I've been using 2 Plotwatchers this year. They are great for watching fields to pattern deer. As some have said, judging deer from more than about 20-30 yards is difficult but consider you wouldn't have had the picture at all with your traditional trail camera. I've gotten up to 10 days on 10 seconds with a 4hr midday skip. For those that aren't familiar; the camera takes a picture every 5 or 10 seconds, turns on at daylight, can skip the middle of the day to conserve batteries, and a full day can be reviewed in about 10 minutes or less. I've got pictures of a bachelor group of 9 bucks in October that walked through a field. Would have never put a trail cam there. I'm also using it to pattern deer activity based on lunar phase and weather to better understand deer movement. I've found that some of the better traditional trail cameras take great pictures if the deer is moving slowly and within about 20ft. Also, who cares what is moving at night? I can't hunt deer at night in Alabama.
A couple pics from my Plotwatcher.
