One of the easiest ways I have found to test the cold weather POI shift is to turn the scope on and shoot a group, then lay an athletic ice pack around the scope for 15 minutes (the soft flexible ones), and then shoot a group. If it stays, it has a pretty good chance of holding the POI in cold weather. When running this test, my Flir PTS scopes and my Bering thermals did not move, but my Pulsar Trail scopes all moved including ones Pulsar said were fixed. However, I have not tested a Thermion, Thermion 2, or Trail2. As I have stated many times, I have asked Pulsar to send me scopes on numerous occasions so I could verify, and they said they don't send out demo or test scopes. They have told Night Goggles/me, we would have to buy it to test it. If Pulsar sends some to me, I would be happy to test this.
