Wonderful improvement!

The older pet tracker versions that Whistle offered were good, but the new Whistle 3 adds some well-thought-out improvements. The app is a bit more user-friendly, but the important improvements are in the device. It is smaller, lighter and more responsive than the older models. Plus, the home boundaries can be easily set in the app to match the property line - or any other dimension if you want. For me, this means that if my pet steps off the property I quickly get a notification. In my area, the coverage with AT&T is much better than the Verizon coverage on the old service and I get notifications much faster now. The notifications are more precise, too. They say my dog is “300 feet from home near 1234 Elm St.” I live in the city, so the faster, more precise notification could be a live saver. The only weakness, if I can call if that, is that when spending a great amount of time away from home (where battery power is saved by using WIFI), the battery life is less. But, Whistle notifies you when the battery is low and it can be recharged quickly while my dog naps. Last, but not least - Whistle support is wonderful. I have had their products for several years and they are helpful and very easy to deal with.

When it works its wonderful and a five star but when it doesnt it gives a false sense of security and rates a negative star to I’ll say two stars overall. Ive had several generations and have been using it for years. There will be stretches where it has been flawless with timely location updates and consistent results. Then there are the other times. One of those I appear to be in now. The app will alert me when my pet gets out of the Wi-Fi zone then will never be able to update his location again. I can load him in the truck with me now. Start tracking as soon as we drive down the street to the park, once there walk him on leash for the first twenty minutes and Whistle is constantly telling me it is having trouble locating him even though he is two feet from me. Same park/trial I have been going to for over twenty years and an area where Whistle has preformed flawlessly in the past. Now it spins looking for his location for over and hour but will tell me when we pull back into the driveway.

It was working perfectly last fall thru the beginning of this year then suddenly something changed and it is pretty much worthless now. Nothing has changed on my end with Wi-Fi or devices. I have contacted tech support multiple times in the past and they are very friendly but the advice is kind of all over the place.

When functioning its the best game in town I think but right now it’s incredibly frustrating and inconsistent.

Latest whistle hardware seems best

The whistle was the first reasonably priced GPS-based dog tracker that actually to the most part worked. Overtime somebody earlier versions location complains about being buggy and showing in accurate locations. I observe this sporadically but for the most part I did not interfere with the general use of the unit my earlier complaints were the health components such as the scratching an activity never seem to get enough data to give me any information and that seem to frustrate me and throughout all the time that I had it it’s gonna be a software issue more than anything else anyway that’s a big frustration with the earlier model was the battery not lasting more than a day and a half and having taking off the collar charging it and then I forgot to put it back on cash now going out.
Bottom line this newly designed unit with a dual batteries seems to be put together with some real thought it runs much better feels better than then you earlier models and lo and behold all of a sudden those areas that weren’t working before regarding activity scratching it supposed to be working now. I get them credit in designing a new unit that appear is quite sexy and seems to work very well I would actually recommended that’s far mind you I’ve only had it for a couple days
