They are Browning cams, but I am not sure what model. My buddy is the cam nut and they are all his.
He has all kinds, but the Brownings are his current favorite cam when buying new ones. Our all-time favorite cam is the Cuddeback Capture flash cam. They no longer make them though, and the ones he has are slowly dropping out over time.
Due to flooding we haven't had any feeders on the north end of the farm (about a mile from these sets of feeders). That changed this past week, so hopefully we have some different bucks on the next check.
