If I'm not mistaken, that's a PVC cap screwed into the seat. And I thought it was just me. I'm guessing you mount a homemade PVC rod holder or something in it. I built and rigged a 3 pole holder on an 18 inch horizontal tee about 18 inches high. Been happy with it for 20 years.
Its dual purpose, one for mounting a camera on a piece of pvc pipe and the other purpose is i'll take the cap off and there is a steel plate for a spider rig setup. I can also use the same setup for catfish in the back of the boat. I'll try to explain it better the next time I'm on the water. Thanks for the input and watching!
They are a round soft plastic or rubber ball that has fish attractant infused in them. Unlike the crappie bites, they don't dissolve in the water over time
