 Trail cameras are a great technology that most deer hunters use. When trying to identify individual deer or get a rough estimate on population, use one camera per 100 acres and place cameras near a food source. If you are trying to pattern a particular buck, target trails near bedding areas. Secluded field corners and corridors of trees between fields can be good areas to target bucks as well. Placing cameras on scrapes can yield good results to help determine movement and number of individual bucks in an area during season. If using a camera near bedding areas, you may want to leave the camera unchecked throughout that season and go back after the season to pull the card. This can keep from bumping the deer repeatedly and give you some good info as to what his patterns are throughout the season.
