Last year I started out with one cam and checked it every three or four days. Mine are strictly for trail useage, so I wanted a good area survey of what was happening and where, so I was constantly moving It.I have added more cams this year,and will rotate visits and stay out ofeach particular area for a longer period of time. I practice as much scent control as if I were actually hunting, and I think it helps some, although there is always somedisturbance, I am sure.
