I use them for videos and I ship the 1" squares with the thermals I sell so people can get a better zero than using something cold or hot.
Does not make a difference.I was thinking about just buying the squares. They have tan and green, which ones should I get?
That's exactly what I use. Except here up north, it gets cold real quick. I stick it to an old file folder, taped to my target board, no problems out to 200 yds. I also use it for my Nemesis WP.I have a roll of foil hvac tape that I keep in my truck. I checked my zero last night in the cold wind and I tore off a 4x3 inch piece and put it on some cardboard and just leaned it back against a tree. It showed up good at 100. Wasn't like during the day but it worked.
I’m worried because I could not figure out how many come in a pack for the price posted that it must be a pack of one?Well, they certainly seem unreasonably expensive, LOL.
