Absolutely the best thermal scope..hands down - ATN OTS 4T 640 4-40x Thermal Smart HD Monocular

I purchased this thermal scanner almost 2 yrs ago to help with predator control. That decision has increased my predator harvest by 20 fold. ATN has the best product selection and customer service......hand down. The battery life is the best on the market. With all the tutorials available, using my THOR 4 is effortless and they will guide you thru any situations. With Any other questions or situations, ATN's customer service is the best. Their knowledgeable personnel with help and provide you with solutions/answers to rectify all of your requests. I highly recommend ATN products and customer service
