Ever since I retired from the military I've been wanting a good quality thermal imaging scope for hunting, camping, security and nighttime viewing on my large property but all the other brands were always too expensive for my budget. When I came across this HTI HT-C19 35mm 640 Thermal scope for only $1499usd I had to give it a try. Shipping from China was under 10 days to me in the U.S. and I am very happy with my purchase so far. This HTI made Thermal imaging scope is every bit as good if not better than all the other brand name scopes on the market that cost over double what HTI is offering for this one. I am truly impressed with the image quality and features of the HT-C19 scope! They hit a home run with this product. I have a successful YouTube channel that I posted this thermal scope on outlining its amazing performance. You can view my video on my YouTube channel on 2AR Tactical. You won't be disappointed in the quality of this scope for only $1499! You won't find a better scope for this price. Believe me I've looked and shopped around and the other brands that cost over $3000 for a 640 scope with a 35mm lens. I'll continue to make update videos of this awesome thermal imaging scope for hunting, camping, security and nighttime viewing. It's a winner!
