Garmin Astro 430

    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!

    My two dogs simply love roaming around my 50-acre farm as well as the surrounding area and Astro 320 tracks them over the whole property without a hitch. Now, I can simply press the button on the device attached to the collar and let them run to their heart’s content.

    I’m a passionate hunter and just had to buy this tracker once I saw my friend using the 220. It’s really easy to track my dogs now even when we’re in a wooded area. However it doesn’t work for me when I plug it into my car and it charges very slowly when not connected to the power socket in my house.

    Much, much better than Astro 220, the maps are awesome, it may be expensive but any hunter can tell you that it's more than worth the cash.
  • Submitted By Rob Walker on 04/12/2018
    Impossible to list all the reasons why Astro 320 is the best dog tracker I've ever used, you simply have to try it yourself. I first tried my pal's Astro and I was just blown away, ordered it the same day, been using it for more than half a year, not a single glitch and I'm loving it more every time I use it.
