Spro Mefo Inline Eel (Chopper) The Inline Sea Trout Spinner is a ready-to-use lure that is immediately ready for action. With a treble hook, oval snap ring and bead, it can be mounted directly on a fluorocarbon leader. The spoon impresses with its perfect casting properties, which enable long casts, and an attractive fluttering action that reliably attracts sea trout. The extremely reflective coating increases visibility in the water and makes the lure particularly catchable.
