-filled and O-ring sealed to be waterproof and fogproof in all temperature and climate extremes. Designed to operate reliably in rainforests and deserts alike.
• Armor. Black rubber armor absorbs noise and shock. Ribbed gripping surfaces provide a solid hold when wet.
• Twist-up eyecups. A quick quarter-turn counter clockwise twist extends the eyecups for non-eyeglass use. A clockwise twist on the rubber-rimmed eyecups retracts them into the binocular body for eyeglass or sunglass use.
• Long eye relief. Eye relief is specified at 15mm. While this is technically correct, the actual usable eye relief typically measures a mm or two less due to the recessing of the eyepieces when the eyecups are in the down position for eyeglass use. A shorter eye relief than specified is typical of all binoculars. There will be some vignetting of the field for eyeglass wearers.
• Close focusing. One and three-quarter turns of the comfortably-large ribbed focus knob moves smoothly from a 7’ close focus out to the horizon. A 7’ close focus is quite good for a 10x binocular, allowing them to be used for close-in birding as well as long distance viewing.
• Rotary diopter correction. A continuously-variable diopter ring on the right eyecup allows you to match the binocular optics very precisely to your individual eyesight for the sharpest images.
• Supplied accessories. The comfortably wide cloth-covered neoprene neck strap makes the lightweight binocular easy to carry during all-day birding sessions. The neck strap has special clips for quick disconnect from the binocular body. A second set of disconnects are supplied for use with an optional binocular harness to make changing from harness to neck strap fast and easy. The supplied lightweight molded case has a number of unique and useful features. The case has smoothly rounded edges that won’t dig into your body while carrying it. Its interior is divided into two compartments (one for the binocular and the other for a field guide, optics cleaning supplies, or an emergency peanut butter and jelly sandwich). There’s a zippered pocket in the divider that can hold your credit cards or driver’s license. An additional mesh pocket on the side of the divider can hold your car keys. There’s a separate removable woven strap for the carrying case. The tethered objective lens covers flip down out of the way when not protecting the optics. If desired, you can remove the lens covers completely. An eyepiece rainguard completes the supplied accessories.
