Though it is not only the birdwatchers among us that could appreciate the unique ability to see that binoculars of this caliber bring us.  You can look on as a Bald Eagle, in all of its magnificence, dives for a fish in a salt-water lake.

How cool is that? If you are new to the world of binoculars, or if you are considering an upgrade from the binoculars that you now have, you should consider Vortex Diamondback binoculars.

What does 10×42 mean?

As you consider buying a pair of binoculars, your first move is to take steps to understand how binoculars are sized – so, when you read 10 x 42, what information are you being given?

The number 10, in this case, means that the object you are looking that – perhaps that red-tailed hawk – is ten times larger than seen with your naked (or eye-glassed eye).

Now, how about the number 42? This is a little trickier to explain. Binoculars have two lenses; one is further away from your eye than the other is; it is called the objective lens. (The objective lens is not the lens that you look through.)

The number 42 would mean that the second lens is 42 millimeters in diameter. Now, what does the size of the objective lens tell you?

A larger objective lens lets more light into the binoculars. Generally speaking, this means that you can see a clearer image, though it depends on what you are trying to see.

The10x42 size is popular among those who are seriously into watching wildlife, whether as a predator or an observer.

Benefits of Vortex Diamondback binoculars


Until you’ve been out on a ocean-side cliff watching fluffy baby eagles as they lay sleeping in a nest – and the rains come, you cannot fully appreciate how important it is for your binoculars to be sturdily waterproofed. Who wants to pack in it when you are reveling such a visual treat? Not a hiker. Not a photographer. And not a binocular-wearer.

Fog proof

What is the science behind Vortex’s fog proofing feature? Oxygen is purged from the barrels of the binoculars and then replaced with argon gas. Internal fogging of binoculars used to happen when temperatures dropped abruptly; argon gas does not fog up like oxygen in said circumstances. (Oxygen, we love to breathe you in, but we don’t want you fogging up the innards of our binoculars.)Picture of the Vortex Diamondback 10x42 binoculars left side


Do you know what makes rubber such a sought-after material in binoculars and cameras? It is easy to hold on to in any conditions; come rain, snow, sleet or hail. Think about it. We grip on to rubber on our bicycle handles, on our pliers and even on our fancier pens. You really don’t want to drop your binoculars, even if they are as sturdy as those made by Vortex.

Comfortable viewing

Whether you are using your binoculars for bird watching, to track an oncoming winter storm or to help you hunt, you want them to feel comfortable against your eyes. Vortex Diamondback binoculars have adjustable eyepieces, so that you get the fit you need.

Easy focusing

Some binoculars have you focus each barrel individually, you can focus these binoculars with a central tool, meaning less fussing about as that Eastern Coyote wanders into your sight. Or a black bear if you are tramping along a little-worn trail in Maine.

So you see differently from each eye?

If you have better vision in your right eye or vice versa, Vortex binoculars has you covered. You can adjust the binoculars to suit both of your eyes easily.


If you are an amateur photographer you will be wondering if you can use a tripod with Vortex binoculars. You can, though you do have to buy a special adaptor in order to do so. Tripods can remove the risk of binocular shake. What is binocular shake? Holding a binocular with human hands for a long time can result in an unsteady image caused by instability.
