I hardly every use my cam. The main lake that I fish has dirty water. Last year we used it in a odd way. We would move around drilling holes, put the camera down and check water clarity. If you could see more than a foot, move. We found that the dirtiest water held the perch. I only have success using the cam normally on one lake, extremely clear. On this lake I catch five to friends one, light bite. I do feel like it scares fish in some situations. In bay de noc this year we were marking fish constantly,but couldn't get them to bite. Threw the camera down didn't see/mark a fish in an hour. Took it out, fish all over
