GPS dog fence vs invisible (buried-wire) fence
Buried wire or satellites: which fence keeps your dog in, what each one costs, and which yards each one suits.
Halo Collar 49.2/10Read the review
An "invisible fence" is a wire buried around your yard: a transmitter sends a signal through it, and the collar reacts when your dog gets near. A GPS fence does the same job with satellites and no wire. The buried wire wins on precision and on tree-covered lots; GPS wins on setup, portability and odd-shaped land. Interestingly, the biggest buried-wire brand, Invisible Fence, now sells a GPS collar too, and its parent company, Radio Systems Corporation, also owns PetSafe.
How they compare
| Buried wire | GPS collar | |
|---|---|---|
| Boundary | Exactly where the wire is | Drawn in an app, can drift a few feet |
| Install | Trenching, or a dealer install | None: charge, draw, train |
| Trees and buildings | No effect | Reduce accuracy |
| Smallest yard | Fits small lots | 900 sq ft (Halo) to 3/4 acre |
| Travel | No | Yes, the fence goes with the collar |
| Monthly fee | None for the fence (batteries or service plans vary) | $0 to about $10, depending on the brand |
| Live tracking | No | On cellular models |
What each one costs
Invisible Fence does not publish prices for its buried systems: its cost page says services and pricing vary by location and sends you to a free local consultation. It does say that, on average, fencing a quarter acre with its system is 45% to 80% more cost-effective than a traditional dog fence, and it offers financing through local dealers.
GPS collars have public prices. Across the GPS fences we compare, the device costs $199.99 to $999, and the 3-year total, plan included, runs from about $200 (PetSafe Customizable) to about $1,281 (SpotOn Nova with tracking). The Invisible Fence GPS Flex is $599 with a year of tracking, about $797 over three years.
Which one suits your yard
- Small lot, big trees, or a boundary that must follow the property line to the foot: buried wire, or the PetSafe Stay & Play radio fence if your yard is roughly round.
- Half an acre or more of open land: a GPS collar. See the main ranking.
- You rent or move often: GPS, since nothing is buried.
- You also want to find your dog if it gets out: a cellular GPS collar (Halo, PetSafe Guardian GPS 2.0, Invisible Fence GPS Flex).

GPS dog fenceSpotOn GPS Fence Nova EditionQuestions to ask before you buy either one
- For a buried system: what is included in the quote (wire length, collar, training visits), what happens if the wire breaks, and what the collar batteries or service plan cost each year.
- For a GPS collar: the minimum yard and the narrowest width the brand supports, whether the fence keeps working without cell service, and the plan price after any free period.
- For both: the return window and the warranty. Invisible Fence advertises a money-back performance guarantee and a minimum one-year equipment warranty on its fence packages; most GPS collars here carry 1 year.
- For your dog: the minimum weight or neck size, and whether you can train with tone and vibration only.

Frequently asked questions
Is a GPS fence better than an invisible fence?
Not in every yard. A buried wire is more precise and works under trees; a GPS fence is easier to install, portable and adds tracking on cellular models.
How much does Invisible Fence cost?
Invisible Fence prices its buried systems by local consultation and does not publish a national price. Its GPS Flex collar is $599 on its online store, first year of tracking included.
Can I use a GPS collar with an existing buried fence?
They are separate systems, and their collars are not interchangeable. Ask your fence dealer before mixing brands.
Can I take a GPS fence on vacation?
Yes, that is one of its strengths: the fence lives in the collar, so you can draw a new one at a rental or a cabin. Plan tiers can cap the number of fences, such as 5 on Halo Bronze, and PawTronic saves up to six layouts.
Do GPS fences drift more than buried fences?
Yes. A buried wire does not move. A GPS boundary can shift by a few feet, more under trees and near buildings, which is why every GPS brand here asks for open space and a minimum yard size.
Is PetSafe the same company as Invisible Fence?
Both brands belong to Radio Systems Corporation, according to the copyright lines on their own websites. They sell different products and plans.
Which is cheaper, GPS or a buried fence?
GPS collars have public prices, from $199.99 to $999 for the device. Invisible Fence prices buried systems through a local consultation, so compare a written quote with the 3-year cost of a GPS collar, plan included.
