Born on our goat farm in Sweden
Life on a farm teaches you that a fence is only as good as its power. After chasing our goats one time too many, we knew we needed something better – a tester that was always with us, simple to use, and reliable.
That’s how ZapSense came to life, crafted by farmers who know the challenge firsthand.
