Lotek’s Vaginal Implant Transmitters are designed to indicate when birthing has occurred in species such as deer, bison, elk, bighorn sheep and pronghorn. The transmitter is implanted into the vaginal tract during gestation and will be expelled when parturition occurs.
VITs can be used on their own or part of a system with satellite birth alert capability. Operating life can vary depending on application and study needs and objectives. Please contact one of our Telemetry Specialists to discuss your study needs.

1. Estimated life at 38˚C using battery manufacturer’s information. Actual lives may vary at the extremes of the operating temperature range by up to 50%. Life calculations based on continuous operation at a pulse rate of 40ppm when implanted. When expelled transmits at 80ppm reducing life.
Technical Specifications:
Operating temperature range: -30°C to +50°C
Temperature accuracy: +/- 0.5˚C
Pulse rate: 40ppm implanted, 80ppm expelled
VHF frequency range: 148 to 174 MHz
