One of my favorite times of the year is the time for setting up trail cameras. It is like Christmas morning every time I go and retrieve a memory card. You never know what you are going to find. Of course I am looking for Mr. Big Whitetail but I enjoy any critter that gets captured on a card.
I have only used one brand of camera and that is Moultrie. I have a Moultrie M 80 and D 55, and have had good luck with them so I have had no need to change. I try to set them up sometime in June and hopefully don't take him down until January. I only take them down earlier if the snow gets too deep to retrieve the cards. With our cold temperatures battery life usually isn't very good. Especially when it consistently is below 0°F. But even with those temps, these cameras work great.
I might try some other brands in the future. What brands do you like?
