307kHz HR3接收机

The HR3 High Residency Acoustic Receiver is an excellent choice for tracking many fish with higher accuracy than ever before using the V3 307 kHz acoustic transmitter and the HTI 795-series transmitters.

The 307 kHz system was designed specifically to allow researchers to monitor or position many tagged animals with sub-meter accuracy and to provide high performance in noisy, high flow and reflective environments, such as around hydropower facilities.
