I bought one this year and have really enjoyed checking out the footage. As Brent mentioned, even when they are "sighted in", they often are a little bit off. I do a lot of waterfowl hunting and the ShotKam is perfect for that situation as you know the birds are coming. It's a little tougher with pheasants as they have a propensity to fly away at any given moment. This matters because the ShotKam is in "sleep" mode and you have to bump the stock or press a button to get it in "active" mode. Again, this can be difficult to do as pheasant hunting happens quickly, but I usually bump the stock once my dog starts getting birdy. You can leave it in "active" mode, but it eats the battery. Additionally, I just bought a warming sleeve that holds a hot hands up against the ShotKam as it is sensitive to cold (under 30 degrees, in my experience). Without it, my ShotKam was dying in about an hour. In 50 degree weather, I could get 3 to 4 hours out of it.
FWIW, you can check out my pheasant clips. I have the GoPro footage at the beginning of the video and will note that the ShotKam footage was slowed down with Adobe Premiere Pro and starts at 5:28 on this video -
