PARD Night Stalker 4K eX vs 4K 2.0: which one to choose and why

Two hunters, two devices, one brand and almost the same price. Yet each of them bought something entirely different. The PARD Night Stalker 4K eX and the Night Stalker 4K 2.0 look similar on paper - both have a 4K sensor, a rangefinder and a holdover calculator. The difference between them is so fundamental, though, that the wrong choice will bother you on every evening outing.

This article will save you that disappointment. We will go through what really sets them apart, what it means in the field and who each one is for. No marketing phrases - every figure comes from the manufacturer's official specifications.

The short answer, right up front

Where they came from - the Night Stalker family tree

For the comparison to make sense, you need to know that these are not two generations of the same device. They are two branches of one family.

This is the only explanation for why the „older" eX costs more than the „newer" 2.0. They are not consecutive generations. They are two different views on what night vision should do best.

What they have in common

Before we get into the differences, it is worth knowing that in many respects they are equals. Both models have:

• a true 4K sensor, 3840 × 2160, with 0.001 lux sensitivity
• a laser rangefinder up to 1000 m and a holdover calculator
• a gyroscope, PIP (picture in picture), WiFi, HDMI output and the PardVision2 app
• recoil-activated recording, loop recording and a time stamp
• dual power: a built-in 21700 battery plus a removable 18650
• IP67 protection, operation from -30 to +55 °C and 6000 J recoil resistance
• an aluminium alloy housing and almost identical weight - 896 g (eX) and 905 g (2.0)

In other words: you are not buying a less rugged or less equipped device. You are buying a different compromise.

How digital night vision actually works

Before we get into the differences, it pays to understand what happens inside the device. Without that, the numbers in a table tell you nothing.

A classic day scope is just a set of lenses - light passes through glass straight into your eye. Digital night vision works differently. It is essentially a small camera with a display:

This is the key to the whole comparison. When two manufacturers print „4K" on the box, it only means the sensor captures 4K. It says nothing about how much of that detail reaches your eye.

Difference number one: the display

This is where the two part ways the most - and it is the parameter most easily overlooked in a spec table.

Why this matters more than it seems: the sensor in both devices captures a 4K image, but you only see what the display can show. It is like watching a 4K film on an old television. The sensor captures the detail, the display throws it away.

On the 2.0 the display is an IPS panel at 1280 × 1280. That is solid, and compared to the original model's 800 × 800 it is a visible step up. The eX, however, has a round OLED at 2560 × 2560, which is four times more pixels on the same area.

In practice this means that on the eX you will not see individual pixels even at higher digital zoom, the image feels smooth and the eye does not tire as quickly during long observation. The OLED also gives deeper blacks, which at night is exactly what counts. On top of that the eX offers five colour modes against three on the 2.0.

The hidden difference nobody mentions: pixel size

Both devices have a 3840 × 2160 sensor. But the pixels on them are not the same. The eX has 2.9 μm pixels, the 2.0 has 2.0 μm.

A larger pixel gathers more light. At the same pixel count this means the sensor in the eX is physically larger and starts from a better position in very low light, even though the manufacturer quotes 0.001 lux for both. It is the same principle by which a camera with a larger sensor produces a cleaner image at high ISO than a phone with the same megapixel count.

This is not a difference you will notice on a moonlit night. It is the difference that shows up on the darkest November night under heavy cloud - in other words, exactly when it matters most.

Magnification, field of view and how zoom is controlled

Here the 2.0 wins - but at a cost the advertising does not mention.

Base optical magnification is 5.5× on the eX and 6.5× on the 2.0 (the 70 mm versions). Both devices add up to 4× digital zoom on top, so the full range is 5.5 to 22× on the eX and 6.5 to 26× on the 2.0.

It is important to understand what digital zoom does. Optical magnification comes from glass. Digital zoom only enlarges the pixels you already have. It adds no new detail - it only makes the existing detail bigger. And here the display comes back into play: a device with a finer display tolerates digital zoom far better, because the image does not break into blocks as quickly.

So the 2.0 goes further on paper, but the eX holds a usable image across more of its range.

Zoom is controlled on both by buttons on the body, and the image changes in steps. The 2.0 additionally has a side focus wheel with an assignable function - you can map it to, for example, triggering a range measurement or a holdover calculation, so you do not have to dig through menus. The eX has side focus as well, but without that assignability; in exchange it has larger, grooved buttons designed to be worked with gloves on.

Picture in picture - the feature that solves the zoom problem

Zoom in and you lose the overview. Zoom out and you lose the detail. The PIP feature (picture in picture) sidesteps that conflict - and both devices have it.

In practice this means you can confirm the exact point of impact on a boar without losing sight of the rest of the sounder. With ordinary zoom you would see one animal only, and whatever happened around it would pass you by.

Eye relief - why this number matters in night vision

Eye relief is the distance at which you have to hold your eye from the eyepiece to see the full image. It sounds like a detail, but on rifles with stronger recoil it decides whether the device hits your brow when you fire.

850 or 940 nanometres - the difference that decides whether the game sees you

Both models come with an infrared illuminator in two wavelengths. This is the parameter people get wrong most often when ordering.

The human eye stops perceiving light at roughly 700 nanometres. An 850 nm illuminator sits beyond that line, but not far beyond - which is why a faint reddish glow is visible when looking straight into the objective. A 940 nm illuminator lies much deeper in the infrared and is practically invisible.

The catch is that the same reason you cannot see it applies to the device's sensor as well. Silicon sensors are noticeably less sensitive at 940 nm, so at the same illuminator output, 940 nm reaches a shorter distance and the image is darker than at 850 nm.

Rangefinder: detachable module or hidden in the tube

Both devices measure up to 1000 metres, but they are solved differently - and the difference is visible at first glance.

The Night Stalker 4K eX carries the rangefinder and illuminator in a single detachable module. When you do not need them you take them off and the device is lighter and slimmer. When you head out for a longer shot in the dark, you put them back on. It is a flexible solution, but the module is visible from the outside and changes the profile of the setup.

The Night Stalker 4K 2.0 has the rangefinder built directly into the objective. The manufacturer calls it the first night vision scope with a hidden rangefinder. The setup looks like a classic day scope, nothing protrudes, nothing catches on branches and it sits cleanly on the rifle. In exchange the rangefinder is a permanent part of the device and cannot be removed.

The holdover calculator: what it is really for

The manufacturer calls it a ballistic calculator in the manual. It is a feature many people have in their device and never switch on - a pity, because it solves the most common cause of missing at longer range.

A bullet does not fly straight. From the moment it leaves the barrel, gravity pulls it down. If your rifle is zeroed at 100 metres and you shoot at 250, the bullet will land noticeably lower than where you aim. Exactly how much lower depends on bullet weight, velocity and target distance.

The calculator in the device works out that drop for you and shifts the aiming point in the image so that you aim straight at the target. No guessing „two hands higher", no working through tables in the dark.

How the calculator is set up. In the device menu you enter the data for your cartridge - bullet weight, muzzle velocity, the height of the optical axis above the bore, and the distance your rifle is zeroed at. You will find these figures on the ammunition box or on the ammunition maker's website. You enter them once and the device remembers them.

In the field you simply put the reticle on the animal, press the rangefinder, and the device immediately shows where to aim. The gyroscope adds the angle correction if you are shooting from a high seat or up a slope - and that is exactly the situation where even an experienced shot misjudges by eye.

How many rifles can the device be zeroed to

Both models have five zeroing memory profiles, labelled A to E. That means five different rifles, or five different loads, in a single device.

This is more practical than it sounds. If you have one rifle for boar and another for roe, you do not need two devices and you do not need to re-zero every time you swap. You zero once into profile A, once into profile B, and after that you simply switch in the menu.

The same works with one rifle and two loads - a heavier bullet for boar and a lighter one for fox follow different trajectories, so they deserve their own profiles.

The zeroing procedure is the same on both models: in the menu select Zeroing, choose the profile, fire at a target, then move the reticle onto the point of impact using the X and Y coordinates and save. It is advisable to start at a shorter distance, for example 50 metres, and only then fine-tune at your intended range.

Runtime and power

Both models use the same solution - a built-in 21700 battery supplemented by a removable 18650. The practical benefit is obvious: when the removable one runs out, you slide in a spare and carry on, while the built-in one keeps the device alive in the meantime.

The difference is in total runtime. The manufacturer states a maximum of 8 hours for the eX and a maximum of 6 hours for the 2.0. Two hours sounds like little, but on an all-night wait it is precisely the part of the night when things tend to happen.

The 2.0, on the other hand, has a standby mode - one press puts the device to sleep and wakes it just as quickly, which cuts consumption substantially while idle. If you alternate between observing and waiting, the real difference may not be as large as the catalogue figures suggest.

Full specification comparison

A highlighted cell marks the more favourable value. Figures apply to the 70 mm versions according to the manufacturer's official specifications.

The price gap

The difference between the two models is roughly 90 euros in favour of the 2.0, just under ten percent. That is not the sum that should decide it - with a device that will serve you for years, what matters far more is whether it suits the way you hunt.

For completeness: the range also includes the original Night Stalker 4K with a 50 mm objective and an 800 × 800 display, which is noticeably cheaper. It is still a good device, but the display gap to both newer models is large, so we only recommend it where the budget is genuinely fixed.

Who each one is for

Glossary

If you are new to night optics, here are the terms that recur in this article and on the product pages:

Frequently asked questions

Is the newer 2.0 better than the eX?
Not automatically. The 2.0 is a newer platform with higher magnification and better ergonomics, but the eX has a four times finer display, a wider field of view and longer runtime. They are two different approaches, not two generations.

Will game see the infrared illuminator?
At 940 nm, practically not. At 850 nm it may notice a faint reddish glow, especially if it looks straight into the objective. On most ground this causes no problem, but where game is pressured, 940 nm is worth it.

Do I have to use the illuminator all the time?
No. On a clear moonlit night or near artificial light both devices manage without it. You switch the illuminator on when the darkness is heavy or when you need to reach further.

Can the device be used in daylight too?
Yes, both work in colour mode in daylight. That is one of the advantages of digital night vision over classic image-intensifier tubes, which daylight damages.

How many rifles can one device handle?
Five, thanks to profiles A to E. Each profile remembers its own zero and its own data for the holdover calculation.

Do I need to buy anything else with it?
The box contains mounting rings, a removable battery, a case and a cable. Depending on the rifle, a different mount may be needed - we are happy to advise.

In closing

If you take one thing away from this article, let it be this: in digital night vision it is not the sensor that decides, but the display. Both devices have the same sensor. What you actually see is set by the display - and there the gap between them is fourfold.

If image quality and comfort during long observation are what matter, go for the Night Stalker 4K eX. If reach, a clean silhouette on the rifle and a lower price matter more, go for the Night Stalker 4K 2.0.
