Sometimes, you just gotta go birding. Such was my feeling recently when my friend and birding buddy Susan Snetsinger collected me for an all-day birding expedition to Butte and back. As a sizzling pink dawn crept over our neighborhood, I felt particularly excited. Why? Because today, we were going to test two spotting scopes ideal for the traveling birder: the Vortex Viper 11-33X50 and the Vortex Crossfire HD 12-36X50.
Vortex classifies both of these scopes as “Compact” in size, but I also refer to them as “travel scopes” because they are small, light, and fit easily into almost any backpack or suitcase. A few months ago I posted a very positive review of Vortex’s top-of-the line compact scope, titled “Vortex Razor HD 13-39X56 spotting scope with Mountain Pass tripod.” I recommend reading that post again before you read this review as it will help provide the entire story about these three scopes—in descending price order. As you’ll recall, the Vortex Razor HD 13-39X56 runs about $1,000 and is well worth the money. It may be out of reach for many birders, though, and that’s one reason I felt so excited about testing the more affordable Viper and Crossfire compact scopes. The Viper lists at $849.99—but can be purchased for about $600. Meanwhile, the Crossfire lists for $299.99—but can be bought for around $200. “But,” Susan and I both wondered, “how will these two more affordable scopes stack up against each other?”
First, let’s discuss what they have in common:
- Both come in an angled configuration (see image below), which I much prefer to the straight option because it allows for a lower, more stable position on the tripod and easier viewing.
- Both are about 10.3 inches long and weigh in at about thirty ounces—just under two pounds, or a bit more than an average pair of binoculars.
- Both have very similar magnifications, the Viper zooming from 11 to 33X magnification, and the Crossfire 12 to 36X.
- Both are built to fit the Arca-Swiss standard mount, which allows them to be directly fitted to Vortex and many other tripod heads without a pesky adaptor plate.
- Both come with Vortex’s no-questions-asked lifetime warranty, making either scope a worry-free purchase from the get-go.
Which leaves the primary question you’re probably asking yourself: Is the Viper worth the extra $400 I would have to spend over the Crossfire? To begin finding out, Susan and I rolled up to our first stop, Racetrack Pond just south of the town of Deer Lodge. We set up the two scopes side by side, each perched on a Vortex Mountain Pass tripod and began scanning the pond. It was still early in the season for most songbird migrants, but ducks, geese, and swans were out in full force and even as we were setting up, we were delighted to see a flock of 22 Snow Geese flying by. However, we began focusing mainly on Common Goldeneyes, American Wigeon, and Ring-billed Gulls puttering around a tiny island a hundred or so yards offshore.
Controls
As with any new equipment, it took us a few minutes to get familiar with the controls on each of the scopes. Both had eye relief tubes that easily pulled out, and both had about the same zooming range. At first we couldn’t figure out how to easily zoom the Crossfire in and out, but it turns out I hadn’t screwed in the eyepiece tightly enough when assembling the scope out of the box. Once I tightened the “knurled ring” at the base of the tripod, the zooming ring functioned just fine.
The main difference on the controls between the two scopes is the focusing mechanism (see arrows in images below). The lower-priced Crossfire comes with what’s called a helical focus. This is a ring around the entire scope tube that you twist back and forth to focus. The more expensive Viper comes with what is called a dual fine focus—two small knobs conveniently positioned on top of the scope that allow you to quickly adjust them. Spoiler alert: I’m going to just come out and say that, if you can afford it, the dual fine focus alone justifies the extra expense of buying the Viper over the Crossfire. Not only does this system achieve a sharper focus, it is much faster and more convenient to use. I watched a video about this and the host pointed out that this is especially great for digiscoping, or using your phone to take a photo through a scope. I don’t yet do this myself, but it’s good to know.
Optical Quality
One thing I and many others have discovered is that the brightness and clarity of images through optical devices don’t at first seem that different, even between more and less expensive models. That initially seemed to be the case when Susan and I compared the Viper and the Crossfire. The more we used them during our outing, however, the more it became apparent that the Viper gave us superior images. Not only was light transmission better through the Viper, it achieved sharper, clearer focus. That’s not surprising considering that the Viper comes with better coatings on its glass lenses and prisms, but it was still interesting to notice that difference in the field. Later, I tested the two scopes under very low light conditions, and the brightness of the Viper stood out even more.
Build
Both the Viper and Crossfire appear to be very solid and well built. The Vortex website boasts that the Viper features “ultra rugged construction” while it makes no such claims for the Crossfire, so I assume that better manufacturing and materials go into the Viper. However, my guess is that both of these products will perform very well in the field. Both are fog proof and waterproof, essential features for anyone out watching birds. The Viper is purged with argon gas while the Crossfire is purged with the more standard nitrogen. I asked a rep what the difference meant for consumers, and he answered, “the difference isn’t actually with the optical quality, but instead the longevity of the optic. Argon has a larger atom, and will reduce the rate of leakage over long periods of time when compared to nitrogen. Argon is also less affected by sudden temperature shifts and is much more resistant to extreme temperatures.” He also admitted that most users will probably never notice this until at least 10+ years of use—if ever.
Bottom Line
When comparing the Viper and Crossfire head to head, the Viper comes out a clear winner. Both are terrific, lightweight scopes for the traveling birder, but if you can at all afford or save up for the Viper over the Crossfire, I highly recommend it. That doesn’t mean, though, that the Crossfire doesn’t fill an important niche. It’s a great purchase for those on a budget, or those buying a first scope for a beginning birder and, honestly, many people may stay perfectly content with their Crossfires for the foreseeable future. If you need a scope to just carry around in the car or keep in a cabin without having to worry too much about it getting stolen, the Crossfire also could be just what you’re looking for.
Whichever scope you buy, I do highly recommend the Mountain Pass tripod, which is well-suited to both scopes both in weight, dimensions, and cost. I’ll also point out that both scopes work with Vortex’s Pro Car Window Mount. I have not yet used this, but plan to write up a review as soon as Braden and I can head out into Montana’s grasslands this summer.
