The Fenton Ghost Fisher is one of Fenton Works' many gadgets. It is a fishing line coated with a special resin that ghosts can't break.
The Fenton Ghost Fisher looks like a normal fishing pole with a glowing fishing line. The pole is collapsible into the handle, leaving a small metallic cylinder.
In "Public Enemies," Jack attempts to use it to capture Danny Phantom, but is unable to use it as it becomes tangled.
