Whales got smart when they were being hunted aggressively many years ago, and they learned to stay away from boats and people. If you are one of the many people who love to watch them play, you’ll want a good pair of binoculars to bring them closer to you so you can see them in detail.20
There’s a wide variety of binoculars available today, and it may be puzzling to know where to start looking for that perfect pair. We have reviewed many and compiled a list of six that we think you may enjoy. Of course, we want you to get the full picture of each, so we’ve listed some of the pros and cons of each one for you to read.
|Best Overall||Nikon Action 7×50||
|Best Value||Wingspan Spectator 8×32||
|Bushnell H2O 10×42||
The Nikon 7239 Action 7×50 EX Extreme All-Terrain Binocular has 7×50 magnification and an exit pupil of 7.14. The objective lenses are multi-coated to allow the most light to come through the Porro prisms. The eye relief is long, and they have turn-and-slide eyecups to make them comfortable for people who wear glasses to use. These binoculars also have a large central focusing knob that’s easy to use, and a diopter control to focus each barrel individually.
The Nikon 7239 binoculars are made with a rugged rubber-coated body that will give you a good grip, so they don’t slip out of your hands. They’re also made to be waterproof and fogproof.
50 is a pretty good-sized optic lens, and that makes these binoculars heavy to carry around. It’s even more difficult because there’s no strap on the carrying case. Another issue with these binoculars is that the lens caps are really flimsy and are not tethered to the binoculars at all, so they’re easy to lose.
All in all, we think that these are the best whale-watching binoculars of 2020.
The Athlon Optics Midas ED Roof Prism UHD Binoculars have 8×42 magnification and extra-low dispersion objective lenses with a 5.25 exit pupil. The lenses have advanced fully multi-coated dielectric coating that reflects over 99% of the light that comes through the binoculars. The extra-low dispersion lenses, combined with the ESP dielectric coating, give you bright and accurate colors. They have long eye relief, making them more comfortable to use, and are argon purged to provide them with better thermal stability and excellent waterproofing.
We did find a few issues with these binoculars. The close-range focus is under three meters. That minimizes the amount of area you can see at one time without moving the binoculars.
The central focus knob is stiff, and it makes strange noises when you turn it. It sounds like the movement of something stuck that you just oiled and are breaking free.
You also need to be careful with the rubber lens caps. They fall out easily and leave your lenses unprotected.
The Wingspan Optics Spectator 8×32 Compact Binoculars have eight times magnification, an 8.00 exit pupil, and 32mm objective lenses, and offer a wide field of view. They’re compact and lightweight, making them easy to carry with you. They also have a lifetime warranty. If anything gets damaged, Wingspan will replace your binoculars. That doesn’t happen too often, though, because they have a non-slip grip on them to help keep them firmly in your hands.
These binoculars are easy to transport but challenging to focus, especially when you’re using the smaller objective lens. It doesn’t allow a ton of light to come in, so your images appear dark.
These binoculars also fog up easily if they get any dampness inside them. That’s bad because the lens covers are tough to get on, so you tend to set them down carefully, without putting the covers on, until you’re ready to put them away. If there’s dew or light rain, they will fog up easily from the dampness.
The Bushnell H2O Waterproof Roof Prism 10×42 Binocular features ten times magnification powers, 42 mm objective lenses, a 4.2 exit pupil, and a 102-foot field of view. It has a rubber coating for a non-slip grip, and it’s waterproof. Bushnell offers a lifetime warranty for any damage that may occur to these binoculars.
These Bushnell binoculars are difficult to use because they’re very hard to focus and give you dark and blurry images. They’re particularly hard to see with because there are no eyecups to block out the outside light around you.
These binoculars are heavy to carry around and awkward to hold. They also fog up easily.
The Sightron SIIBL832 8×32 Binocular set offers 8×32 magnification with a 4.00 exit pupil. These binoculars have a phase corrected prism and fully multi-coated objective lenses to give you the best images possible. They are waterproof and fogproof to make them easier to see through, and have twist-up eyecups to make them comfortable on your eyes.
The images you get with these binoculars are not great. The coloring isn’t very vibrant, and they appear pretty dark. The focuser is stiff in cool temperatures, and the strap and lens caps are made poorly. The poor quality on the strap makes it uncomfortable to wear these for very long.
The Celestron SkyMaster 20×80 Binoculars have a 4.00 exit pupil. They have multi-coated optics to allow in the most light possible. They also have long eye relief, as well as a rugged rubber coating for your comfort.
These binoculars are not collimated, and are tough to get focused. It seems that no matter what you do, you always have double images. They don’t want to merge together as one, and if they do, you’d better not move because the slightest movement blurs the field of vision.
The neck strap on these binoculars is poorly manufactured and is actually painful to wear with the heavy weight of these viewers.
Binoculars are identified by a set of numbers, such as 10×42. This tells you the magnification of the lens and the diameter of the objective lens.
The larger the objective lens and magnification powers are, the more the binoculars will weigh. The heavier weights can be difficult to hold still for long periods, so larger sets of binoculars can be attached to a tripod to make your viewing more comfortable.
These binoculars generally have a thumbwheel you can turn to change the magnification without changing your grip on the binoculars. These are identified by showing a range, such as 10-30×60. This means the lowest magnification is ten times, and you can adjust them to be up to 30 times closer.
Zoom binoculars are more versatile, but keep in mind that the prisms in all binoculars are made for one specific power. As you move away from that number, your image may lose some of its crispness.
The exit pupil number tells you how bright the object you’re viewing will appear when you’re in lower-light places. It’s calculated by dividing the objective diameter by the magnification number.
Example: Using our model from above, if you have 10×42 binoculars, you would divide 42 by 10, giving you an exit pupil diameter of 4.2mm.
For low-light situations:
Models with a higher exit pupil number (5mm or higher) are recommended.
For daylight viewing:
The human pupil can narrow to roughly 2mm to block out light. All binoculars have exit pupils that are either that size or larger, so the exit pupil size isn’t as important.
The eye relief is the distance between your eyes and each eyepiece while you’re viewing your object. Longer eye relief allows you to hold the binoculars farther away from your face and makes them more comfortable to use.
Tip: The eye relief number is beneficial for those who wear glasses. If you do have glasses, we recommend binoculars with an eye relief of 11mm or more.
Field of View:
The field of view tells you how wide an area (in feet) you can see from 1,000 yards from where you’re standing. The field of view usually gets narrower with higher magnification numbers.
● Central adjustment wheel: This wheel adjusts the focus of both viewing barrels at the same time.
● Diopter adjustment ring: The wheel is usually located on one of the barrels near the eyepiece. It focuses each barrel individually.
All binoculars have prisms inside that adjust the view so that you see it as it is. Without prisms, the objects you’re viewing would appear upside down because of the way light moves through the binoculars.
1. Porro: Porro prisms are usually less expensive than roof prisms, but they’re more cumbersome.
2. Roof: These binoculars tend to be slimmer and smaller than those with Porro prisms. They’re an excellent choice for those who love the outdoors. You can usually see a little more detail, so they tend to be a bit more expensive. You can read more about the differences here.
As light hits the prisms in the binoculars, some of the light coming in gets reflected out, making objects look darker than they really are. The lens coating helps deter the amount of reflection to allow as much light through as possible.
Waterproof and Weather-Resistant:
● Waterproof: These typically have O-rings to seal the lenses and help prevent moisture, dust, or other small debris from getting in.
● Weather-resistant: These are made to protect against light rain, but not full submersion in water. They are not totally waterproof.
There’s nothing more annoying than your binoculars fogging up with different temperatures, as your warm breath in the cold air. It isn’t always just irritating, though. Fogging can also cause condensation to get trapped inside.
To protect against fogging of the internal lenses, companies have begun to use inert gas with no moisture content inside the optical barrels instead of air. The gas won’t cause condensation. This protection is only on the internal lenses, not the external ones too.
