I'm looking to buy a thermal handheld scope I've have had 3 neck surgeries and have a 4"piece of metal in my neck I can not use my gun as a spotting scope. I am using a Amasight Zeus Pro Thermal 640 4-30 x 100 60hz on my gun and I have a Armasight co -x Gen 3 Alpha night vision clip -on and I use a PVS 14 to use when am walking around. I really would like to have a thermal handheld. This is the best forum to get the right information I would like to say thank you for all your help.
