Why choose radio telemetry?

Water or Land Use

Radio telemetry works for fresh water and terrestrial use.

Noise Tolerance

In water, acoustic transmitters are more susceptible to noise.

Wireless Access

Allowing internet access enables live data, and more automatic data collection.

Vehicular Tracking

It is possible to detect transmitters via plane or car.

Modular Design

Our radio transmitters are easy to customize, and add/remove sensors.


Compared to other methods, radio telemetry is one of the lowest cost solutions.
