Next year I intend to research bioacustic in caimans` nest using the audiomoth devices.
I would like to know which is the best case (Audiomoth v1.2.0 case? Or another in the forum), waterproof and that captures audio perfectly inside leaf debris. Has anyone tested before it? Or in sand nests?

It worked.
Below you can see some photos of the case and internal apparatus that I made to micromoth. I used 5 of it in the Atlantic Forest of Brazil, near to caiman nests. It worked very well, but you need to take care of the acoustic membrane, as it was placed outside the case, it is very sensitive to physical damage.
I used a small container made of glass and plastic cover (with latches), with sponge to fill the space, li-on rechargeable battery (6800 mAh and 8800 mAh 3.7v), memory card 64 Gb, tampon (reduce the humidity), acoustic membrane.
