Question: Can this be used to see heat from a body? Or is it just a very good low-light vision?
Document: This product is very lightweight yet high quality. The on board ir illuminator can light up area with no other natural or artificial light. I would recommend this to any hunter or anyone who would want to acquire low cost-high quality night vision.
I just received my Night Owl and considering the low price, I am pretty happy with it. Once you get it adjusted, the picture is really clear. Like most all monocles the field of view is pretty narrow. The distance is pretty good. It is small and light. Over all, 4 out of 5 stars. Don't expect military quality, but if you are looking for a small, inexpensive, digital NV, this is a good pick.
This Night Owl Optics "XGEN 2X Digital Night Vision Monocular" is a good value for a very functional, low-end night vision monocular. The monocular is very small and lightweight, making it perfect for camping or adding to a "Bug Out Bag". The optical quality is better than expected and the IR emitter does a nice job lighting up a dark room. The unit has two lenses, each with a focus that must be set in conjunction to optimize the picture clarity.
It looks good and does work but what you see in the dark looks more like your worst nightmare than night vision. The field of view is very limited and it is difficult to distinguish anything. My test lasted about 10 minutes so my review will be equally brief. Everything was very fuzzy even when adjusted and vision through the unit was very uncomfortable. To be fair, I am not usually thrilled with looking through binoculars so looking through a lousy monocular type device was even more uncomfortable.
Ok. So i intended to use this for hunting. I hunt wild boars in the evenings. Therefore, NV is a very important for me.My first impressions can be summoned in pros and cons.PROS: small, light weightCONS: eats batteries, makes loud clicks when you turn it on (and this is not just one click, because in order to see in pitch dark, you have to click like 5 times to get to the highest IR illumination.
If you want a little and cheap night vision, buy this one. It's low weight and you can carry it easily.
Excellent for night vision at such a low cost, impressed by the rugged durability to this thing....simply amazing durable product.
I use this for night time wildlife viewing and for trekking through the woods at night. It is fairly well constructed and the battery life is pretty good. A great all around use night vision device.
For the price this night vision monocular works for my purpose. Although I bought this to be able to see deer around my property still have not been lucky one passing by at night. But it works well being able to see lit up my acre property in pitch darkness country farm.
I think C.Hill did a good job of rating and describing features and operation of this little XGen 2x Night Vision scope, and I second Hill's conclusion about using standard AA batteries verses most other models using a special Lithium 123 battery that costs $7 and is, of course, not rechargable.So this review is to add some application context.
Answer: yes
