To the surprise of some of the people I have played with, I avoid using an electronic tuner. In my current group, the guitarist uses an electronic tuner and then I tune to him. I usually need to hear only a note or two from him to get a reference. I'm proud of my ability to tune by ear quickly and accurately - even in moderately noisy environments. And relying exclusively on your ear can be a help. Our guitarist has a problem with his guitar going flat. He sometimes doesn't detect it, so I must tell him. I think he's gotten so dependent on the tuner, that he hasn't developed a high level of trust in his ear - he's kind of shut his ears down a little. One guy I sat in with seemed perturbed at me for wanting to tune by ear. I know my approach is probably a little out of the norm, but I think it's a good thing. Any thoughts on this?
