Binocular rangefinders work on the principle of shooting laser on the target and using it to measure the distance between you and the target. But there is more to it. With developing technologies, rangefinders, in general, have come a long way. Compared to the latest rangefinders, the older versions are nowhere near as accurate. It currently comes with a lot of features which makes the purpose of target range measuring much easier. So now you have a better understanding of what a rangefinder binocular is, let us get into the things you have to consider.

The internal range finder is coupled with a compass for easier operation, which will help you to quickly establish your bearings and find distances. And not only are these binoculars waterproof, but they will actually float if dropped into water. The latter is a useful feature, particularly on boats. Thanks to Barska's incredible attention to detail with superior optics and waterproofing technology, the Deep Sea Waterproof Floating Binoculars are a no-brainer when shopping for range finding binoculars. They offer amazing features at a great price, and you will be able to enjoy this high-quality product for a long time.
Measuring only 5 ½ inches long, this new Nikon delivers a lot of optical horsepower in a compact and lightweight package. And what an elegant package it is. The Monarch HG has a number of stylistic features that reminded us of the last premium Nikon binocular: the EDG. There’s the pebbled-­rubber armor, the finely turned eyecups, and the Euro-style metal objective lens rings. The Monarch delivers an image on par with the premium furnishings. The “field-­flattener” lenses widen the field of view and reduce peripheral distortion.
The low-cost Pentax AD 8 x 25 WP are ideal for day hikes or airplane travel, where you want good-quality optics in a small package. Everything worked—the eyecups felt solid and comfortable, the hinges weren’t too loose, and focusing was quick and surprisingly accurate at any distance. Of course, this is not the pair for serious birding, stargazing, or anything requiring exceptional detail. But if you want inexpensive, very compact binoculars, this is the pair for you.

At a magnification around 7x to 10x, position yourself so that you can hold the binoculars firmly in place while viewing. Binoculars with overly high magnification may cause unstable image and uncomfortable viewing due to shaking by hand movement. When using high-magnification binoculars, you can fix the binoculars in place using a tripod to steady your field of vision for extended viewing without any worries.
The only weak points of the Monarch 5 are the field of view and close focus range, both of which are slightly on the wrong side average. The 330 foot at 1000 yards field of view is relatively narrow, but we honestly didn't notice that narrowness except when doing side-by-side comparisons with models that offer wider fields of view. The close focus range of 7.8 feet is also slightly long, meaning you'll have to backpedal a bit if you come across a cool bug and want to take a look at it with your bins. If you want a wider field of view or closer focus range the Vortex Diamondback 8x42 is a worthy replacement, but overall we think the Nikon Monarch 5 is the best pair of bins you'll find at this price point.
Whilst both telescopes and astro binoculars are designed to give you a better view of the heavens at night, they both have their unique advantages and disadvantages and thus the best option will vary depending on your requirements at that moment. It is because of this, most people that a very interested in astronomy and practice it a lot, will posses at least one telescope AND a pair of bins.
Seeing as all of the major manufacturers of optics have a pair or two of laser rangefinder binoculars, it’s no surprise that Nikon wants to be in that game as well. The LaserForce 10×42 is among their best offerings, but what really makes it stand out is the 1900 yards distance however, that number should be taken with a grain of salt. Even Nikon themselves mention that the number was achieved under their measurement conditions, and you might not be able to achieve the same in less-than-ideal conditions. Aside from that, its features and specifications are more or less on par with other premium offerings from that price range. Let’s take a better look at the specs.
Hopefully you found the information included above to be useful. You can use all of the information to streamline your decision-making process as to whether or not you want to purchase rangefinder binoculars, and also use it to better educate yourself about this technology – as well as others. They are definitely incredible tools, but may or may not be useful in your specific circumstance or situation.
Telescopes are big. Even little ones are bigger, heavier and longer than most binoculars. So telescopes need to sit on tripods or rocker-boxes for stability. A hand-held spyglass might have been good enough for Captain Kidd, but every modern navy uses binoculars. Angling a long tube up toward the sky makes the shake problem even worse; your extended arm wiggles the front objective lens. Binoculars can lock in tightly to both your eye sockets and your hands are close in to your face for more stability. [Related: Best Telescopes for Beginner: A Buying Guide]
