Passive Tracking
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…
Logger
DTL-08 Depth and Temperature Logger
The DTL-08 records events triggered by user-configured depth settings, then will continue recording at programmed intervals, allowing for 500,000 continuous measurements—enough for recording over a years worth of data taken once per minute. 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…
