Free: Contests & Raffles.
Just remember with the Bushnell Trophy it only has a 2 gig card size and if its out in a busy area for a while it will fill the card up. The Moultrie I40 has a great battery life and can take a 4gb card. Ryan has a decent breakdown but there are so many other trail cams out there.
Not sure where the test results on the Moultrie D-40 came from but I love mine and the battries last over a month with hundreds of pics taken.(we didnt get very cold here while mine were out) Mark
The I-40 works great for me as far as winter use and long battery life. I also leave mine out up to 5 months over the summer with no battery life problem. I have a few Stealths with external batteries that have treated me well also. I am just figuring out the external battery for home brews but the clarity can't be beat.
