I know it can be tough to resist the temptation, but checking your game camera too frequently can have negative effects on the number of images you capture.  As the deer season approaches, you also run the risk to negatively effecting the quality of your hunt.  Scent you leave in the woods and the act of jumping up deer can have them raising their guard the next time they pass through your favorite hunting spot.

Get to know your game camera, and determine how long the battery life is.  Always use the same brand and type of batteries, and always put fresh batteries in your camera.  Use the largest memory card that will fit in your game cam.  Consider shooting at a medium resolution which will reduce the file sizes of the images stored to your memory card.  Try to delay your visits to your game camera based on your battery life, or image capacity.

The last thing you want to do is return to the woods and find dead batteries or a full memory card.  So get to know your game camera, practice some patience, and see if you get more and better pics.
