The Old Salty planer takes your lure down deep without heavy sinkers. While in trolling position, the planer runs at 45 angle.After a fish bites, it pops off the angle and runs straight, allowing you to reel with no added resistance. All sizes 3 and above feature a rugged stainless steel blade and large brass ring to assure a clean trip. The #1 and #2 feature a barrel swivel.
