Heat Detection

The Flashmate ® Electronic Heat Detector is a disposable electronic heat alert product that when applied, monitors riding activity and works out when a cow is in standing heat. Test results are proving an increase in 6 week in calf rates. Patents pending.


Flashmate is fixed on the cow’s flank beside the tail ridge so it maximises retention and doesn’t interfere with tail paint application. Using simple installation and maintenance instructions ensures even first time users of Flashmate can achieve expert level heat detection.
