Hi Brian, One of my Audiomoths in IPX7 case was hidden near a ditch. It was left there for ten days. When I collected it, it was half under water, mic in air. Inside was completely dry, and AM was still recording. When I checked the recordings, it had been completely under water for over 24h. Whilst under water, recordings were very faint. After 24h mic was apparently back in air and recordings were fine as always.

After some weeks of experience with different configurations it is clear to me that using short cycles like 0/10 (seconds sleep/record) resulting in many files written to SDcard decreases runtime. Changing cycle period from 0/10 to 5/295 increased runtime from 3,5 days to at least 6 days, probably over 10 days on 3 Energizer Lithium 1,5V AA batteries. Triggering does not seem to affect power consumption.
