This Vision holder is designed for anglers who frequently change their tips or alternate between different diameters of nylon and fluorocarbon. The spools stay grouped together in one place, which saves you from having to rummage through a pocket when you need to rebind a leader or rig. The rotating spools make it easier to grab the line, especially when working with cold or wet hands. The quick-release clip allows for easy attachment to gear you’re already wearing at the water’s edge. It’s a discreet but very practical accessory for organizing the spools you use on every fishing trip.
