Depends, on my own property and my honey hole property I will usually check every 3 or 4 days, other areas usually once a week or every other week.
depends on what time of year. Right Now every two weeks because I'm in video Mode for about 15 seconds per trigger. The card will be full after the end of the two weeks. As I'm getting closer to patterning deer I check them every week. And as I'm getting to the rut phase I check them every time I hunt. The best thing is I can view them in the field on my cell phone to see what was going on from one day to the next. here is the my first couple weeks http://www.youtube.com/user/Soloarcher
Never more than once a week. Usually every 2-3 weeks anymore. I have went 5 weeks. I used to check them much more often when I started getting into cams for the first couple years. Now I sit back and wait.
