The “fish finder” he shows is actually a Carolina. A true “fish finder” rig uses a sinker slide and pyramid weight and is used in heavy current.
When used in the surf the fish finder is also called a drum rig and has 3ft of heavy leader the weight slides on and then a swivel on each end one side for the mainline and one side for a 3-6” of leader for the hook.
The “drum rig” is my go to for leopard sharks in the surf.
