How far can I see with these binoculars is a question we get often asked; here’s our explanation on why it doesn’t actually make sense.
Allow me to explain why. A binocular’s main goal is to magnify whatever you’re looking at, such as the moon, which is approximately 240,000 miles away. If you want to see even further than that, you can look at the sun which is 93 million miles away (not recommended unless you want to burn out the retina in your eyes!). So, it’s not a question of how far can binoculars see, but how much you want to magnify the object you’re seeking to bring closer.
What Does Magnification Mean?
Magnification is how much larger an object appears when viewed through a binocular compared to how large the same object would appear when viewed with the naked eye from the same distance.
For example, if you are trying to decide between an 8x vs 10x binocular, a deer will appear ten times larger through the 10x binocular than with your normal eyesight. Or eight times larger with the 8x and so on. This allows hunters to more closely observe big game and see details like body and antler size more clearly from a greater distance, without the animal even knowing you’re watching.
Let’s simplify it even more. You’re standing at the edge of a 100-yard clearing. You’re looking at a tree line at the opposite end of the clearing. With a 10 power binocular, the trees will appear as if you’re only 10 yards versus what the tree line would look like with your unaided eye. Basically teleporting you 90 yards closer for a more detailed look.
Determining the Magnification of My Binocular
The first number printed on the binocular represents the magnification. For example, in this case a 10×42 6.5 the magnification would be 10x, allowing you see 10 times your normal vision. The “X” refers to how many “times” the binocular magnifies your view. A 10X binocular magnifies 10 times.
Best Binocular Magnification for Hunting
Binocular magnifications range from 8-15 magnification or even higher, but powers from 8-12 are generally preferred for hunting. There are pros and cons to both higher and lower magnifications. Hunters should choose magnification based on what best meets their specific type of hunting and eyesight needs.
8x Magnification: In most cases, an 8 power binoculars will provide a wider field of view, larger exit pupil, and longer eye relief than a 10x or higher binocular. The 8x binocular is a great choice when hunting in thicker timber or high brush areas. Also when you need the maximum light gathering capability. You’ll also notice if you use your binoculars for a length of time, low powered binoculars like an 8x or lower provide a steadier image vs a 10x or higher. Faint shaking from the hands or wind will also seem greater with larger magnification binoculars.
10x & 12x Magnification: Binoculars with 10 or 12 power do an excellent job of bringing your subject very close and providing the extra detail the lower powered binoculars cannot. Hunters who hunt in wide open fields, mountain ridges or large lakes, will appreciate the stronger power to see their prey at greater distances.
15x Magnification: Binoculars with 15 power magnification are best suited mounted on a tripod and in some cases, replace the need for a spotting scope. The increase in magnification and overall size, makes it difficult to hand-hold, but once rock steady, can provide incredible detail at long range.
Most hunters make the mistake of assuming that in all cases and for all uses, 12x or higher binoculars are better than those with lesser powers. However, the most powerful binoculars are not always the best option. Sometimes it is better to hold back a bit as there are many other important factors to consider when choosing the best long range hunting binocular for your specific needs.
How Far Can I See With These Binoculars?
Bigger is not always better. Bigger magnification results in improving detail at greater distances. But, that’s at the expense of more sensitivity to hand shake and less field of view. Plus, because the exit pupil is usually smaller in a 10×42 vs. 8×42, the image will not be as bright during low light conditions. And while the image you see will be larger with higher powered binoculars, your field of view will narrow, and consequently, unless well practiced, you’ll find it more challenging to keep the image steady. Again, it depends on your needs, conditions and preferences.
