Just read about this online and short of a GoPro like video this is done cool stuff.... Not sure I would plug this on a kayak but I'm sure in another year or so they will have smaller units... This basically answers my core question of which way are the fishing heading...
Check out the videos on the site.. Pricey but not as crazy as I expected with unit under 1,500.. A man can dream can he ?...
