These long-range electronic ear tags are designed for cattle, sheep, and pigs, allowing for real-time tracking and quick inventory. They broadcast their ID wirelessly up to 150 meters and can be used for monitoring activity, locating animals, searching for inventory, and managing feeding and medication. A positioning system can pinpoint the tag's location, while a handheld reader can quickly confirm if free-range animals have returned. The tags are small, lightweight (4cm diameter, 15g), and easily applied with standard ear tag pliers, using a CR2032 battery that lasts for 3 years (at 3 shots per second). A low-battery warning is provided, and the battery can be replaced. (To be purchase with Scanner)
