The HC11G-191 is a 12 hour glow blade with a light green paint stripe on top and embossed silver tape on back.  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    

The Coyote Green Glow flasher is a hot ticket.  It is on the top ten list of the most productive Pro-Troll Hotchip flashers.  The light green finish on the glow blade seems to be very attractive to salmon.  Fish it deep or fish it shallow.  The #191 Coyote and the #188 Splatter Glow are similar in appearance and function.  Both are good. You will not miss with one of these in your tackle box.
