I have an X-Sight 5 and my ZULUS HD V2 5-20X outperforms the X-Sight in every aspect at a significantly lower price point. I have the Zulus on my compact air rilfe. It’s weight and size make it a perfect combo for hunting.
It’s pretty rare to find a product that doesn’t leave you wanting for more. The Thermnite does everything it claims and does it well. The user interface is intuitive. The image quality is great. I’m 100% satisfied.
Great scope! Mounted on a Tenpoint TRX 515 Crossbow. Setup was straight forward relatively easy. Zeroing was a smooth process, ballistics setup relatively easy, had a small issue with the android phone app got through that fairly quickly and now I need to put a lot more shots through it and charge confidently into hunting season. Very much worth the investment!
Great thermal scope! Blown away by the quality ! Using the scope as a standalone thermal optic for finding coons my dog trees, but it has such good picture quality I will use it for predator hunting also.
I had just received the gun to mount the zulus to but have been getting familiar with all the functions and the digital picture is quite bright and night vision is excellent IMHO. So far so good will do another review once I take them both to the range.
Since the release of the ZULUS HD V2 series, the ZHD520R-V2 has generated significant buzz in the industry thanks to its refined design and upgraded features. Now that the first round of reviews are in, let’s h ear what professional hunters and outdoor enthusiasts have to say about this digital day and night vision scope.
"Blown away by the clarity of this scope!"
When purchasing a night vision scope, image quality is obviously one of the most important factors to consider. So, how does the ZHD520R-V2 perform in real-world applications?
@Top Shot Dustin, a seasoned shooting and hunting YouTuber known for his in-depth gear reviews and real-world tests, shared his firsthand experience, “I just wanted you to look through the optic. Everything’s super bright, even in the shadows. If there were a deer or hog on the lane to the right, I wouldn’t be able to see a thing. But through the DNT, it looks just fine.”
@On the Chase Outdoors is a YouTuber focused on outdoor adventures and hunting. He took the ZHD520R-V2 on a hog hunting trip and highly praised it, saying, “This optic will get you out into the pitch black. You can go full predator mode on pigs, coyotes, rats, foxes—whatever you need to hunt, this optic will get it done.”
In addition to the influencers, regular users share similar sentiments.
John Ross Rinacke noted, “Daytime image quality is excellent... Even at 20x zoom, image quality remains solid. There's slight pixelation, sure, but nothing that affects performance. The night vision is impressive... Out in the country, the IR illuminator really shines—literally. I could see out to around 500-600 yards with no issue.”
Jarrod Copeland was "blown away" by the scope's clarity and said, “The auto IR mode is a game changer! NO MORE GLARE!! The stock IR light is plenty capable, and I don't see the need for an additional IR source.”
"The Ballistic Calculator is amazing."
Beyond its clarity, the ZHD520R-V2 also excels in rangefinding and long-distance shooting.
John Ross Rinacke praised the scope, saying, “The built-in ballistics calculator is incredibly accurate. It matches the mil adjustments I get from both the Hornady and Applied Ballistics apps.”
Michael Shackelford, who already owned a ZULUS V1 non-LRF model, decided to upgrade to the V2 for the rangefinder and ballistic calculator. After testing it, he was impressed and exclaimed, “Wow. I have 28 optics as of now, including thermals, and I must say, price doesn't prevent performance. One of my favorites.”
Martin Lee Andrada, who is in the military and uses white phosphorus night vision goggles all the time, was initially skeptical about digital night vision scopes. However, after trying the ZHD520R-V2, his first digital night vision scope, he happily commented, “I can honestly say how impressed I was with the quality of the night vision! Especially considering they are priced around $700. Another feature I love is the LRF and the ballistic calculator. I zeroed my rifle in three shots and was able to group shots at 50 yards with no problem. It is a game-changer!”
With its integrated laser rangefinder and ballistic calculator, the ZHD520R-V2 ensures precise long-range shooting with remarkable accuracy.
"One-step zeroing is a total game-changer."
Just as Martin Lee Andrada mentioned, the one-shot zeroing feature stands out.
John Ross Rinacke, a previous Arken SH4J user, was looking for a scope that could handle both long-range plinking and nighttime varmint hunting. That's what led him to ZHD520R-V2. He shared, “There's now a freeze-screen function that makes zeroing easier... One-step zeroing is a total game-changer. I zeroed at 50 and 100 yards, then went straight to 300 yards and easily shot a 5-round group on a 4” target.”
William Durnal added, “The freeze frame zeroing function and intuitive controls make this scope all that my *** (a famous brand) should have been.”
This feature is especially useful for hunters who require quick, reliable adjustments in the field, ensuring they are always ready for their next shot.
"More manual and just natural."
After listening to user feedback from the ZULUS HD V1 series, we aimed to provide more intuitive control in the V2. This resulted in noticeable changes in the ZHD520R-V2's design. John Ross Rinacke noted, “The zoom wheel was replaced with a throw lever, which is a nice touch.”
@On the Chase Outdoors also praised the change, saying, “They've changed the zoom feature from a little scroll wheel. They've upgraded to a traditional zoom style with a little knob. It's a lot easier to find at night. It's a lot easier to manipulate and know what you're doing. It feels a little more manual and just natural.”
Additionally, @Top Shot Dustin echoed similar thoughts, saying, “It's genius because it's just like a traditional scope.”
This design makes zoom adjustments much easier, even when wearing gloves or in low-light conditions.
"The interface is much more intuitive."
Beyond its appearance, the ZULUS HD V2 series has also undergone internal upgrades. Taking inspiration from DNT Optics' flagship ThermNight series, the ZULUS HD V2 series now offers a much smoother and more convenient interface, making it easy to master with little instruction.
Jarrod Copeland remarked, "Features are great and navigation is simple."
@On the Chase Outdoors highlighted, "Another thing I really like is they've upgraded the display and the buttons. It's the same as the ThermNight now. The features on the screen are just incredible."
John Ross Rinacke commented, “With the updates in the V2, this optic is a major improvement over what I saw in videos of the V1. The interface is much more intuitive.”

Eye Relief Comparison Between Arken Optics EP5 and DNT Optics TheOne
When comparing the Arken Optics EP5 7-35×56 Gen 2 and the DNT Optics TheOne 7-35×56, one of the key specifications to consider is eye relief, as it directly impacts the shooter's comfort and safety, particularly with high-recoil rifles. Both scopes share identical eye relief measurements, offering 3.5 inches of eye relief.
When zooming into the target, the eye relief did decrease slightly with both scopes but remained very usable.
Why Eye Relief Matters
Eye relief is the distance from the eyepiece of the scope to the shooter's eye where the full field of view remains visible. For long-range shooting, where precision and comfort are paramount, adequate eye relief is essential. It ensures that the shooter can maintain a consistent cheek weld while still seeing the entire field of view, even under recoil. A 3.5-inch eye relief is considered standard for high-performance scopes designed for long-range applications, as it accommodates a wide range of rifle calibers, including heavy-recoil options like .300 Win Mag or even .50 BMG.
Detailed Comparison of Eye Relief
Both the Arken Optics EP5 and DNT Optics TheOne are specified with a 3.5-inch eye relief, which was confirmed through official product pages and supporting documentation. This measurement is consistent across their magnification range of 7-35x, ensuring that shooters can maintain a clear sight picture without adjusting their head position, even at high magnification.
Arken Optics EP5 7-35×56 Gen 2: The official product page (Arken Optics USA) lists the eye relief as 3.5 inches, aligning with the article outline and user discussions on forums like Snipers Hide and Reddit.
DNT Optics TheOne 7-35×56: Similarly, the DNT Optics Store (DNT Optics Store) and other retailers like myhighpressureair.com confirm a 3.5-inch eye relief, matching the Arken EP5 exactly. This shared specification reflects their common manufacturing origin, as both scopes are produced in the same facility with similar design principles.
Implications for Shooters
The identical eye relief of 3.5 inches between the two scopes offers several advantages:
Consistency: Shooters who own or switch between these scopes can expect a familiar shooting experience without needing to adjust their cheek weld or head position. This is particularly beneficial for competitive shooters or hunters who may use multiple setups.
Versatility: The 3.5-inch eye relief is suitable for a wide range of rifle types and calibers, making both scopes versatile for competitive shooting, hunting, or tactical use. It provides enough distance to prevent scope eye (brow strike) even with heavy-recoil cartridges, enhancing safety.
Safety and Comfort: With high-recoil rifles, a longer eye relief reduces the risk of injury from the scope striking the shooter's brow during firing. The 3.5-inch distance provides a safe and comfortable shooting experience, even under demanding conditions, such as extended range sessions or adverse weather.

Welcome! We at DNT Optics love to share our knowledge and our experiences in hopes they may help you. When it comes to seeing in the dark, many think that higher resolution is critical, but that is not always the case. In fact, you can be successful even with lower resolution systems. In the world of thermal, some people dismiss the entry level systems like 256 thermal devices. But we want you to know they can work and work well.
Yes, 256 thermal can absolutely work, but it is dependent on the activity you are pursuing. When hunting, think of how we normally hunt in the day time. We typically scan an area with our eyeballs first. Once our eye detects something of interest, we augment our natural vision with a tool that has magnification, like binoculars. If we see the game that we are pursuing, we then transition to our weapon and use our primary aiming device.
Higher resolution thermals can produce a nicer image, but there are other factors beyond pure resolution. Base magnification is something to take into account. If you compare 1x thermal devices like 640, 384, and 256, you'll see that at a certain point, there are diminishing returns. You can only see so far with said devices even if you spend more money. However, thermal excels at showing you a difference in temperature and since it does not rely on light like night vision, it can be used in absolute darkness. Thermals are very good at detecting heat, but being able to recognize, let alone positively identify, the object you are looking at requires you to get physically closer or use magnification (optical, not digital).
Remember, thermal devices are tools, and like other tools, they have their uses. A 256 resolution thermal can have its use in your tool box. A small 1x thermal scanner is easier to scan with at night than pointing your gun and moving it around all night just to look for potential game. 256 thermal monoculars are more affordable and they can help you scan an area to detect potential game quickly. Scan a field, see anything living? No? Now you can plan your next move. On the other hand, if a 256 thermal scanner shows you something of interest, then you need to decide what your next move is. Move closer or wait for it to come closer? Or deploy a higher magnification thermal or higher resolution thermal.
Our Hydra series of thermal scopes have an AI algorithm that we call Super Resolution. When you turn it on, the image is sharpened. For the entry level Hydra HS225, it enhances the image at any magnification, making a 256 sensor thermal image as clear as a 384 sensor. Higher resolution models like the HS325 or HS635 further benefit from Super Resolution when digitally zooming in. With Super Resolution, a 384 sensor can deliver clarity comparable to a 576. A 640 sensor can reach an impressive 960 at its 6x magnification. Depending on the size and distance of the object you are looking at, the Super Resolution might help you see it more clearly. This can help inform you on your next move. Do you continue to pursue or move on to another target?
Lower resolution thermals are not a substitute for higher resolution devices but they have their uses. They are usually more affordable and when utilized properly, they can absolutely help you on your hunt.

It all started with a crunch.
While walking through quiet Marco Island, John Johnson heard something unsettling. Following the sound, he found a large green iguana devouring an owl egg. As the frantic owl parents screeched, John knew exactly what he was looking at—an invasive species.
Green iguanas aren't native to Florida. Since arriving in the 1960s via the pet trade and accidental escapes, they've thrived. With lifespans of up to 20 years, females capable of laying as many as 71 eggs a year, and no natural predators, their population has exploded.
The result? Widespread damage. Reaching up to 5.6 feet in length and weighing over 15 pounds, iguanas dig deep burrows that undermine sidewalks and seawalls. Their climbing habits lead to roof damage and power outages. On top of that, they carry Salmonella, posing health risks to people and pets.
Over the years, Florida's iguana problem has grown from a mere concern to a full-fledged crisis. Seeing the destruction firsthand, John knew it was time to act. As a lifelong hunter who started out with a BB gun as a kid in the Pacific Northwest, John had the experience and passion to take on the iguanas.
In 2023, he founded Down Goes Iguana, a company dedicated to removing these invasive creatures from Marco Island's shores. That year, he removed 253 iguanas. By 2024, the number soared to 730, with 56% of them being females. This means John prevented over 20,450 iguanas from hatching, as each female can lay about 50 eggs annually.
As a registered Florida State Wildlife Control Officer, John carries out humane, regulated, and highly precise iguana removals. His mission is to protect Florida's native species and restore the balance of nature. And he's not alone in this fight.
When DNT first learned about John, it wasn't just his impressive numbers that stood out, but his precision, principle, and purpose. He embodies the values our gear was designed for. So, we decided to support his efforts by equipping him with the ZULUS HD 5x20 LRF scope, a versatile digital day-and-night vision device built for real-world performance.
For John, the ZULUS HD quickly became essential. Mounted on his Brocock Atomic Carbine air rifle, it gave him the clarity and confidence for precise shots, even in challenging conditions. As he puts it, "The lightweight ZULUS is a game-changer when I have to hand-hold."
Beyond portability, the ZULUS packs a range of features. John says, "It records video of everything you see in the scope and if you put on your best Marlin Perkins voice, you can record the exact moment live as it happens. It is great for some reticle screen grabs like you see here. This scope also features an in-scope rangefinder and infrared for night vision hunting."
By the end of June 2025, John had removed 620 iguanas in just six months—hundreds more than the same time the previous year.
Accuracy is critical for John, whose typical shooting range is between 15 and 50 yards. He explains, "Accuracy is also improtant for iguanas. Body shots rarely stop them, even head shots are often absorbed and they keep going. You pretty much must hit a dime spot in order to bring them down with a single shot." Iguanas are expert hiders. When perched in trees, finding them is only half the battle. Branches deflect pellets, and their tough, scaly skin makes them hard to kill. If the first shot misses, the iguana usually escapes into the brush, water, or worse—into a burrow to breed again.
Thanks to the ZULUS HD's exceptional clarity, John captures every detail, ensuring each shot is as accurate as possible. The built-in rangefinder offers real-time distance feedback, allowing for precise drop compensation. John also loves the video recording feature, which helps him review his shots to refine his technique, document his hunts, or ensure he complies with state guidelines.
Still, one of the biggest challenges remains locating iguanas in dense foliage. Recently, the DNT ThermNight caught John's attention. With advanced thermal imaging, it could help him spot iguanas more effectively in dense foliage or low-light conditions, whether in trees or on the ground. It could be the tool he needs to track these elusive creatures more efficiently.
John's mission is far from over—and neither is ours. As he strives to keep Florida's ecosystem in check, DNT is right there with the right gear.
Unlock your potential with the ZULUS HD and ThermNight series.
When the Hydra thermal scope launched with its 3-in-1 design, many were skeptical. Could one thermal imaging device really deliver handheld, standalone, and clip-on performance without breaking the bank? Turns out, it can. But don't just take our word for it. Hear what real users have to say.
Handheld Mode: Clear Views, Easy Portability
Many users appreciate the Hydra scopes' portability and clarity. Jerry Mitchell shares his satisfaction with HS635, "Purchased this to use as a handheld to pair with my ZULUS LRF. Makes for a great combo and I don't have to be on my gun all evening. The clarity and functionality is really fantastic."
Likewise, Derek Tipple highlights HS635's compactness: "Mostly as a handheld monocular, it's worked great. It's lightweight and compact without the mount... I've observed deer out to 900 yards… Clarity is as advertised."
The HS325 model also stands out for handheld use. Ezra Miller notes, "By far the best entry level thermal I've ever tried out. Does phenomenal in all three roles of handheld, clip-on, and standalone scope!" L.M. adds, "I use my HS325 as a spotter for hunting coyotes. Works great and has excellent clarity. Using the Hydra as a spotter and the ZULUS to shoot is a deadly combination."
HS225 users also appreciate its handheld convenience. Rolyn Smith praises, "Fits in my hand great for using it as a handheld." Jon Janica adds, "Much better than I expected, excellent clarity. Bought this to use as a spotting device... Has better clarity than my thermal that cost $3000.00."
Standalone Scope: Effortless Precision, Exceptional Value
Mounted on rifles as standalone scopes, Hydra devices continue to impress. After trying HS635 in the field, Brian Heard recommends, "Excellent performance and an outstanding value considering the price point. Note I have not used it in clip-on mode, only as a handheld spotter and a thermal scope. Zeroing was literally a one shot process."
For those comparing Hydra to its competitors, Spencer Beal states, "My basic HS635 package had everything needed to get up and running and mounted on my 6.8 SPC. The last optic I purchased five years ago was for $5,000. The HS635 is leaps and bounds better for 1/2 the price."
The HS325 model also shines in standalone mode. Kyle Whisker remarks, "I'm very impressed at the value and versatility. I have it sighted in as an optic for one rifle and as a clip-on for another. It's also very handy to use as a scanner. Image quality is impressive for 384."
Marcus Harrison, an HS225 user, shares the same feeling, saying, "This is a great optic as a standalone and paired with my ZULUS 3-12. I could not be more happy with it."
Clip-On Mode: Smooth Mounting, Seamless Performance
One of Hydra's biggest strengths is its ability to convert into a clip-on, without adding weight or disrupting zero.
Regarding HS635, J.L. appreciates the mode-switching convenience. He comments, "...Most importantly was the option for me to use it as a clip-on (my preferred use)... The fact you can save different "zeros" for different set ups is excellent, and they understand the difference between zero for a clip-on and zero for use as a scope, this is extremely important!"
HS325 also excels in clip-on mode. Brady Nunn compliments, "Really great optic, pairs extremely well with my LPVO set up… smooth transition between color schemes, easy to set up and run on the app…" Veteran user TEM also praises its military-level quality and versatility, saying, "I've used thermals for the last 30 years and the Hydra HS325 is comparable in quality to the military thermals but multi-functional. I'm currently using it in the forward position of my optics. Clear and concise picture. Great thermal."
HS225 proves just as capable in clip-on mode. Mikel Estes finds it useful for hunting, saying, "Scope works well. Easy to zero and use as a clip-on addition for my LPVO while hog hunting."
Real-World Ready: Unleash the Power of Hydra 3-in-1
All these prove that the Hydra 3-in-1 concept is not hype, but truly works. From hunters to military veterans, users value Hydra's clear, sharp imaging and effortless portability, combined with reliable accuracy and quick, easy mounting. Its versatile design fits handheld, standalone, and clip-on roles perfectly, delivering dependable performance and convenience in any situation.
