Matt,
I'd be interested in your findings on the NVG and thermals, wonder if a digital cam would work though those...
SAAB / Barracuda sent me some samples of thier Swedish style Indivdual screen, same as CADPAT one just in the M95 Pattern, they also sent me a panel of thier Thermal ULCANS (correct spelling?) vehical cam screem too, much different then the individual stuff, but then different purpose.
I did a rather un-scientific study at nighttime with me and the swedish cam net and the neighbors three pit bulls, as far as I could tell they never saw me till I started to move and then they freaked out.... I'm not totaly stupid, 3 pit bulls.... the 3-foot chain link fence was between us. There where used to me, having been "neighbors" for years, but without the screen I couldn't go anywhere within thier sight in my back yard with them barking like mad. kneeling (with the dogs inside, my neighboor then let them out a few minutes later without him knowing I was outside) next to a tree and the screen over me from head to ground less then 3 feet from the fence they walked right up to the fence like I wasn't there, they never looked at me, they did of course looked at my own dog wondering wtf I was doing. One dog looked at me for a few seconds but from the look on his face I didn't think he "saw" me, without the screen they would not get within 4 feet of thier side of the fence with out barking or at least keeping thier distance. I stayed under the screen for 5 minutes or so without moving, then moved a little, one pitbull took off running the oppisate direction as fast as she could. The 2nd backed off 15-20 feet with a blank stare on his face. The 3rd backed off 5-10 feet and then just looked at me with a stupid look on his face, no barking from any of them. My wolf/shepard mix thought the whole thing quite entertaining. Once I stood up with the screen on the pits back off even more, removing the screen they stopped looked at me then each other and then started to bark like mad as I laughed...
I then hung the screen up in a large bush in my yard with as many of the edges as stright as possible (stright edges are easy for the human eye to pick up), backed off and after 4-6 feet lost any of the edges even though I knew where to look, moonless night.
