The foam pack provides a snug and supportive fit for all Helion Thermal monoculars.

Quick-Disconnect Lens

All Helion XP models feature a quick-disconnect style lens system that allows the user to change the native optical magnification, field of view, and detection range in seconds. Simply press the disconnect button, twist, and pull the lens housing away from the main body of the Helion. The QD lens system even retains manual focus adjustments and IPX7 waterproofing rating!

8 Color Palettes
The Helion features multiple color pallets for varying environmental conditions and user preference. In addition to black hot and white hot the Helion has Red Hot, Red Monochrome, Rainbow, Ultramarine, Violet, and Sepia.

Picture-in-Picture mode
Picture-in-picture gives you the benefits of a wide field of view and a narrow field of view at the same time with a zoomed-in and a zoomed-out image simultaneously displayed in the sight picture. This type of innovative image enhancement has never been offered on a thermal monocular before the Pulsar Helion. The PIP window covers 1/10 of the display to the field of view remains virtually unobstructed for simultaneous PiP and full FOV viewing.

Built-in video recording
Capturing still images and video is a one-button task with the Helions’s built-in video recorder and image capture. Image and video content is stored on internal memory and can be wirelessly transferred to a smartphone, or transferred to a PC via USB cable..

Note: Image captured from Pulsar Helion XP50 for demonstration purposes. Image resolution, magnification, and field of view vary depending on Helion model. Please refer to "Tech Specs" for resolution, magnification, and field of view.

Fully waterproof
the Helion is IPX7 waterproof-rated which includes heavy rain and submersion in 3 ft. of water for up to 30 min.

Mobile-friendly (iOS, Android) with remote control and live internet streaming
The highlight of the Trail is the ability to link via Wi-Fi the device with Android and iOS based mobile units using the free mobile application Stream Vision. The Stream Vision software connects the device with Android/iOS mobile unit (smartphone or tablet) which enables you to receive footage in the real time mode, to distantly operate the device with your smartphone, as well to stream online the image captured by the device to Youtube.

Built-in Accelerometer / gyroscope
A built-in accelerometer/gyroscope improves accuracy by precisely identifying cant and angles greater than 5° with an arrow indicating the direction and degree of lateral tilting. Increased angles are denoted with additional arrows.Moreover, the riflescope can be set to auto shutdown when resting in a non-shooting position. Unit operation may be disabled when the vertical angle is greater than 70° or horizontal angle is greater than 30°. The accelerometer feature may be temporarily disabled for continued use at excessive angles.

Quick-change B-Pack power units
Trail includes a progressive autonomous B-Pack power supply consisting of a quick-detach, rechargeable IPS5, 5.2A-h battery pack designed to deliver over 8 hrs. of operation on maximum mode. Higher-powered IPS10 battery packs, as well as CR123A and AA battery cases, also are available and provide a perfect off-the-grid power solution.

Stadiametric rangefinder
Based on estimated heights of observed objects, the stadiametric rangefinding reticle makes determining precise distances fast, easy, reliable and repeatable.

High image frequency
At a high refresh rate of 50Hz, the Trail provides comfortable viewing throughout dynamic, rapid motion.

Wide range of operating temperatures

With a frost-resistant AMOLED display, the Trail thermal imaging sight is designed to deliver flawless performance at an extreme temperature range of -25° ... +50°С.

Fully-functional wireless control
The ergonomic, wireless remote control, with encoder wheel, puts the full range of the Trail’s capabilities at your fingertips for comfortable, convenient, hands-off operation.

Display-off mode

    Outstanding Into to Thermal Monoculars

    Posted by Dean on May 20th 2020

    Left a message on Friday, had a call back Monday, and had this unit in my hand on Friday. Great rental process and people to deal with at UNV.

    The unit itself is very impressive. Could tell which horse was which at 300 yards and spot anything around within 800 easily. Could tell the difference between a cat and a fox at 200 yards. Scanning a field is comfortable and easy. The color palettes aren't just marketing. They can be a huge help in spotting or reducing eye strain. The PiP zoom is also very useful. Going above 10x with this unit, you will want to use the integrated tripod mount and connect it to your smartphone or tablet. My wife loved using this unit over the PVS14 we rented as well and mandated thermal come first. "What's the point when the thermal is this good."

    Great service, cool toy

    Posted by Trace Trimble on Jul 15th 2019

    I called around lunchtime on a Thursday, and had the scope in my hands by the time I was ready to leave on Friday afternoon. Very cool device, and convinced me that I need to go ahead and buy one for keeps.

    The best monocular i've ever used

    Posted by Brooklee on Jul 15th 2019

    Pulsar really hit the mark with the XP50 Helion monocular. The size and weight is perfect for carrying on your person or in a pack for a long night of hunting. The image it produces is unreal, crisp and clear images allow you to detect animals at great distances. This is particularly useful for hog and coyote hunting and helps minimize movement when scanning a field searching for game. The color palettes allow the user to find what works best for them and I appreciate having the different color options available. Another awesome feature is the built-in video recording so you can capture your hunt, or easily record when something cool happens. Last but not least the rechargeable battery pack lasts for a whole night of hunting and saves me money by being rechargeable, yet another great feature on this unit. My favorite monocular I've ever used by far, Pulsar knocked it out of the park with this model.

    Pulsar Helion xp50

    Posted by Todd on May 4th 2018

    Tried the Pulsar XP50 and Trijicon REAP IR for a weekend. I found VERY little difference between the 2 scopes' resolution. The REAP may have just a slight advantage in resolution at longer distances, but given all the added benefits of the Pulsar, it's a no brainer for me. In the flat farm ground of Iowa, we easily spotted coyotes at 1/2 mile and spotted one pair at 3/4 mile.

    Pulsar XP50 Monocular

    Posted by Brandon on Jan 19th 2018

    Awesome experience, was able to bag 7 predators using this device. Very durable, hunted in sub zero temps with no malfunctions, very crisp clear picture. We were able to spot animals out to 1000 yards with no issues. Also, hats off to Ultimate Night Vision team, I sent several questions during the rental period and they were very quick to respond, great customer support!!

    Amazing Service and Product

    Posted by Katie G on Oct 9th 2017

    If I could give this company 10 stars I would do it in a heartbeat. Amazing Customer Service. Beyond amazing Product. This thing was a lifesaver. I used it to find my missing dog. There are a ton of features I didn't get to try yet. But I have a feeling I'll be renting one again so, there's time. =) I want to thank Ultimate Night Vision for all of their help, especially Tyler. They took a novice, I mean the most novice you can get, and gave me the assistance to feel comfortable using the gear. They went above and beyond the call of duty. I can never thank them enough. I will recommend this company to anyone who will listen. They are a 10 star Stellar business and they helped me get my dog Sam Elliot back. Thank you guys!!!!
