I bought this unit in December of 2019. I lucked out on the serial # 91101. That’s right 91101. The unit works flawlessly and still has almost 5yrs of warranty left. I have almost 40hrs run time on it. Mainly used To hunt coyotes on the weekends. I can ID a yote at 500 and I say 500 because that’s the furthest I’ve had the chance of id’ing one. I can ID deer at 800-900 easily. I can see field mice running around in fields at 400. The unit the flat out works! I have a Velcro strip that is taped on the top of the unit for use with a battery pack. The Velcro will peel right off and if I rub rubbing alcohol on it you’ll never it was there. I came up with this idea because I run the unit for 8 hrs on 1 battery pack. No brainer right? I’ll throw in the battery pack or I’ll take the Velcro off and throw in some surefire batteries. Either way it’s up to you. If you have any questions don’t hesitate to ask. I paid 5800+ tax for this unit. Now I know I won’t get that because that’s the name of the thermal game lol priced to sell $5100 obo and I’m open to trades. I’ll take better pictures this evening. I was in a hurry this morning before work and this is what I ended up with
