A high quality thermal imager, through and through.
I've tried a few 640 core thermal cameras, the Telos XP50 is the definitive winner for me. The thermal sensor is the best I've tried, and highlights thermal signatures extremely well. It has a dual band (2.4ghz, 5.0ghz) Wi-Fi output, and the ONLY thermal camera I've found that actually streams the video feed in REALTIME, with no noticeable delay. Build quality is excellent. No dead pixels. The USB-C connection gives me confidence that it won't break or wear out quickly. Some devices have those connectors which feel like they're not plugged in completely or just very loose, this is not one of those devices. It has a 5 year warranty when registered. They even get back to you and let you know the device is registered and what the warranty end date is. The app is great, with 1 caveat. I have an iPhone 12, and I have to disable the cellular connection before it lets me connect to the XP50 through the Stream Vision 2 app. After it makes the Wi-Fi connection to the XP50, I can reenable cellular data and everything works fine. The app offers 16GB of free cloud storage. And you can access the Stream Vision cloud from your desktop or laptop. I like being able to transfer media from the thermal imager to the desktop without needing to plug anything in. There are multiple ways to charge the battery too, so you don't have to worry as much about wearing out the USB-C port on the device. You can charge it through the USB-C on the XP50 itself. The battery itself also has a USB-C charge port so you can charge the battery directly. The battery also supports Qi wireless charging. Also you can charge the device and use it at the same time (supports power banks). There is an option for haptic feedback on button presses so you feel exactly when the button registered your input. This feature ended up being more important than I realized as there are many button presses which require holding for a few seconds, and it's nice to get some feedback as to when that starts. Cons: The FOV is a bit narrow for my liking, as I am used to smaller lenses with lower base magnifications.

100% useless app
I can't stand the app. I honestly don't think there's ever been an app I hate more than this one! Apps 10 years ago operated better than this one! The thermal imaging is amazing but if you plan on getting your files off of that thermal camera good luck! I'm a guide in Yellowstone national Park and I plan on covering up all of these logos until I get some sort of sponsorship, vortex optics is getting a lot of sales from me. I'm sick and tired of selling for a company when I get nothing in return. You missed out on a ton of sales! I took it out this weekend and had 4 different people ask to see what we were looking at. Once they saw the immediately wanted to know the brand lol sorry!

Glad I went with the Telos!!
This thing has been amazing! You won’t find better image quality and reliability in a monocular like this just anywhere! I have the XL 50 LRF and the range finder is very quick on picking up distances…Super pumped I went the route I did and got the telos!

I Love It
So far I love it due to ease of use and image quality. I'm only giving it 4 stars due to the app not working right. It loads right and the remote control works but that's about it. When you connect wirelessly it logs you out of anything else including your router so no internet while it's in use. Also, the transfer and view video option doesn't work so you can't use the app to review videos or transfer them to your phone or PC. The good news here is you can transfer videos via USB cable. Otherwise, it works really well and is a great tool.

Brand New with Issues
Showed up with a firmware installation issues, flashing red inside the thermal. Frustrating because I had a hunting tripped planned around its arrival. Sending back to Pulsar to fix these issues while being brand new is ridiculous when you spend this kind of money. Plus… I have to pay for shipping to Pulsar.

Bad product!
So far i belive it's drasticly overpriced. nor can I see a thermal image thru a wall or door, barely a curtain. No Good! avoid!
