    Excellent product

    This is the most advanced thermal monocular I've ever used before. Unit has a new sensitive sensor and shows you a perfect image. You can detect a large animal from over 700 yards away and make a positive identification from around 200 yards away. The coolest thing in this thermal is the battery life. The manufacturer declared 18 hours battery working life. With most thermal monoculars, you typically get near 4-6 hours of battery life. It also comes with the ability to dual-stream video recording. You can easily record a video in HD quality or stream it to a smartphone or save files on the SD card. You won’t find another thermal with this price tag with the kind of features and performance it offers.

    Nice built quality

    I really love this thermal monocular. I have a lot of fun using it. I no longer hunt, but still love wildlife viewing. Not so long ago I was on a seven day camping trip. I could see some squirrels in the trees at night, and I was really surprised to see how much fields and clearings came alive at night with rodents. The video features are amazing, especially in 4k quality. I brought some excellent videos of wild nature that my family watched with a lot of fun. The battery life is unbelievable. Haven’t tested all the way to zero - but I’ve used it 2 nights without charging.

    Great thermal monocular with a lot of video features

    I bought this thermal gadget for hog hunting. It seems really durable and well made. Figured, I would need the 1-10x magnifications for its field of view, but at the end I got the 4-40x magnifications. It has better detection range, which is more important for me on my night hunts. The battery life is 5 stars. Manufacturer declares 16+ hrs. I think it's true. It worked all night on my last hunt and it is still alive. I am very pleased with this product and would recommend it for night hunts.

    Good purchase

    I've been using this at work for the last 3 weeks for detecting thermal leaks and electrical problems. But now I have a new hobby. I can see and record videos of meth monsters and crack heads. The drug dealers can't lay up in deep shadow areas any more. I am also able to estimate the length of time a vehicle has been parked by checking engine heat. Manufacturer declare a 3000 yards the human detection range, and it's really true. The picture and resolutions are perfect. Highly recommend this unit.

    Cool toy

    Cool toys for big boys. Exactly what I needed. Finally, technology can offer what I've been dreaming of since childhood. Excellent for spotting. Much better than NV. It has a lot of video features, can share video via wifi and has a good battery life. I've looked at so many before buying this one, and nothing compared for style and price
