So I am a first time trail cam user and picked up 3 Tactacam Reveal XBs. I've played a lot with the sesnsitivity settings, but over the last 2 weeks I've had hundreds of photos of nothing and 2 images with animals in them. I know whitetail does move through my place daily because I see them every morning. I realized after the fact I skipped the fine print and bought U1 instead of U3 class 10 SanDisk Ultra 32 GB cards. Does this make that big of a difference? I see some folks when I search troubleshooting saying they have no problems with the U1.
