A handy device for attaching tools to bags for easy unclipping for use. It features a carabiner on one end to attach to D rings, webbing straps, belts etc. and the other end has a split ring to attach tools. When you need the tool, you give it a pull, and the clip will undo. To put the tool back, put the two magnetic clips close together, and they’ll snap back in place. The magnets are strong, so can deal with quite substantial items. Snaps are also good for landing nets, allowing you to store the landing net on you and un-clip it quickly when required.
