I have a vendor I buy from is big into this and the electronic's has really changed fishing. Just as said above they look for fish on graphs and cast to them. Like 30 to 40 k for all the new stuff 3 graphs in front alone.
I was surprised at the amount of people that were here for that. Made the walleye tourneys look bush leaugeThere was an event on Oahe last year out of Mobridge I think, not sure what kind of crowds they had. Also remember that this event was the Superbowl of bass fishing which is why the crowds were a lot bigger and just the fact that bass fishing in general has a much larger audience the corwds and money are bigger than walleye.
