The problem with online discussions about tuners is that many of those who post have never used one, or if they have they did not really put much effort into making it work. I got a friend, who shoots short range group, and does his own barrel work, started with tuners. He will never go back. They absolutely work. It is not that you have to use one to win matches, but they do make small adjustments in tune a lot easier, and I have see where his smallest groups have become more frequent and are on average smaller. From his experience (he does a LOT of testing) using a tuner broadens nodes, and broader nodes are easier to stay within under changing ambient conditions.
