SpotOn NOVA kept our dogs inside the boundary on every single test — 8 inches of drift on average. That's not marketing. That's our data — and Spirent's independent testing confirmed the same results.
SpotOn NOVA GPS Fence Collar — the only GPS fence with 100% containment verified by Spirent
We walked our dogs to the boundary 5 times under partial tree cover — more challenging than open sky, and a realistic test of how most backyards actually look. We measured exactly where the collar triggered each alert in inches from the GPS boundary line. Here's what SpotOn NOVA actually delivered:
Average correction drift measured in inches from the GPS boundary line. Shorter is better.
What the range tells you: SpotOn's worst correction was 34 inches (under 3 feet). Halo's worst drifted over 100 inches — more than 8 feet past the boundary, and missed one alert entirely. With SpotOn, you're not rolling the dice.
Testing conducted by The Pampered Pup, 2025–2026. Partial tree cover environment. 5 trials. Full methodology and raw data available upon request.
Spirent has tested GPS systems for over 50 years — for NASA, the U.S. Department of Defense, Qualcomm, and Toyota. When they independently tested SpotOn NOVA, the results matched what we saw in our own backyard:

From public reviews on Trustpilot, BBB, and verified purchase platforms.
It's worth every penny I spent. He is so well trained. If I leave the collar off of him, he still will not go near the containment line.
Despite my skepticism, the collars have worked without error since installation. My dogs fly to the boundary when tempted, then put on the brakes.
I have more than one residence and it's easy to set up new boundaries no matter where you're at. Fence and collar are great.
