TFB Review: Pulsar Trail 2 LRF XP50 Thermal Imaging Riflescope

This review will cover the European version of the Pulsar Trail 2 LRF XP50.

The U.S. version will have a shorter eye piece, which won’t have the wide angle.

The Thermion XP50 and the Trail 2 have the same <40 mK sensor, magnification and displays. The image quality should be similar, but the Trail 2 LRF has a built-in Laser Range Finder and comes with a mount.

Below: A rare sight together – Pulsar Trail 2 LRF XP50, Accolade 2 LRF XP50 and Axion XM30S. All with their purpose.


The new Pulsar Trail 2 LRF XP50 is made out of black polymer with a long rubber eyepiece to black out any incoming light as you’re looking at a screen. All the buttons are covered by black rubber, apart from the start/shut off button which is Pulsar blue. There is a lens cap on a hinge, which is great as you always have it.

Below: Switching the battery is easy. This is one of the few contacts the electronics have to the outside world.

One the left side (looking downrange) there is a Laser Range Finder (LRF) module. This is easy to use, and quite convenient as it’s more difficult to estimate the distance to your target with a thermal sight.
When you use the LRF the image zooms out to 2.5x automatically for an overview.

Trail 2 LRF comes with an IPX7 waterproof rating, to protect the unit from water and other foreign particles. According to Pulsar, the unit is designed to run flawlessly, even after submersion in up to 3 feet of water for up to 30 minutes. While the temptation to test this is strong, we haven’t.

Image Quality

Image quality, perhaps the most important feature of any optic and certainly a thermal imaging device like this. The two main components that deliver the image is of course the sensor itself and the small screen that delivers what the sensor sees.

The sensor is an uncooled 640×480 @ 17 µm, NETD <40 mK sensor. NETD (Noise Equivalent of Temperature Difference) is one of the most important parameters for any thermal detector, and describes their sensitivity. NETD is typically being expressed in millikelvins (mK). The value is measured in a laboratory with ideal conditions. The lower the NETD value, the higher the sensor sensitivity.

The micro display is an HD AMOLED in resolution 1024×768, and it’s great. To compare, the Accolade 2 LRF binoculars have a 640×480 display and the difference is noticeable for sure. Don’t get me wrong, the Accolade 2 is great, but the Trail 2 is better.

The refresh rate is 50 Hz, which is important when shooting at moving targets. Low refresh rates are the main reason why I haven’t bought my own thermal device, but Trail 2 LRF is excellent and delivers a fluid motion that doesn’t lag. Even if you do a quick scan over a large sector, you will discover areas of interest (heat), so you can stop and look closer. Is it a hot rock or an animal?

The magnification is from 2 up to 16 (x8 zoom), but I used only 2-3 magnification most of the time.

On a perfect sunny day you may not be able to see the difference between an old device and a brand new one so easily, but in the morning after the rainy night when everything has more or less the same temperature, there will be a noticeable difference.

Before I mounted the Trail 2 to a firearm, I used it as a monocular just to be able to walk around and evaluate the performance without having my suburban neighbors calling the police. There is quite a lot of wildlife going on in suburban parks and small forests as the sun goes down!

Still image. Don’t say that thermal imaging can’t display depth. Most of the time I used the Observation Mode, but there are other settings for wood, rocks or your custom setting.

I was able to stand from between 8-40 meters from a roe deer. When I returned the night after, I spotted two kids with it, an unforgettable experience only available through night vision.

Below: This is what they look like when you accidentally use the flash on your smartphone.

If your target is relatively close, say 50 meters, and you adjust the focus, so you get it just right, it feels like there’s a depth in the picture. The resolution, both in terms of the minimal temperature changes it can detect and the screen quality, is really good. If you like this effect, I think it was enhanced when using Red hot but it could be subjective.

Once you get used to this kind of image quality, it’s hard to go back. As technology develops, I know I will regret typing this, but I don’t see a huge need for anything better.


The Picture-in-picture is a setting in the software and displays a magnified image at the top-center 10% of the overall field of view for a closer view of the target or a more precise shot placement.

The testing platform

I used my bolt-action Ruger Precision Rifle Gen 1, in caliber .308 Win. The ammunition is GGG loaded with 168 gr Sierra Match King bullets. With a traditional 12x optic, this firearm is tried out from 300 meters (5 shots within 8 cm) to 45×45 cm steel at 900 meters. The handguard has been upgraded to one from Catalyst Arms and the Trigger was changed to a flat one from Timney, both an improvement over the original parts.

I used a bipod and a support bag at the rear, all shots fired sitting from a concrete bench. I would certainly have shot more stable and better from prone as I’m used to.

As you have noticed in the pictures, the Trail 2 has also been fitted to a JP Enterprises PCS-12 semi-automatic AR10 clone, in 6.5 Creedmoor. I never shot with this setup, but it should work just fine.

For a short while, it was also mounted to a Stormtrooper CTR-02 AR15.

Range Time! Zeroing and grouping at 100 and 300 meters.

I have never zeroed a Pulsar or any other digital scope before. I am the type of person that doesn’t read the manual until I really have to (and then it’s usually to no help anyway).

I stapled a hand warmer onto an IPSC paper target at 100 meters and sent one round, aiming at the hot spot. My spotter said it was high, so I aimed for the bottom of the paper and got a hit on the paper. Based on this hit, I froze the picture and told the sight where I aimed versus where I hit.

The Trail 2 then recalibrated and I shot again, this time with a hit on the hand warmer. I considered this my first hit in a 5-shot group. The group was approximately 3.5 cm (1,4″) which I consider good enough for hunting, but we all have our own standards.

Below: Handwarmer made a very small signature on a hot summer day, but I was still able to zero and shot a nice 5-shot group (red hot).

I could have been done and gone home for the day, but there were some targets at 300 meters, with electronic marking. I don’t want to destroy any sensors or cables on those targets, so after some calculations, I decided to find an aiming spot that hopefully would get me hits around the center of the target.

Below: Through the reticle picture, and not recorded with the internal device.

I went for 12 power magnification on the Pulsar Trail 2. Remember that these paper targets are far from ideal for a thermal sight, so it’s not easy to find a steady spot or reference to aim for.
You’re looking at a digital display, and if you increase the magnification it feels that you just increase the pixelization and haze.

My first round was sent at the 300-meter target and was amazed when I noticed that I hit the center 10 (10.4)! The purpose of this exercise was not really to hit the center, but rather to see what kind of groups I could shoot. I shot another 4 rounds without looking at the result. In the end, the result was a 5 shot group within 117 mm or 4.6″ (<12 cm)!

I know that the rifle and ammunition are fairly accurate together, and my best group with a normal optic is around 8 cm. Not much different from the group I just shot with the Pulsar.

I still find it hard to digest and comprehend that I managed to shoot and hit at this level, having spent just a total of 12 rounds! I was expecting to spend a lot more effort and ammunition. I guess that is proof that the Pulsar sight is accurate and easy to use.

Customizable Reticle Options

Inside the menus, there’s a wide array of color-customizable reticles, including scalable ballistic styles. There’s a catalogue that shows all the reticles here.

Video Time

Below you can see a variety of videos recorded with the Pulsar Trail 2. These are recorded with the built-in photo and video recorder, which is extremely easy to use. There’s 16 GB of internal memory for you, which means a huge amount of hours of recorded video.

Pulsar’s Stream Vision

When it comes to the software, it works fine but I did have some problems connecting the device to my iPad. I think the main problem was not related to the app, but that the iPad had a preference to switch over to my much stronger WiFi network at home. I did not use Pulsar’s Stream Vision a lot, mainly because I downloaded all my recorded videos and pictures at home via cable.


The Pulsar Trail 2 LRF XP50 is a high-end thermal sight, there’s no doubt about it. At no instance during my review did I think that the system’s performance was too low. I didn’t experience any lag or similar issues, and I didn’t discover any bugs in the software. If you have an animal (or heat source) within 40-50 meters the image quality and resolution are amazing, but the scope can detect up to 1800 meters (1.1 miles).

For years I have been looking to get into night vision, but the devices I looked at were either too bad or too expensive. The Trail 2 isn’t cheap, but for what you get I wouldn’t call it expensive. It cost a lot of money, yes, but if you’re an avid hunter, it’s still affordable and the resale values seem to hold well.

This device has really made me appreciate Mother Nature more and got me closer to wild animals than ever before. It’s hard to explain in text, but if you use it right, you can really discover things that you would never ever experience without it. It’s obviously a sight, to be used for hunting, but you don’t have to shoot anything to have a use for it.

I wish for a more tactile feel in the buttons. Now it can be a little difficult to know if you pressed the button or not.

Any battery-powered device is going to need a recharge sooner or later, but in none of my excursions did I have any problems with the battery life. If you’re going away for a few days, on a long hunt, then you need to start planning ahead and conserve the energy.

Switching and charging batteries is really easy, just make sure you store the charger and the cable where you can find them.

The Picatinny mount seems like it could be of better quality, but I couldn’t really find any errors with it and there are up to 4 screws that hold it together.

An auto-focus would have been nice, but I think that would make the unit much more expensive and fragile with moving parts in the lens.

Below: 12 meters or 13 yards. How close can you get? Note the picture-in-picture. Cold summer, around midnight. (Black hot)
