MTI revolutionized the animal tracking world in 1991 with the release of the 95g PTT-100. This was the PTT that proved it was possible to use the Argos system to track migrating birds by satellite with low-power transmitters. Since the debut of the 95g PTT, miniaturization and advances in microelectronics have allowed us to continually reduce the size of our PTTs with the goal of providing remote telemetry for all species, large and small.
