I believe you are correct, sir. And, I believe they are a filter feeding fish that rely on the current to feed them with plankton. Seems it may be overblown a bit. Not that they aren't still a big problem though...
Interesting... I wonder how a spoon would perform at the task? I used to catch a lot of fish on a Deep Six diver right down the chute, mostly with spoons though. You're making me wonder if this might be related to those fish that strike, then drop away like that.
First year, I bolted the camera right to the tail of a Gander Mountain 12# weight. I just ground the eyelet on the tail(the one you would clip a release to) flat and the same thickness as the plastic mount on the camera housing. I got some great footage that way, but the footage was shakey, so I made a housing similar to the Troll Pro housing out of PVC fittings and pipe, and some SS hardware. Now I just mount the camera inside that torpedo housing (inside the waterproof GoPro housing, of course).
Ha, I'm really pretty conservative actually. I figured it wasn't much more risky than sending a $700 probe down there;)
That Hero 4 should bag you some awesome footage out at Yellowstone, that's for sure!
Using the GoPro has been nothing but a positive experience. It has both confirmed some of the previous theories I have had, as well as creating new ones for me. Although it is tedious to review the footage, it's pretty exciting to see what was really going on down there the day before!
This is a great topic for discussion! People can come up with so many different conclusions, but the truth is you really don't know the answer because you can't really see what is happening underwater. This is exactly why I started using a camera on my rigger when conditions are right for it.
I have been filming with a Gopro on one of my riggers for 3 seasons now, and it is hard to believe how many fish follow a bait, but don't commit. I have one clip where a Laker swims up to the bait, swipes at it, falls back, then comes back and does the same thing like 13 more times. I also have clips that show fish looking at my higher outdown bait, then shooting 15 feet deeper to investigate the bait in front of the camera. The statement that fish won't, don't, or can't feed downward is a complete falacy. They can see and feel things below them and if they are interested in your bait below them, it is nothing for them to kick their tail a couple times and get beneath it to gain an advantage and get a closer look.
I used to get frustrated when I would review my footage and see so many fish looking but not striking, but I have come to the conclusion that it is when I am NOT seeing fish that I am doing something wrong. I feel that if I am drawing them close enough to film them, or see them on the graph, it's just a matter of time before I get some takers.
