Hey SF. The install video is with a Baitrix. They work very well in Jughead but you have to pull the metal out of them so they swim rather than roll. I'm sure they work great on salmon, hali's, etc.
You can even inject scent into the cavity where the metal was... don't tell anyone 'bout that one tho.
I have underwater video somewhere in this behemoth pile of files... I'll try to find.
