Garmin Astro 430
  • Submitted By Leah Thomas on 11/27/2019
    Before I bought the Garmin 320 I read somewhere in the reviews that there is a rescue mode option that allows you to save the battery by switching to it and that feature enables you to save the battery life when it’s on its end and track you dog for a few hours more. It also has a highly advanced map tracking options that allows you to update maps depending on taking the road or going through water and stuff like that. It’s a really professional device because it offers so much more than a regular map which you get with a regular pet tracker and you can also store detailed information about each time you catch something like place, time and that sort of stuff.

    Apart from being expensive I can’t seem to find anything wrong with this tracker. My wife bought it for me as a birthday present, I think she likes to see me out of the house honestly, and it really did the trick. The only thing I think needs improving is the battery which could be a bit more long lasting but you can recharge it over night. The range is impressive, almost 10 miles with gps being wildly accurate at all times. There is no glitches or bugs, the tracker is fast and precise and what I like the most is that you can adjust the display to show you important information without having to stop and look for it yourself.

    This is a durable device built to withstand everything you can possibly thing off. My dog and I had some crazy adventures and let me tell you I didn’t think it would last. I’m sorry to see the company disconnected the line but I truly hope the new version is as good as this one. I can not tell you how many times the bright orange collar helped me spot Max and stopped me from making noise and ruining a perfectly good shot. I really do thing that is worth every penny and you can see that is is built to last. The performances are excellent including the gps which is crazy spot on.

    I’m a passionate hunter so a friend recommended Garmin. It was a bit pricey but I did my research and read tons of reviews and finally decided to invest. The company has such a good reputation which has proven to be a deciding factor. It everything proofed, long range and I can transfer all the data via usb. The battery, however, needs some improvement considering it is a regular aa battery and the life span is not too long. The same goes for the rechargeable battery which only lasts for 40 hours max and my hunting trips sometimes last for 3, or 4 days straight in complete isolation. I suggest improving that otherwise everything else is great!

    I’ve noticed that it doesn’t work very good once it’s not within our home’s wifi zone. Sometimes we go camping and there’s almost no cell reception there so we have problems receiving any data at all. But when we are at home the thing works perfectly. It’s fast and accurate and charge it one a week. Once Stella ran away from my daughter when she saw the neighbours can and my daughter didn’t manage to come home and tell us that for about 5 minutes but I already knew since I got notified and we found stella exactly where the app pinpointed the location within a few minutes standing under the tree, barking at the cat.

    Tracy used to wander away from our yard and end up in our neighbour’s yard playing with their dog so to be able to track her down and immediately get notified when she escapes is what matters the most. With whistle I can set up a perimiter where she’s allowed to go and get notified once she leaves that space. It saves me lots of time and worrying when she leaves the yard and when I’m not home I just text the resto of the family where to pick her up.
  • Submitted By Jenna Simmons on 05/07/2019
    I love that this app works as any other activity app I use. You simply download it to your phone and use it like any other where you get to see the history and set up goals once you enter your dog’s information. I share Donna’s activity date with my husband so we can know how much exercise she has that day and dont overdo it.
  • Submitted By Patric Small on 04/05/2019
    This was my tracker of choice because it functions as both tracker and activity monitor. As a family we are passionate hikers so being able to track our Tom’s vitals is very important to us especially since he’s an older dog. The thing I also like is that you have constant coverage because is connected with you phone all you need to do is download the app. You can connect through bluetooth and use your home’s wifi. The cell network is AT&T and if you don’t have wifi you can track your dog as long as the area is covered by the network. And when the signal is strong the coverage precision is really good. We didn’t go anywhere so far were the signal isn’t strong so I don’t know how it works in those places.
