OK I got my CED Millenium back this week, just finished a test for anyone who wants to know!!! I started about lunch today sun was out. I shot 25 22 lr pistol, 25- 22 lr rifle, 25- 177 cal air gun, 5- 17 rem cf, 3- 300 wsm and 5 arrows from a compound bow. only one miss reading. 4:00 pm it's cloudy 25- 22 lr out of rifle no miss readings. 7:15 sun on the way down 5- 22 lr out of rifle did not read any of those. 7:30 pm got infared sky screen hooked up. 50- 22 lr out of rifle not a single miss. I even tried to make it miss by shooting up high, but it still would get a reading. I have to take back the sux comment, I made. I guess u can get a lemon in anything. We will see how it works over the long haul. The computer hook up was also nice. That concludes my test. Moe
