You can never have too many memory cards! These SD cards work for all SD-compatible game cameras. Having extra cards eliminates the need to scroll through images in the field, using up precious battery life. Simply pull the existing card, replace with another and view the contents at your leisure on your computer at home! Having extra cards is a great way to share photos with friends and relatives as well. Stealth Cam recommends at least two cards for every camera you have in the field, so you can swap the card in the camera for a fresh one quickly and disturb the area as little as possible.
