SpotOn and Halo are both wireless GPS fences, but only SpotOn is independently tested for accuracy and proven to deliver consistent alerts and reliable boundaries. If you want the best GPS fence on the market, this side-by-side breakdown makes your choice easy.

THE SPOTON ADVANTAGE

Why Thousands of Dog Owners Choose SpotOn

Superior GPS Accuracy

Only SpotOn’s patented True Location™ tech and active dual-feed antenna eliminate GPS drift and perform in tough environments like dense woods, proven by independent lab tests.

No Hidden Fees

You get unlimited fences, off-grid mode, and keep-out zones with no subscription required. SpotOn works right out of the box—unlike Halo, which locks core features behind a paywall.

American-Made, Built to Last

SpotOn is proudly designed, assembled, built and backed n the U.S. Our premium components and 5-star customer service set us apart from outsourced support and cheaper parts.

SpotOn vs. Halo: KEY DIFFERENCES

One is Built for Serious Dog Owners. The Other... Not So Much.

SpotOn was created by the same engineers who developed GPS tech for the military. That commitment to precision shows in every test and every fence line. Halo relies on Bluetooth beacons, smaller antennas, and limited fence mapping options that often miss the mark. If you want real accuracy and real freedom, SpotOn is the smarter investment.

Collar Size Guide

Selecting the right size is important! It ensures your collar’s antenna will face the sky and receive the strongest GPS signal, making the entire system more accurate.

1. Measure your dog’s neck just above their regular collar.

2. Make sure you can fit two fingers under the measuring tape.

3. Select correct size. SMALL for dogs with 10- 14” necks (+15 lbs), MEDIUM for 12-18” necks, LARGE 19-26” necks. If your dog is in between sizes, purchase the smaller size.

What do real users say?

"We purchased 2 collars for our dogs after moving into our new home in the country. We struggled with the decision between the halo collars and SpotOn, halo was cheaper but there were zero negative reviews for SpotOn….so we decided to give SpotOn a try, as being able to trust the fence was very important to us. So extremely happy we did!! These collars have been a game changer for our dogs and their ability to run our land freely, with no dropped signals or fences. We recommend to all of our dog owner friends!!!"
