  1. preston.campbell

    Got this for woodland observations. First night I spotted 3 deer at 100 yds, and it was easy to understand that they were along with smaller animals like hogs. The sensor could really pick up on the deers even before I knew they were in frame, even with brush 20 yards away from me and between the deer and me. The wifi and Bluetooth work great. It’s easy to export videos to your mobile app. My kids really like watching these wildlife videos
