The 8 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    
The White Glow Hotchip flasher is good for fishing deep where it is dark (usually 100 feet down or more).  Sometimes it also works better than colored flashers a shallower depths. The blade of this flasher is a shiny white, the top of the flasher is covered with premium white glow tape and the bottom is finished with embossed silver tape.  Don't be afraid to try it when nothing else works.
