I consider myself to be a veteran of trailcams, having owned many brands and types over the years. But I was completely stumped by the leaf River when it came time to program it. I ended up calling them and they were very helpful over the phone. And don't worry, it's not like when you call Moultrie, you get somebody right away. As far as the SD card goes, I would ask them when you call what card they recommend. I have used the sandisk with no problems. Good luck!
