One of my favorite gadgets around the farm is my remote control electric fence tester. We spend a bit of time messing around with electric fences. Most days we put up temporary electric cords to ensure the cows have just the right amount of pasture to eat and all the stormy windy weather we have had of late means fence repairs are a regular task.
The remote control electric fence tester enables us to turn the electric fence on and off from anywhere on the fence network around the farm. No needing to head back to the sheds to turn off the fences to do repairs and less zaps while fixing live fences.
It aint rocket science but it’s another example of technology assisting in agriculture.
