Excellent and easy to use. Works well with eyeglasses when mounted on a helmet.

I have been using the sidekick 640 for about 2 months now. It’s very lightweight, and super easy to use. I’m partial to the detect setting because if you have an issue collimating the two picture into one, then this is the best thermal monocular. The detect shows heat in a bright orange, so it makes it very easy for your left eye to pick that up and then you can focus on it. The larger field of view makes scanning much easier. You can really save your neck because of this. I have used infiray and irusa products and this is by far my favorite. I love how you can move the screen horizontally and vertically to get it adjusted just right for your eyes. Pair this with the ravyn group bridge, and it is perfect for helmet mounting with a PVS-14. Running this unit with a battery pack makes it run for as long as you want. I couldn’t be happier with this purchase. With a military discount I paid only 2400. You can’t beat the price, even without a discount. I couldn’t be happier with the sidekick 640.

The ATN x-sight LTV performs well. Video is crisp and clear. Night vision distance would probably improved with larger infrared light. Easy to sight in. Works well.

This magnifier is a well-made product for the price. I ran it first with a large MOA red-dot. That was a mistake. After running it with a smaller diameter red dot I was satisfied enough to keep it on the rifle. Anybody can mount it and if need be, adjust the quick attach/detach lever. Its light and pairs well behind high quality red dots. The product itself is great for the money. If I were to advise someone who is interested in a magnifier, I would tell you to make sure you use a high quality, small reticle, red dot sight to pair it with. It looks cool behind any 1x optic but in order to be practical you need to consider the set up.

Very pleased with this excellent compact thermal monocular. Outstanding clarity and definition in a 320 resolution thermal. The best value for the money in a thermal monocular hands down

So far so good on my Armasight NVG kits. The NVG's work great. Everything was packaged nicely for shipping and the communication was great with Ironclad Sentry.

This unit fit Thermal Side Kick 640 absolutely perfect. It is very solid and stable. but if you are looking to have PVS-14 added with the Thermal. This is not the unit for you. You should go with the Wilcox mount instead. So, you only spend the money once. Overall, I am happy with the unit.

This unit is wonderful! You pretty much get what you pay for, it is compact with good strong housing. This unit also comes with warranty and extended warranty for free. The most important thing is their customer service is second to none. They have very fast respond and are so willing to help you with all your problems. I highly recommend buy your equipment from Armasight
