Property size decides most of it

SpotOn needs at least a third of an acre, 80 feet wide at the narrowest point. That rules out most suburban lots, and it's where Halo comes in: it works down to about 30 by 30 feet. GPS drifts near buildings, so Halo recommends keeping your boundary at least 20 feet from the house, and SpotOn owners report drift near metal roofs and buildings too. On a small lot, that buffer eats a lot of yard, so walk your property and picture the line before you buy either one.

On big properties, SpotOn is at home. It saves unlimited fences, and SpotOn advertises fences of 100,000+ acres. Halo's limits are generous too, but its plan caps how many fences you can save (5 on Bronze).

Cell coverage

Both keep containing your dog without a signal: Halo's fences live on the collar and SpotOn's run on satellites alone. The difference is what you lose. With Halo, a dead zone costs you alerts and the live map until the signal comes back. With SpotOn, alerts and tracking need both a signal and the optional plan. If your place has no service at all, SpotOn without a plan costs less over time and gives up nothing it could have used anyway. See trackers without cell service.

Cost over time

Halo is cheaper to start: $633.89 in year one against SpotOn's $999 to $1,100.88. Halo's plan is required, though, so the gap closes over the years. If you'd skip SpotOn's tracking plan, the two cost about the same over five years at today's prices. If you'd add tracking, SpotOn stays more expensive. Two collars? Halo sells a pair for about $998, and SpotOn takes $100 off each extra collar. Every brand is in what trackers really cost.

Your dog's size and comfort

Halo starts at 10 pounds and weighs about 4.6 ounces. SpotOn starts at 15 pounds, and reviewers measured it at about 8 ounces. Owners and reviewers call both bulky on smaller dogs, SpotOn more so. For a big dog, either is fine.

Battery

Close to even. Halo claims up to 48 hours and SpotOn 33+ hours with tracking, more in its Extended Battery Life Mode. Treat both as nightly chargers.

Training and support

Both brands build in real training. Halo's program comes in four phases and was built with Cesar Millan. SpotOn uses a three-step method and includes a free 30-minute session with a trainer. On Trustpilot in October 2026, SpotOn held 4.1 out of 5 and Halo 3.8; SpotOn owners often praise its support, while Halo complaints center on warranty replacements and return fees.

Our verdict

Halo Collar 5 is the right call for most homes: a typical yard, a dog over 10 pounds, decent cell service. SpotOn Nova is the right call for farms, big rural lots and anywhere the cell signal can't be trusted. If your yard already has a fence, skip both and get a GPS tracker.
