Overview
A GPS based wireless containment system for medium to large dogs, using a rechargeable dual mode collar and a custom boundary set through the system rather than buried wire.
Unlike a traditional wired underground fence, this system relies on GPS to define a boundary up to 6561 feet in radius and runs without an ongoing subscription fee, which is the main point worth checking against competing GPS fence products before buying.
- 6561 foot radius range
- Dual mode GPS collar
- IPX7 waterproof rating
- No subscription required
Who it's for
Owners with larger outdoor properties who want boundary containment without burying wire or paying a monthly service. Not intended for small dogs given the medium to large sizing.
Strengths and trade-offs
Drawn from this product's published specifications.
- No subscription required
- Large boundary radius
- IPX7 waterproof rating
- Dual mode operation
- No manufacturer data on battery runtime or correction levels
- GPS accuracy near trees or structures is not addressed in the listing
Performance notes
The collar reads GPS position against a boundary you set and delivers a correction as the dog nears the edge. It carries an IPX7 rating, meaning it can handle submersion rather than just splashes, and runs on a rechargeable battery instead of disposables.
