The 11 inch HotChip flashers are fish catching leaders in the different types of flashers.  They are probably used in more applications that any other flasher series.  They are a trolling device that attract salmon with vibration from their kicking and spinning action. They are attached to your fishing line and then a bait, lure or hoochie is tied between 24 to 48 inches behind the flasher.  This tail leader length is the most important rigging feature in catching salmon,  See flasher rigging techniques at www.protroll.com The flasher can be dropped to depth using a downrigger, a diver or a lead weight.  Typical trolling speeds are 2.0 to 3.0 MPH    

In recent years the plaid finishes have become very popular.  Plaid reflects light in a number of directionss and also reflects a variety of colors.  This flasher is plaid with a UV purple stripe down the center. It has become extremely successful in catching salmon and is one of the top ten best Pro-Troll finishes.   You need one of these in your tackle box.
