Halo Collar 4: Versatile GPS Dog Fence for All Environments
The Halo Collar 4 boasts dual-frequency GPS, accessing six GNSS satellite systems for exceptional accuracy in diverse terrains, including urban, suburban, and rural areas. It offers real-time tracking, activity monitoring, and customizable virtual fences.

The collar features a long-lasting battery (over 30 hours) with a convenient magnetic charger. Its rugged, IP57 waterproof design makes it suitable for various conditions, including swimming. It is compatible with a wider range of dog sizes and ages.

Feature Comparison: PetSafe vs. Halo
Both collars provide essential features like real-time tracking and customizable correction methods (tone, vibration, static). However, the PetSafe excels with its longer battery life (up to 72 hours) and accommodates larger dogs (over 30lbs).

The Halo Collar 4 shines with its superior GPS accuracy across diverse environments, smaller dog compatibility (over 10lbs), and additional features like activity monitoring and a return whistle. The Halo also allows unlimited fence storage while PetSafe limits it to 20.
Setup and Fitting: A Hands-on Look
Setting up both collars involves defining virtual boundaries on a map within their respective apps. The PetSafe may take a bit longer (1-2 hours), while the Halo app streamlines the process. Testing the boundaries is essential to ensure accuracy.

The collars themselves fit like traditional collars, with the Halo Collar 4 offering a sizing kit for precise adjustments. Both are comfortable for dogs within their specified weight ranges. Remember to ensure proper fitting to avoid discomfort.
Conclusion: Which GPS Dog Fence is Right for You?
The best choice depends on your specific needs and preferences. The PetSafe Guardian GPS Plus is ideal for owners with extensive properties and a need for longer battery life. Its strong performance in open areas and simple functionality make it a compelling option for larger dogs.

The Halo Collar 4, however, offers superior accuracy and versatility across varying terrains, making it suitable for urban, suburban, and rural environments. It's a better fit for smaller dogs and offers more features, including activity monitoring. The superior accuracy and the wider range of dog sizes make this the better option in many cases.
