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.

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

Great activity monitor

I’ve found over all that Whistle has been most useful as an activity monitor, and not as accurate at tracking location. Recently the location just wouldn’t update, even though we were both in a strong cell signal zone. I talked to Whistle support, and they suggested updating the app. That didn’t seem to be the issue, as the app is working much better now that I’ve updated the operating system on my phone. I decided though to add an Apple air tag to her collar, which is giving me more security, especially since the battery lasts a year. I’m keeping the Whistle though, since it has some advantages, especially now that it’s working better: it notifies me when my dog leaves the safe Wifi home zone (the air tag doesn’t); it can be tracked by multiple users (the air tag can only connect to one device); and it gives me reports on her activity level. I wish the location tracking was as immediate and accurate as the air tag, and I wish they would outfit it with a long life watch battery, as it needs charging every day if you’re not connected to Wifi. The bottom line is also that my dog is so precious to me, I need two tracking devices to feel secure, but I do hope they continue to improve.
