Telling someone how to jig is difficult if not impossible; especially when we are talking about doing it from a canoe.  You really have to spend some time in a boat with someone who knows what they are doing and why they are doing it and ask questions as you watch them fish and as you are fishing yourself.  It's not rocket science but there is a method and technique for optimal results.  I would rather soak a jig than cast a crank bait any day.
