Pick the Halo Collar 5 if your yard is under half an acre or you want fences that work offline at other properties. Pick the PetSafe Guardian GPS 2.0 if you have at least half an acre without dense trees and want longer battery life and a $99 yearly plan.
The central trade-off
Yard size. Halo states fences from 900 sq ft. PetSafe designs Guardian for half an acre and larger without dense tree cover.
Battery. Halo states up to 48 hours; Guardian up to 70 hours.
Plans and fences. Both need a subscription. Guardian's is $9.99 a month or $99 a year and saves 50 fences. Halo's Pack Membership is required for fences and tracking.
