The 395-Series Data Logger is HTI’s smallest, most compact data logger for acoustic telemetry (tag) studies. It provides a simple cost-effective means of recording the time-stamped presence of fish tagged with HTI Acoustic Tags. It requires an external, unpowered hydrophone. Whether you choose an omni-directional or directional hydrophone, fish detection range is up to 1 kilometer (3,280 ft). Tags are detected and identified simultaneously, and are immune to data collisions and false positives.

Use it as a stand-alone unit or in HTI’s briefcase-sized, field-ready, portable case - the 395 Data Logger conducts off-the-boat mobile studies or from-the-shore studies. The maximum hydrophone cable length for the Model 395 is 229 m (750 ft). With additional units, researchers can track acoustic tags in 2D or 3D.

At a power consumption of 2.5 watts, the unit can operate to ~18 hours on a single rechargeable battery. Add an external 12 VDC battery and battery life is extended to ~50 days. An AC adapter is included and solar power is an option.

To store acoustic telemetry data, the 395 Data Logger includes a 2 GB flash drive, has Wi-Fi/Cell modem communication options. With that, your telemetry data can be accessed via flash drive, via remote communication option, or directly connect your laptop and immediate view a real-time display of data via HTI’s newest software application exclusively for mobile studies, MobileTag.
