I know this was posted some time ago, but I might have a little to add.
I'd considered in the past going on a field recording workshop run by Francisco Lopez in the Amazon. On that page, he has some notes on his experience of the practicality of recording in humid environments:
"Because of the high humidity it is highly recommended to keep all recording gear inside water-proof bags. We haven't experienced any humidity-related problems for a very wide range of the typical digital recording devices used today. However, we do have experienced problems with most condenser microphones (humidity condensation producing noise), while this never happened with electric ones (like the ones in Zoom devices). It is thus highly recommended to bring contact cleaner and/or "Detox-it" for cleaning cables and connectors (see note 2 below)"
"[Note 2: List of previously used equipment NOT affected by humidity (all kept in water-proof bags when not in use): Digital recorders: Sound Devices 702, 722, 744, Sound Devices MixPre, Tascam DR1, Edirol R09HD, Fostex FR 2LE, Marantz PMD670, Sony PCM D50, Zoom H2 & H4 (although some people won’t recommend the last one for other reasons, namely motor noise). External microphones: DPA 4060, 4061, Soundman OKM Binaural, Røde NTG-3 Shotgun Microphone, Sonic Studio DSM-1S/H, Shotgun Audio Technica AT815ST, Aquarian Hydrophones H1a, Bat detector Pettersson Elektronik D 200. List of previously used equipment affected by humidity (also after being kept in water-proof bags): External microphones: Neumann KM184 stereo pair, Audiotechnica AT897 shotgun, Rode NT5 condensers.]"
If zenandtheart does read this, I'd love to hear the fruits of the project, sounds great.
