The Fishpond Swivel Retractor is designed to be fool-proof.
Fly-fishing is a game of fooling, and the Fishpond 360 Degree Swivel Retractor is designed to be fool-proof. Once pinned to your vest or pack, it can rotate 360 degrees, thereby keeping what's attached accessible and untangled. No cord or wire to snap either - the retractor coil hides inside the durable aluminum retractor body until you need it.
