Heat Detection

​​​​Expert eyes 24/7

The Flashmate® Electronic Heat Detector, winner of the International Innovation Award at the 2016 Fieldays, is a disposable electronic heat alert product that wh​en 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.
