Sigma Eight Inc. (SEI) develops and produces state-of-the-art radio wildlife tracking equipment and systems. Having expertise in the industry dating back to 1993, we have provided services in some of the largest studies of wildlife migratory patterns, prominently fish in North American West. Our devices can be fitted to nearly any animal and can be customized to be almost any shape or size. Radio tracking is a cost-effective way to observe the behaviour of animals compared to other available methods, enabling researchers to track large groups for a relatively low cost. Receiving systems have also been developed to autonomously collect and send data to a centralized server, making it easy for biologists to access. Having online data also enables the researcher to see any issues developing, and troubleshoot them before it has had a large impact on the study. We are always open to working with the wildlife preservation community and providing the most cost-effective solution for their radio tracking project, when others have said it was not possible.
