A GPS pet tracker can save your cat’s or dog’s life if it ever escapes home. After spending more than 25 hours researching and testing four trackers, including having Wirecutter staffers take them all on a trip around Manhattan and a 35-mile bike ride, we’ve found the Whistle 3 GPS Pet Tracker & Activity Monitor to be the best tracker for most pet owners. Not only is the Whistle 3 as quick and accurate at tracking as any other model we tested, but it also has the longest-lasting battery by far.
Who this is for
A GPS pet tracker, like most emergency gear, is something you hope you never have to use. The device uses an embedded GPS transponder as well as cellular data signals to communicate your pet’s location at a given time. The idea is that if your pet escapes, you’ll receive a notification via an app, have the ability to track its location in real time, and be safely reunited.
How we picked and tested
To track accuracy, we sent the trackers on a 35-mile bike ride in upstate New York, periodically checking the trackers’ status and reported location. We also visited five locations in Manhattan to test both how accurate each tracker’s reported locations were and how quickly each tracker’s companion smartphone app updated. To read more about our test procedures, please see our full guide.
Our pick
Throughout our tests, we were able to get the Whistle 3’s location in a matter of seconds, and that reported location was always close enough to the actual location that we’d be able to find our pet easily. We like that the Whistle 3’s smartphone app shows you not only where the tracker is but also where you are in relation to it, which is handy if you’re trying to find your pet in an unfamiliar area. The app also has a button to refresh the location manually, something other trackers’ apps lack.
Where the Whistle 3 most sets itself apart from other models is in battery life. When left undisturbed inside a home Wi-Fi safe zone, it didn’t just last longer than any other tracker—it even surpassed the amount of time we allotted for the test. Thirteen days into the test, and six days after the next-longest battery gave out, the Whistle 3’s battery was still at 69 percent.
The Whistle 3 won’t come off unless you hold down a spring-loaded button and twist a quarter turn, an action your opposable-thumb-lacking companion is unlikely to purposefully or accidentally take. The Whistle 3 is also rated IP67, meaning it’s dust-tight and can survive being immersed in up to a meter of water.
Like most competing trackers, the Whistle 3 requires a 3G service plan. You can choose to pay $ 10 a month with no commitment, or save by paying for a year ($ 100) or even two ($ 170) in advance.
Runner-up
Vaguely shaped like a bow tie, the Paby tracker is small enough that it fits on most dog or cat collars, attaching with a strong band. You have to use a tiny screwdriver to replace the band if it ever breaks, but the tool is included in the box. And by “box,” we mean the collapsible water bowl the tracker comes packaged in—a very cool and wholly practical design choice.
The Paby’s charger is its biggest failure. The magnetic pad has an extremely weak magnet, and it rests right up against the aforementioned rubber band, so the charger can too easily pop off, resulting in an uncharged tracker. That’s especially a problem with this tracker because it has pretty poor battery life: It lasted only four days in our safe-zone test, and was down to 53 percent at the end of our bike-ride test.
