For most people, it's not something you can just throw on the boat and instantly become a dominate crappie fisherman.
I understand and agree with a lot of your post but if I could pick this part here. I feel like this is where my worry with it comes into play. Lots of people are buying it trying to do that. I swear if it wasn't so impressive I'd say it was almost gimmicky but the problem with that argument is that it can and does work/help. It may not put fish on the hook but it's going to put a lot of people on fish. It will be interesting to see where it takes us going ahead.
I'm all for people fishing and catching fish but the more I saw of it over the winter, heard from others who had it or fished with it, and read about it online I've just changed my about it. I try not to complain and will always congratulate someone on their catch I just think big picture wise it will do more harm than good.
