Well i used my Zoom H5 today and i recorded 17 mins of a thunderstorm. It is AMAZING!!! I used 48/24 wav format and the MICS are so sensitive that it picked up a police car on the highway and a motorcycle like 4 blocks from me hauling ass to beat the rain. Ill have to use a limiter so the low freqs do not bottom out in the recording. I am now making a 13 min track with rain and thunder as the bottom of it. We will see how it works!
