Apex Covert Pro Review 2026: Illuminated Single-Pin Tested
After three months of rigorous testing, our Apex Covert Pro review reveals real-world performance data, battery life results, and detailed…
The Pulsar Digisight Ultra N450 LRF was one of the most talked-about digital night vision scopes of its era, combining a high-resolution CMOS sensor with an integrated laser rangefinder that promised precise distance readings without any extra gear on the rifle. Hunters loved the all-in-one design, and for several years it set the bar for what a smart digital scope could do after dark.
Then in 2023, Pulsar quietly discontinued the Digisight Ultra N450 LRF along with its non-LRF sibling. New units stopped shipping, factory support shrank, and the scope drifted into that awkward zone where it’s still genuinely capable hardware but no longer a current-production option. That leaves hunters asking the obvious question in 2026: is this discontinued scope still worth chasing on the used market, and what current-production alternatives deserve serious consideration?
This guide walks through what made the N450 LRF so appealing, why Pulsar pulled the plug, and which three digital night vision scopes I recommend instead for hunters who want similar (or better) capability with warranty support and current parts availability. Every pick below is in stock, has verified customer feedback, and addresses a different priority: integrated rangefinding, classic day/night versatility, or extended battery life.
If you’re also shopping for handheld scanning options to pair with a scope, our guide to the best night vision goggles under $500 covers the goggle side of the equation. For dedicated thermal alternatives, see our roundup of best thermal scopes for hunting.
These three scopes cover the most common needs left behind by the discontinued Pulsar Digisight Ultra N450 LRF. Each addresses a different priority, and all three are currently in production with active warranty coverage.
Below is a side-by-side comparison of all three digital night vision scopes that replace the role of the discontinued Pulsar Digisight Ultra N450 LRF. Key specs, sensor details, and battery information are listed to help you pick the right fit.

Magnification: 3-15x
Sensor: Ultra HD 4K+
LRF: Built-in
Battery: 10+ hours
Weight: 2.2 lbs
The ATN X-Sight 5 LRF Ultra HD 4K+ is the closest current-production match to what made the Pulsar Digisight Ultra N450 LRF special: an integrated laser rangefinder, a high-resolution digital sensor, and a smart ballistic calculator that ties distance to holdover in one package. Where the Pulsar was built around a 1280×720 CMOS sensor, the X-Sight 5 steps up to an Ultra HD 4K+ sensor driven by an Obsidian 5 quad-core processor, which means noticeably sharper imagery at magnification and faster menu response.
The built-in laser rangefinder is the headline feature and it directly addresses the same problem the N450 LRF solved. Rather than carrying a handheld range unit or pairing a separate spotter, you get range readings on a single aiming platform. The ballistic calculator then takes that distance, plus humidity, angle, and temperature inputs, and gives you a hold point. For coyote and hog hunters working across uneven ground at night, that kind of integrated workflow is hard to beat.
Field testing confirms the 3-15x magnification range covers the realistic working distances most night hunters actually engage at. The 4K+ sensor holds detail well at the lower end of that range and degrades gracefully as you push toward 15x, where digital zoom inevitably costs some clarity. Recoil Activated Video (RAV) automatically captures footage before and after each shot, and dual stream video lets you record to the SD card while simultaneously streaming to a phone or tablet over Wi-Fi.
Battery life runs roughly 10 hours on a full charge in moderate temperatures, which is a meaningful improvement over the Pulsar N450 LRF’s real-world 4-6 hour window in the same conditions. Cold weather still pulls that number down, but not nearly as steeply as on the older IPS battery system. The Signature Series Power Bundle this unit ships with includes the accessories most hunters need to get started, removing the usual add-on cost creep that often accompanies ATN purchases.
Predator hunters who need integrated rangefinding and want current-generation 4K+ image quality without betting on discontinued hardware. It’s also a strong fit for hog hunters working at variable distances where the ballistic calculator pays for itself on the first bad-angle shot.
The 2.2-pound weight is on the heavier side for an LRF-equipped digital scope, so plan your mount and rifle balance accordingly. The Signature Series bundle sells through a third-party seller rather than ATN direct, so verify warranty transfer terms at purchase.
Review volume is still building since this is a recent release, so long-term reliability data is thinner than what we have on more established models. If you want thousands of verified customer reviews before pulling the trigger, the ATN X-Sight 4K Pro or LTV further down this list will give you that comfort.
Magnification: 5-15x
Sensor: Ultra sensitive NV
Recording: HD video
Battery: Internal long-life
Weight: 1.6 lbs
The ATN X-Sight LTV 5-15x fills the slot the discontinued Pulsar Digisight Ultra N450 (the non-LRF sibling) used to occupy: a classic digital day/night scope without an integrated rangefinder, priced more accessibly than LRF-equipped options, and light enough to mount on most rifles without throwing off balance. It’s the practical choice for hunters who already own a separate rangefinder and don’t want to pay extra for a feature they’ll underuse.
The ultra sensitive night vision sensor handles the full day/night cycle without sensor damage, which is one of the major advantages digital scopes hold over traditional image intensifier tubes. You can leave it mounted and switch from daylight scouting to evening hunting without worrying about burning out a tube or putting on a lens cap. The 5-15x magnification range sits in the practical sweet spot for varmint and predator hunting, where most shots happen between 100 and 300 yards.
HD video recording with sound is built in, which means you can document hunts without adding an external DVR. The 3D gyroscope tracks cant and tilt, useful for long shots on angled terrain where you want to confirm your hold. The internal long-life battery is rated for full-night runtime in moderate conditions, and the 30mm main tube fits standard mounting rings you likely already own.
At 1.6 pounds, this is the lightest scope in the roundup by a meaningful margin. For hunters running lightweight AR platforms or who simply want less weight on the front of a bolt-action rifle, that matters more than it sounds during an all-night sit. The trade-off is no LRF, which is a deliberate design choice: ATN positioned this model as the affordable classic option in their lineup.
Customer-submitted photos show the scope mounted cleanly on a standard 30mm ring setup, with the eyepiece sitting at a comfortable height behind a rifle-mounted flashlight. The compact body profile doesn’t extend far past the objective, which makes it easier to fit inside a rifle case or pack it onto a backpack for spot-and-stalk hunts where you’ll be moving through timber.
Real-world feedback from buyers notes reliable zero retention after recoil and clean day-mode performance for daylight zeroing and range sessions. Some users mention that the included IR illuminator is fine for short-range work under 150 yards but want to upgrade for longer shots, which is the same complaint that came up repeatedly with the older Pulsar N450. Pairing this scope with a quality aftermarket IR light solves that cleanly.
Hunters who already own a handheld rangefinder and want a capable digital day/night scope without paying for LRF they’ll rarely trigger. It also suits anyone running a lightweight rifle where 1.6 pounds versus 2.2 makes the difference between a comfortable carry and a tiring one.
Stock has been tight on this model recently, so if you see it available, it’s worth moving on quickly. The LTV line is also an older generation compared to ATN’s current X-Sight 5 series, so expect lower maximum resolution and fewer smart features than the flagship options.
No ballistic calculator, no integrated rangefinder, no Wi-Fi streaming. Those omissions are by design at this price point, but if you want the smart-scope workflow the Pulsar N450 LRF offered, you’ll need to step up to the X-Sight 5 LRF or the 4K Pro.
Magnification: 5-20x
Sensor: 3864x2218 4K
Battery: 18+ hours
Weight: 2.1 lbs
The ATN X-Sight 4K Pro 5-20x is the most proven scope in this roundup by a wide margin, with 1,798 verified customer reviews and a 4.2-star rating that has held steady across multiple production runs. While the Pulsar Digisight Ultra N450 LRF was still shipping, the X-Sight 4K Pro was already establishing itself as the smart-scope benchmark for hunters who cared more about battery life and sensor resolution than integrated rangefinding.
The 3864×2218 4K sensor driven by the Obsidian 4 dual-core processor produces visibly sharper daylight imagery than anything Pulsar offered in the Digisight Ultra line, and it holds up well into lower night-mode magnifications. At 5-20x you have more zoom range than the typical 4.5-18x Pulsar setup, useful for those long-range predator shots where target ID at distance is the challenge.
The 18+ hour continuous battery runtime is genuinely class-leading. On all-night predator sets where you’re sitting on a call from dusk to dawn, this scope doesn’t need a battery swap. That single spec has shifted expectations across the entire digital NV category and is one of the main reasons current buyers no longer tolerate the 4-6 hour real-world runtime that Pulsar’s older IPS battery system delivered.
The built-in ballistic calculator handles range, wind, angle to target, temperature, and humidity, and it stores multiple weapon profiles so you can switch between rifles and loads without re-zeroing. Recoil Activated Video automatically captures pre- and post-shot footage, and dual stream video records to SD while simultaneously streaming to a paired mobile device over Wi-Fi. The Obsidian 4 processor keeps menu navigation snappy and feature switching responsive.
Where this scope concedes ground is at the top of its magnification range. Pushing past 15x, particularly in low light, brings visible grain and softness that don’t appear in the lower half of the zoom. That’s a sensor limitation common to digital NV at this price tier, but it does mean you’ll want to keep shots inside the 5-15x band for the cleanest image. Some users also report occasional freezing in extreme cold, though it recovers once temperatures stabilize.
Hunters running long nights who need a battery that won’t quit before the hogs or coyotes show up. Also a strong fit for shooters who want the deepest review base and most refined smart features at this price point, rather than chasing the absolute newest hardware.
If your priority is integrated laser rangefinding, this model isn’t it – the ballistic calculator takes manual inputs rather than ranging automatically. You’ll want to step up to the X-Sight 5 LRF for that workflow.
No integrated LRF means one extra step before each shot, which matters on fast targets. Image quality drops at the top end of the magnification range, so plan your engagements accordingly.
Digital night vision scopes work on a fundamentally different principle than traditional image intensifier tubes. A CMOS sensor captures whatever ambient light is available, often paired with a near-infrared illuminator that the human eye can’t see but the sensor detects readily. The sensor then feeds that signal to an internal display – typically an AMOLED panel in current-generation scopes – which you view through the eyepiece. The whole pipeline is software-controlled, which is why digital scopes can offer features like ballistic calculators, video recording, and Wi-Fi streaming that traditional Gen 2 or Gen 3 tubes simply can’t.
Three sensor generations matter for anyone shopping in 2026. First-generation digital sensors delivered usable imagery at close range but struggled past 100 yards. Second-generation sensors bumped resolution to 1280×720 territory (the same chip family the Pulsar N450 LRF used) and added better low-light sensitivity. Third-generation and current Ultra HD 4K+ sensors deliver sharper daylight imagery, better contrast at night, and faster processing, which is why recent models from ATN like the X-Sight 5 LRF produce visibly cleaner pictures than the older Pulsar hardware they’re replacing.
Display technology matters just as much as the sensor. AMOLED displays (used in the Digisight Ultra line and most current ATN scopes) handle black-to-white transitions faster than LCD, which means less smearing when you pan across a dark landscape. LCD panels tend to ghost and lag during fast movement, a problem that becomes obvious when you’re tracking a running coyote. AMOLED also delivers deeper blacks, which translates to better contrast against a dimly lit target.
SumLight is Pulsar’s proprietary low-light sensitivity algorithm, and it’s worth understanding if you’re shopping for any used Pulsar digital scope. It bumps gain and adjusts processing parameters to pull usable detail out of near-dark scenes where a standard sensor would deliver a flat black image. The trade-off is increased noise – the picture gets grainier as SumLight pushes harder. Most hunters find the trade-off worth it for the extra 30 to 60 minutes of useful runtime after sunset and before moonrise.
The biggest source of buyer confusion is the difference between digital night vision and thermal imaging. Digital NV amplifies available light and works in the visible and near-infrared spectrum, which means it produces a picture that looks roughly like a black-and-white photograph of the scene. Thermal imaging detects heat signatures and renders targets as bright shapes against cooler backgrounds regardless of light conditions. They solve different problems: digital NV is better for identifying what you’re looking at, thermal is better for finding warm-blooded animals in the first place. Many serious predator hunters pair a thermal scanner (a handheld unit like the Pulsar Helion or AGM Taipan) with a digital scope like the ones reviewed above, using thermal to locate and stalk, then switching to digital for the final shot identification.
Day-use capability is another major advantage of digital over traditional night vision. Gen 2 and Gen 3 image intensifier tubes can be permanently damaged by exposure to bright daylight or even direct sunlight, which is why traditional NV scopes ship with elaborate lens caps and warning labels. Digital sensors don’t have that vulnerability. You can leave a digital scope mounted on a rifle, walk into a sunny field to confirm zero, and then move directly into a dark tree line for evening hunting without swapping optics. That single feature has driven a lot of the shift toward digital in the consumer market.
Choosing a digital night vision scope after the Pulsar Digisight Ultra N450 LRF was discontinued means balancing the features that made the N450 special against the realities of buying current-production hardware. The decision framework below covers the criteria that actually matter in the field, not the spec-sheet numbers that look impressive but rarely affect hunt outcomes.
The Pulsar N450 LRF pioneered the integrated rangefinder workflow for digital scopes. One button press, distance appears on screen, ballistic data follows automatically. If that’s the workflow you want, the closest current match is the ATN X-Sight 5 LRF Ultra HD 4K+, which pairs a 1000m laser rangefinder with a full ballistic calculator in a single package. If you already carry a handheld rangefinder and don’t mind the extra step, the X-Sight 4K Pro or LTV let you input distance manually to the ballistic calculator and save several hundred dollars.
Pulsar claimed 8 hours for the N450 LRF, but real-world testing consistently shows 4-6 hours with normal IR usage, dropping to 2-3 hours in freezing temperatures. Any current scope you consider should be evaluated on real-world runtime, not marketing claims. The ATN X-Sight 4K Pro’s 18+ hour rating is the current benchmark and is the most honest number in the category – it actually delivers that runtime in the field. The X-Sight 5 LRF sits around 10 hours in practice, which is more than adequate for all-night hunting with a battery swap or USB power bank backup.
Stock IR illuminators on both the Pulsar Digisight line and the ATN X-Sight LTV top out around 150-175 yards for reliable target identification. Beyond that distance you’ll see a bright blob rather than identifiable features. The standard upgrade path is an aftermarket 850nm or 940nm IR light from manufacturers like Sniper Hog, N8Vision, IR Light Builds, or Infinity IR. Mounting an external IR off the scope’s 30mm tube or a side rail preserves the scope’s built-in IR for close-range scanning while delivering 300+ yard illumination when you need it.
Recoil ratings above 5000 joules cover everything from rimfire up to .300 Win Mag and similar magnums, which is the safe zone for any modern digital scope. The Pulsar N450 LRF was rated to 6000 joules, comfortably handling magnum recoil. The ATN X-Sight 5 LRF, LTV, and 4K Pro all sit in the same recoil-safe range. Where things get tricky is mounting on bolt-action rifles, where the scope body style and eyepiece height can interfere with bolt handle clearance. Test-fit before you commit, especially on shorter-action bolt guns where the scope sits close to the receiver.
This is the decisive factor for anyone still considering a used Pulsar Digisight Ultra N450 LRF. Pulsar stopped producing the unit in 2023 and parts availability for repairs has steadily shrunk since. Firmware updates for the N450 line ended years ago, so any bugs or quirks in the current software are permanent. Current-production ATN scopes ship with active firmware support, full warranties, and a steady replacement parts pipeline. For a tool you depend on for hunting, warranty support matters more than a few hundred dollars saved on a used unit.
Forum feedback from serious predator hunters is nearly unanimous: a digital scope alone is incomplete. A handheld thermal scanner (Pulsar Helion 2, AGM Taipan, or similar) lets you locate warm-blooded targets at hundreds of yards before you ever raise the rifle. Then you switch to the digital scope for the final identification and shot. This pairing costs more upfront but dramatically increases your effective success rate, especially in heavy cover where coyotes and hogs can hide from even a good digital sensor.
If you’re committed to finding a used Pulsar Digisight Ultra N450 LRF anyway, set a firm price ceiling around $1,500 and inspect the IPS7 battery carefully – aged Li-ion cells that have sat unused lose capacity and may need replacement, and replacements are getting harder to source. Verify the rangefinder laser returns accurate readings on known targets before paying. Check the sensor for any white spots, bright pixels, or image-sticking issues that indicate a failing CMOS chip. Bring a rifle and confirm zero retention after a magazine of fire. Any seller unwilling to let you test the unit on a known-distance target should be avoided.
Pulsar discontinued the Digisight Ultra N450 LRF in 2023 along with its non-LRF sibling. New units stopped shipping to retailers, and factory firmware support has since wound down. Used units remain available through specialty retailers and private sellers but without active warranty coverage.
Only at a steep discount and only with careful inspection. The integrated laser rangefinder and 1280×720 sensor still perform well at typical predator-hunting distances, but the discontinued status means no warranty support, aging IPS7 batteries, and no firmware updates. For most hunters, the ATN X-Sight 5 LRF Ultra HD 4K+ delivers similar rangefinding capability with current warranty and parts availability.
The ATN X-Sight 5 LRF Ultra HD 4K+ is the closest direct replacement, offering an integrated laser rangefinder, ballistic calculator, and Ultra HD 4K+ sensor in one unit. For hunters willing to input distance manually to a ballistic calculator, the ATN X-Sight 4K Pro 5-20x offers sharper 4K resolution and 18+ hour battery life at a similar price.
The Digex N450 is Pulsar’s current successor in the Digex line, moving from the older Digisight body style to a standard 30mm main tube for easier mounting. It uses the newer APS2/APS3 battery system with better cold-weather performance than the N450 LRF’s aging IPS7 packs. Image quality and the integrated rangefinder concept are similar, but the Digex line is what Pulsar currently supports.
Pulsar rated the detection range at 550 meters under ideal conditions, though reliable target identification requires closer distances. With the stock 850nm IR illuminator, identification is realistic out to about 150-175 yards. Adding an aftermarket IR illuminator like the Sniper Hog LRX 66 extends useful identification range to 300+ yards.
Yes, with some caveats. The Digisight body style is wider than a traditional riflescope and the eyepiece sits higher than most scopes, which can interfere with bolt handle clearance on shorter-action rifles. Test-fit before committing, especially on compact bolt-action platforms. The newer Digex line with its standard 30mm tube addressed many of these mounting complaints.
The Pulsar Digisight Ultra N450 LRF earned its reputation honestly: integrated laser rangefinder, solid sensor, smart software, and the kind of build quality that made it worth the original asking price. Its 2023 discontinuation doesn’t erase that, but it does change the buying math. A used N450 LRF at a steep discount remains a capable scope for hunters who already know the platform, but for anyone buying fresh in 2026, the ATN X-Sight 5 LRF Ultra HD 4K+ delivers the same core rangefinding workflow with current-generation sensor quality and full warranty support.
If your hunting style doesn’t depend on an integrated rangefinder, the ATN X-Sight 4K Pro 5-20x remains the smart pick. The 18+ hour battery, proven 4K sensor, and 1,798-review track record make it the safest buy in this category, and it pairs beautifully with a handheld thermal scanner for finding game before you ever shoulder the rifle. For hunters who want a lighter, simpler digital scope without smart features, the ATN X-Sight LTV 5-15x covers the classic day/night use case at the lowest weight and price in this roundup.
The honest verdict: the N450 LRF was an excellent scope for its time, and a used example in good condition can still get the job done. But in 2026, current-production ATN alternatives give you better sensors, longer battery life, and active warranty support at competitive prices. For most hunters, that’s the better trade. If you do pursue a used Pulsar Digisight Ultra N450 LRF, inspect the battery, verify the rangefinder on known targets, and confirm zero retention before paying.
