Blades

• The three main type of spinner blades are Colorado, Indiana and willow. Colorado blades are the most circular shaped and displace the most water as they move through it. As a result, they are especially effective in murky water or under low-light conditions. Willow blades are long and narrow and most effective in clear water under sunny skies. Indiana blades fit the niche between the other two blade styles and work well in a variety of fishing conditions.
  
  

Components

• Spinner blades do not serve much function on their own. The spinner needs to be attached to a clevis, which is a metal or plastic piece that is threaded onto the fishing line. In most cases, anglers also put several beads between the clevis and the hook. Not only do the beads help attract fish, but they also reduce the chance that the clevis will cut or nick the knot that attaches the fishing line to the hook.
  
  

Movement

• Anytime you are fishing with a spinner blade, you must keep it moving. Its effectiveness stems from movement, and if there is none, then the blade does not turn. Because of that, most anglers who fish with spinners troll them along the bottom. It also is possible to drift them over likely areas, but make sure the boat is moving fast enough to keep the blade turning.
  
  

Live-Bait Rigs

• Walleye fishermen who use blades generally use them as part of a live-bait rig. The rigs consists, in order, of a walking sinker (heavy enough to maintain contact with the bottom), swivel, blade attached to the line via a clevis, three or four bright-colored beads and a hook tipped with a leech, minnow or night crawler. Spinner rigs are especially effective when trolled or drifted along drop-offs and weed lines.
