Lew, you're right, a new battery is not a panacea in preventing all the potential pitfalls in using a sensitive electronic device like the Fozgometer. And no, I don't put a fresh battery in my Fozgometer each and every time I use it. I made the suggestion because it helps to at least establish a baseline if anyone is unsure about the condition or quality of a battery. Do I recalibrate my Fozgometer every time I use it? No, but I do swap out the battery every year and I recalibrate after doing so. It's not difficult. It doesn't take much time. Not really a burden.
Now, setting azimuth by eye and ear, that's a burden. '-)
