What our customers say
Trusted by farmers worldwide
From Australia to Europe, thousands of farmers trust ZapSense for safe and easy fence testing
Very effective and easy to use.

Impressed by this little tester. Simple and great to keep on my keychain.
Know your fence is working before your animals escape
A failing electric fence means escaped animals, damaged property, and costly vet bills. By the time you realize your fence is weak, it's already too late. Manual testing is dangerous and unreliable.
Wireless testing: No contact with the fence required. Stay completely safe.
Instant results: Green light means good, red means fix it. Clear answer in seconds.
Keychain size: Always with you when you need it. Fits perfectly on your keys.

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.
Made in Sweden
Developed and Manufactured in Sweden
Every ZapSense is hand-assembled by us – tested, packed, and shipped directly from our farm. We're not a big factory – just two people making sure every device works perfectly before it reaches you.
