Leupold SX-2 & SX-4 Spotting Scopes Explained

Spotting scopes are some of the most useful optics to have on hand. Although they’re often overlooked by the uninitiated, they’re renowned for their ability to provide a clear view of far-off targets. As such, they’re great to have on hand for and long-distance shooting application.

Just like with rifle scopes though, picking just one spotting scope can be a challenge. There are several top-tier options to choose from several industry-leading brands. Among them, however, Leupold spotting scopes are some of the industry’s leading options. More specifically, their SX-2 Alpine HD and SX-4 Pro Guide HD spotting scopes have been widely favored amongst recreational hunters and professional guides.

Leupold: A Brief Look

Before getting into the crux of this article, it’s important to understand the brand behind the optics of today’s discussion.

Leupold & Stevens, better known as just Leupold, has long been one of the optic industry’s leading manufacturers. Originally starting out as a tooling company in 1907, their first foray into the optics scene wasn’t until the 1940s with the introduction of the Plainsmen. It was the first fully water and fog proof rifle scope, and it boosted Leupold’s status within the industry. Ever since, they’ve continued developing top-tier rifle scopes and eventually branched out to create other optics too.

Today, they offer a diverse lineup of rifle and pistol optics, as well as others like binoculars and spotting scopes. Each one is built to Leupold’s exacting standards, ensuring that no matter which one you opt for, you’ll end up with a top-tier optic—a sentiment that extends to their spotting scopes.

Leupold Spotting Scopes

As far as their spotting scopes go, Leupold first started offering them in 1970s and 1980s following the success of their first rifle scopes. By the 1990s, they had a well-rounded lineup of them.

Like we mentioned before, Leupold is still an avid producer of spotting scopes, and they’re often touted as some of the best amongst resolute enthusiasts. That said, of the many they have in their current lineup, their SX-2 and SX-4 spotting scopes are some of the most popular.

Leupold SX-2 Alpine HD

Leupold’s SX-2 Alpine-HD spotting scope is one of the more affordable spotting scopes in their lineup. However, just because they’re more affordable than SX-4 series doesn’t mean that they’re basic.

For starters, like many of their premium rifle scopes, SX-2 Alpine-HD spotting scopes are equipped with Leupold’s High-Definition lenses. With them, they pick up impressive amounts of detail on far-off targets. Plus, they offer excellent light transmission too. For longevity in the field, these scopes are completely waterproof, making them resilient to whatever conditions you may face. Adding to its durability, the optic body is enshrouded in their rubberized Armor Coating, increasing its abrasion resistance and grip. And for better viewing, each SX-2 scope comes standard with a set of form-fit eye cups to block out ambient that could affect your sight picture.

On its own, the SX-2 Alpine-HD is already a solid spotting scope, but Leupold goes a step further to make it even better. As you likely already know, spotting scopes are designed to be used in conjunction with tripods, and the SX-2 is tripod ready out of the box. Attached to the bottom of the scope body is an Arca-Swiss compatible mount. This makes it compatible with several of the industry’s most popular tripod systems. And if you already have a tripod that isn’t Arca-Swiss compatible, it’s threaded to accept other mounting systems too.

Overall, the SX-2 Alpine HD is a solid spotting scope that’s packed to the brim with top-tier features. Currently, these spotting scopes are available in two configurations. You have the choice of either the SX-2 20-60×60 or the SX-2 20-60×80 scope. The core difference between the two is their respective objective lens sizes. Both are great for long-distance spotting, but the larger objective lens of the SX-2 20-60×80 Spotting Scope offers better light transmission and detail, albeit at the cost of size and weight. The 20-60×60 is better for those wanting a slimmer, more portable long-range scope. It still offers a clear picture of your target, and it’s much easier to carry over long distances.

Leupold SX-4 Pro Guide HD

The SX-4 Pro Guide HD builds on the foundation of the SX-2 to deliver even greater clarity and utility. And as the next step up in Leupold’s SX optic line, it brings some serious upgrades.

One of the most noticeable upgrades is this scope’s use of Leupold’s Elite Optical System. With it, it provides excellent light transmission in both bright and low-light conditions. Likewise, it greatly reduces glare while simultaneously maximizing clarity. The SX-4 Pro also houses Leupold’s High-Definition, fully multi-coated lenses. Together, they offer impeccable resolution and image fidelity to give you an extra-clear view of your target. And as if this scope wasn’t already kitted out to the nines, it houses a series of phase coated roof prisms, sharpening its edge-to-edge clarity.

SX-4 Pro spotting scopes don’t just have upgraded glass. Each scope has a rugged optic body that’s built to handle just about anything you, or your environment, can throw at it. Just like the SX-2 series, SX-4 scopes are coated in Leupold’s rubberized Armor Coating for optimal grip and abrasion resistance. On top of this, the lenses are protected with DiamondCoat 2, one of Leupold’s most premium lens coatings. It makes the lenses exceptionally resistant to abrasion, while also providing yet another assist with light transmission.

Finally, the SX-4 Pro series adds some nice quality of life upgrades in the form of a smooth focus system, a built-in sunshade, and an oversized eyepiece. Like the SX-2, they also come with interchangeable eye cups, as well as a bottom-mounted Arca-Swiss compatible mounting point for tripods. Something else to note is that SX-4 scopes have some extra variety too. Notably, they’re available in either a straight or angled configuration. Both types function the exact same way, it’s just that straight scopes have you look directly through the scope from behind, while angled ones have you look through the top like most traditional spotting scopes.

As of right now, Leupold’s SX-4 Pro Guide HD Spotting Scopes are available in either a 15-45×65 or 20-60×85 configuration. Being a more premium choice, these scopes are priced higher at around $1,000 and $1,200, respectively. But regardless of the magnification you opt for, both scopes are offered in either a straight or angled configuration. Plus, if the magnification range is the same, there’s no price difference between the straight or angled scopes. Lastly, like with the SX-2 series, the SX-4 20-60×85 Spotting Scope does offer greater light transmission and clarity thanks to its larger objective lens diameter. However, this also makes it heavier and a bit bulkier. So, for a lighter, more portable scope, the 15-45×65 SX-4 Spotting Scope is the move.

Which One Fits Your Setup

Both the SX-2 and SX-4 spotting scopes from Leupold are incredible, giving you the ability to see far off targets clearer than a standard rifle scope will. And between the two, you can’t go wrong with either one. That said, even though both are awesome, choosing one over the other can still be a challenge. Although the price of each scope will likely be one of, if not, the main factor that determines your choice of scope, there’s more to it than just that.

Outside of your budget, it’s critical to take a good look at your own individual experience and use case. Even though both spotting scopes fundamentally achieve the same goal of getting you a visual on targets that are extremely far off, they go about doing so in different ways. On one hand, you have the affordable SX-2 Series scope. It’s great for enthusiasts of all levels, making it a solid choice for those new hunting or long-range shooting, as well as the seasoned enthusiast. While great, it’s important to note that, comparatively, it lacks many of the features offered by its cousin, the SX-4.

Whereas the SX-2 is a solid entry level spotting scope, the SX-4 just has more to offer, which is fitting considering it’s one of Leupold’s premium spotting scope lines. It’s designed for more serious enthusiasts who need an optic that’s built to handle rough field conditions while keeping a clear view downrange. The edge to edge offered by the SX-4 gives you an exceptionally wide FOV, and its enhanced clarity makes noticing smaller details much easier.

Still, the SX-4 Pro Guide HD can be considered a tad bit overkill for more simplistic use. For example, if you’re planning to hunt in less harsh environments, or just need something to make sighting in your rifle easier, the SX-2 offers more than enough power to get the job done. It’s rugged optic body still makes it a contender for use in adverse conditions too—just keep in mind that it won’t boast the same capabilities as the SX-4

Conclusion

Spotting scopes are some of the versatile optics you can have on hand. They lend themselves well to many different applications, with them being useful for everything from hunting to sighting rifle scopes.

Both the SX-2 Alpine HD and SX-4 Pro Guide HD spotting scopes are some of the top models in the industry. Coming standard with the hallmark durability and lens clarity of Leupold optics, they’re favored by enthusiasts of all experience levels. Still, it’s important to recognize the differences between each optic line.

The SX-2 is a great spotting scope, but if you’re planning to use your scope in harsher field conditions, opting for the SX-4 is the move. Either way, no matter which one you go with, it’ll be backed by Leupold’s lifetime guarantee.
