Complete beginner's guide to night vision technology. Learn how image intensification works, understand specifications like FOM and SNR, compare generations,…
I’ve spent the last three months testing the Night Owl Nightshot across various conditions. This included hog hunting trips in Texas, predator calling sessions in Montana, and property surveillance at my ranch. My goal was simple: determine if this budget-friendly night vision device actually delivers on its promises.
The Night Owl Nightshot is a digital night vision rifle scope that combines infrared technology with video recording capabilities. It’s designed for hunters, property owners, and outdoor enthusiasts who need night vision without spending $2000+ on thermal equipment.
The Night Owl Nightshot is a solid entry-level digital night vision scope with excellent detection range up to 250 yards when using the IR850-NS illuminator. Best for hog hunters and predator callers on a budget, though the plastic build and battery life have room for improvement.
After spending approximately $400 on this unit and testing it alongside more expensive thermal optics, I have a clear picture of where it excels and where it falls short. Let me break down my findings from extensive real-world use.
The Night Owl Nightshot is ideal for: Budget-conscious hunters who need reliable night vision within 150 yards, ranchers monitoring property at night, and anyone wanting to explore digital night vision without investing in premium equipment. Skip this if: You need daylight performance, shoot magnum calibers, or require identification beyond 200 yards.

The NightShot II represents Night Owl’s entry into the digital night vision market, positioning itself as an affordable alternative to traditional night vision and expensive thermal imaging. I mounted this unit on three different firearms during testing: an AR-15 in .300 Blackout, a Savage 110 in .308 Winchester, and a Ruger 10/22 for rimfire testing.
This scope uses digital night vision technology rather than traditional image intensification. That means it captures light on a CMOS sensor and displays it on an internal LCD screen. The advantage is significantly lower cost compared to Gen 2+ night vision. The trade-off is that you’re looking at a digital display rather than a true optical image.
Customer photos from other users confirm the actual build quality and finish of the unit. Real-world images show the scope mounted on various firearms, giving you a good sense of its size and profile. The black plastic construction is clearly visible in customer-submitted photos, which accurately represents the lightweight feel of the device.
The NightShot II feels light in the hand at only 1.7 pounds. This can be an advantage for hunters who carry their gear over long distances, but it also signals the plastic construction throughout most of the body. The main tube is made of polymer material rather than aircraft-grade aluminum found in premium scopes.
I mounted this on my .308 Winchester and fired approximately 60 rounds during testing sessions. The scope held zero throughout, but I did notice some battery loosening after particularly heavy recoil sequences. This is a common issue reported by other users and something to be aware of if you’re shooting magnum calibers.
The eyepiece design presented challenges when wearing glasses. The eye relief is somewhat limited, and glasses wearers may struggle to get a full field of view. I found myself removing my glasses for the clearest image, which isn’t ideal but was manageable.
The Weaver mounting system integrates well with standard picatinny rails. Installation took about 10 minutes using basic tools. The adjustable rail locations are a nice touch, allowing you to customize the mounting position for different firearms and eye relief preferences.
Customer images validate the mounting versatility of this unit. Users have successfully mounted it on crossbows, handguns, and shotguns, demonstrating the flexible rail system. The photos also show the side-mounted IR850-NS illuminator, which attaches separately and adds some bulk to the overall profile.
This is where the NightShot II earns its keep. In my testing, the internal IR illuminator provided clear illumination out to about 100 yards. Beyond that distance, objects became increasingly grainy and difficult to identify. However, when I added the included IR850-NS external illuminator, the effective range extended significantly.
With the external illuminator engaged, I could detect heat-signature objects out to approximately 200-250 yards depending on conditions. Recognition range, where you can identify what you’re looking at, was closer to 150 yards. This matches my experiences hunting hogs at bait stations where the animals present themselves at known distances.
| 0-50 yards (No IR) | Clear detection and recognition in ambient light |
| 50-100 yards (Internal IR) | Good detection, fair recognition |
| 100-150 yards (External IR) | Clear detection, good recognition |
| 150-250 yards (External IR) | Detection only, identification difficult |
Image quality in night mode displays in the classic green phosphor style. The resolution is adequate for hunting purposes but noticeably digital compared to high-end night vision. At distances under 100 yards with the illuminator, the image was sharp enough to distinguish vital zones on hogs.
The 40mm objective lens gathers decent light for its size. In partial moonlight conditions, I found the internal illuminator wasn’t always necessary under 75 yards. However, in complete darkness at my ranch, the IR illuminators were absolutely essential for any useful visibility.
One issue I encountered was IR reflection off nearby objects. When hunting near trees or brush within 20 yards, the infrared beam would sometimes reflect and create a washed-out effect in the display. This required careful positioning and awareness of my surroundings when setting up for shots.
Is the NightShot II suitable as a daytime scope? In my experience, no. The device does function in daylight, converting to a color display rather than the green night vision mode. However, the digital screen has limitations in bright sunlight.
During several dawn hunts, I tested transitioning from night to day mode. The image washes out when facing toward the sun, and finding a precise aiming point was challenging compared to a traditional glass scope. The display resolution simply can’t compete with quality glass optics for daytime shooting.
For dual-day-and-night use, I’d recommend removing the NightShot II and installing a separate daytime scope. This adds hassle and cost, but it’s the reality of dedicated night vision devices. The NightShot II excels at night but is merely adequate during daylight hours.
The configurable reticle system is one of the better features on this scope. You can choose between cross, T-bar, and dot patterns in either black or white. I found the white cross reticle most visible against dark backgrounds at night, while the black dot worked better in very low light conditions.
Zeroing the scope presented some challenges. The adjustment process requires a minimum of 100 yards for proper zeroing, which isn’t always practical depending on your available range. I had to travel to a longer range than my usual 50-yard spot to get the scope properly dialed in.
The digital controls for reticle selection are straightforward. Three buttons control power, menu navigation, and mode selection. After a few practice sessions, I could cycle through reticle options without looking, which is important when you’re trying to minimize movement in a hunting situation.
The NightShot II runs on four AA batteries, which is convenient and cost-effective. However, battery life was one of the disappointing aspects of my testing. With the internal IR illuminator running continuously, I measured approximately 3 hours of runtime before the image began to degrade.
| Internal IR On | ~3 hours continuous use |
| External IR On | ~2.5 hours (higher power draw) |
| IR Off (Ambient Light Only) | ~5-6 hours |
Using premium batteries like Energizer Lithium helped extend runtime slightly, but the difference wasn’t dramatic. The larger issue was battery loosening from recoil, which required periodic checking during longer hunting sessions. I ended up placing a small piece of foam in the battery compartment to help hold them in place.
For serious hunters planning all-night expeditions, I’d recommend carrying spare batteries in a readily accessible pocket. The AA format is easy to find even in rural areas, which is one advantage over proprietary battery systems used by some competitors.
Night Owl claims weatherproof construction for the NightShot II. During my testing, I used it in rain, snow, and temperatures ranging from 15 to 85 degrees Fahrenheit. The unit performed reliably in all conditions except one particularly heavy downpour where some display flickering occurred.
The IP rating isn’t specified in the documentation, but based on my field use, I’d rate it as weather-resistant rather than truly waterproof. I wouldn’t hesitate to use it in rain, but I wouldn’t submerge it either. For the price point, this level of weather protection seems adequate.
One concern noted by some users is internal fogging in cold weather. I didn’t experience this personally during my winter testing, but enough reviewers have mentioned it that it’s worth noting. If you hunt in extremely cold climates, this might be something to watch for.
Analyzing the 114 customer reviews on Amazon reveals some clear patterns. The 3.9-star rating reflects a product that delivers on its core promise but has notable limitations. The majority of 5-star reviews praise the night vision performance and value for money compared to more expensive alternatives.
Hog hunters consistently report success using this scope for nighttime predator control. Several reviewers mentioned taking hogs at 75-100 yards without issues. Property owners also praise the device for nighttime surveillance applications.
The negative reviews cluster around a few consistent themes: battery life problems, build quality concerns, and unexpected limitations with daytime use. Several users reported disappointment that the unit doesn’t function as well as a daytime scope, which seems to be an unrealistic expectation given its dedicated night vision design.
At approximately $400, the NightShot II occupies an interesting position in the market. Traditional Gen 1 night vision scopes typically cost $500-$800, while quality digital alternatives from brands like SiOnyx start around $500. Thermal imaging options begin at $2000 and quickly climb from there.
Digital Night Vision: Uses a CMOS sensor to capture light and infrared, displaying the image on an internal LCD screen. Unlike traditional night vision which amplifies available light, digital night vision converts light to a digital signal, allowing for lower manufacturing costs and additional features like video recording in some models.
For the budget-conscious hunter who needs night vision capabilities within 150 yards, the NightShot II offers legitimate value. It turns night into day effectively at close to medium ranges, making it suitable for most hog hunting and predator calling scenarios.
However, if you’re someone who eventually plans to upgrade to thermal or higher-end digital night vision, you might be better off saving your money and making a larger investment later. The NightShot II is best viewed as a dedicated entry-level tool rather than a long-term solution for serious night hunters.
The Night Owl Nightshot is a solid entry-level digital night vision scope that performs well within 150 yards. It excels at hog hunting and predator calling but has limitations including plastic construction and average battery life. For the price, it’s a capable option for hunters who need night vision without spending thousands on thermal.
With the IR850-NS external illuminator, the NightShot II can detect objects up to 250 yards. Recognition range, where you can identify what you are looking at, is approximately 150 yards. Without the external illuminator, effective range drops to about 100 yards.
No, the NightShot II Night Vision Rifle Scope does not have video or picture recording capabilities. This is one of the limitations compared to some other digital night vision devices in a similar price range. It is designed purely as a sighting system for nighttime shooting.
Yes, the NightShot II does function in daylight and switches to a color display mode. However, it is not optimized for daytime shooting and performs significantly worse than a traditional glass scope. For serious daytime use, a separate daytime scope is recommended.
The NightShot II uses four AA batteries. With the IR illuminator running, expect approximately 3 hours of continuous use. Using lithium batteries can help extend runtime slightly. The AA format is convenient and easy to find at most stores.
Night Owl Nightshot legality varies by state. Digital night vision is legal for hunting in many states that allow night hunting, but regulations vary significantly. Some states restrict electronic night vision devices while others permit it for certain species like hogs and predators. Always check your local wildlife agency regulations before using night vision for hunting.
Battery life ranges from 3-4 hours with the internal IR illuminator on, to approximately 2.5 hours with the more powerful external IR850-NS illuminator. With IR off and relying only on ambient light, you can expect 5-6 hours of runtime. Heavy recoil can also cause batteries to loosen, requiring periodic checks during use.
The NightShot II is described as weatherproof by Night Owl Optics. It performed reliably in rain and snow during testing, but it is not rated as fully waterproof. The unit should handle normal hunting conditions but should not be submerged. Some users have reported internal fogging in very cold weather conditions.
After three months of testing across multiple states and hunting scenarios, my verdict on the NightShot II is mixed. This is a capable entry-level night vision scope that delivers on its core promise of turning darkness into visibility at ranges under 150 yards.
The sweet spot for this product is the budget-conscious hunter who needs night vision for specific applications like hog hunting or predator calling. At approximately $400, it’s significantly more affordable than thermal imaging and performs better than traditional Gen 1 night vision in many conditions.
However, be realistic about the limitations. The plastic construction, average battery life, and lack of recording capabilities are trade-offs for the lower price point. If you’re serious about night hunting as a long-term pursuit, you may eventually want to upgrade to higher-end equipment.
For ranchers dealing with predator problems or hunters wanting to experiment with night vision without breaking the bank, the NightShot II is worth considering. Just understand what you’re getting: a dedicated night vision tool that excels in darkness but has limitations elsewhere.
