Good to see you back, Ken !! Nice video
While I understand the wonder of seeing, firsthand (via camera), what the depthfinder is showing .... I think I'd be too excited to get a bait down there among all those Crappie, to spend much time watching them on "tv"
With your waters being clear enough to see/film that good, over that much distance .... why not try and capture the Crappie's reaction to a jig (or minnow). And the reaction of the rest of the school, to one being caught & removed from their midst. That'd make for some good instructional video and discussion material.
Thanks for posting !!
