What brand of nails are you using in it? I have the 16ga and 18ga cordless nails guns and it says right in owners manual to use only paslode or dewalt nails and thats what i use and have had no problems
Hope it is a thermal imaging camera we got one at work and it's sweet but ours was really expensive hopefully it is cheaper and hopefully it has a removable memory card to store and up load pics to computer
