|Application=Used with HTI-96 min hydrophone <br> Drifting measurements using a spar buoy. Continuous sampling at 96 kHz.
|Pros=Programming and deploying the device is simple and it has an external LED to confirm operation. The hardware is well constructed so that the different gain settings and output can be easily measured right from the board.
|Cons=The device is not designed for long-term deployments. The battery is the limiting factor.
|EaseOfUse=It is quite easy to use and the output is .wav files.
|Software=The software is easy to use and as previously mentioned there is no proprietary format for the audio.
