HydroMoth v1.1.0: Compact and Efficient Acoustic Recorder for Monitoring in Aquatic Environments

The HydroMoth is a submersible acoustic recorder designed to capture sound in aquatic environments at depths of up to 60 meters. Based on the popular AudioMoth platform, it offers uncompressed WAV recording directly to a microSD card, allowing precise analysis of the captured sound. Its polycarbonate housing with a Velcro strap ensures durability and easy field attachment. It operates with 3 AA batteries and is ideal for monitoring marine wildlife, studying underwater noise, or conducting aquatic conservation research.

Underwater Case

The AudioMoth underwater case was specifically designed for the HydroMoth and the AudioMoth version 1.2.0 (without the 3.5 mm connector). Other versions of the AudioMoth fit inside the case, but we recommend version 1.2.0 to minimize self-noise in recordings. The case is made of injection-molded polycarbonate and comes with an adjustable Velcro strap, making AudioMoth attachment simple and easy. Unlike the original AudioMoth case, this one does not include an acoustic membrane. The case is compact, highly durable, and will protect the AudioMoth for long periods of time at depths ranging from 30 to 60 m.
