Transmitters

ART Acoustic and Radio Transmitters

Acoustic and radio transmitters provide a means for tracking anadramous animals in salt and freshwater environments, as well as great depths and extreme shallows. This provides the best features of both acoustic and radio tracking. More…

AT Accelerometer Based Acoustic Transmitter

The Sonotronics AT-05 Accelerometer Transmitter is designed to provide information pertaining to movement of any animal or target tagged with the transmitter. More…

CHP High Powered Transmitters

High powered transmitters function identically to the coded transmitters, but have a very high power output. This allows tracking of pelagic species and tracking in large or open water areas. More…

CT Standard Coded Transmitters

Standard coded transmitters ping an aural code for easy audible detection by researchers. These transmitters for unique identification of thousands of animals by varying combination of frequencies, codes, and pulse interval (time between pings). More…

CTT Temperature Telemetry Transmitters

Temperature telemetry transmitters allow for the telemetry of temperature in the vicinity of tagged animal in addition to location and identification. More…

DT Depth Telemetry Transmitters

Depth transmitters allow for telemetry of animals depth to arrive in real time, as well as location and identification via similar coding to the coded transmitters. More…

IBT Miniature Transmitters

Miniature transmitters function identically to the coded transmitters, but are very small in size. This allows tracking of very small species. More…

PT PicoTag subminiature transmitters

These new very small transmitters allow for attachment to smaller animals than every before. More…

Receivers

miniSUR Submersible Ultrasonic Receiver

This small, inexpensive, long life unit allows for detection of fish passage within its detection area. More…

SUR Submersible Ultrasonic Receiver

This rugged, inexpensive, long life unit allows for detection of fish passage within its detection area. More…

Hydrophones

DH-4 directional hydrophone

The DH-4 provides the greatest range and precision in locating transmitters from 30kHz to 100kHz. More…

TH-2 towed omnidirectional hydrophone

The TH-2 provides a simple method for mobile active tracking: its small size and hydrodynamic shape allows for trolling at speeds up to 5 knots, while the long cable length minimizes the affect of engine and prop noise. More…
