    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.
  • Submitted By Tim Owens on 06/22/2018
    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.

    I bought this tracker specifically for the reason it is not limited to just USA. I travel a lot and take Bambie with me everywhere I go and I feel much safer knowing I can keep track on her when we are not together. She’s so used to us being together all the time that acts out when I leave her with the dog sitter and there were a few times she got away. Luckily I was notified right away since tracking doesn’t rely on cell networks. The first thing I did when I bought the tracker is set up her safe zone so I can keep an eye on her if she decides to look for me when I’m not there.

    The button tracking feature is just great because it shows you the arrow that moves in the direction of your pet. If you plan on roaming in the wild you should definitely turn it on in case your dog wonders somewhere. One other thing you can do is to build a safe zone around your dog and receive a notification if the dog leaves its safe space. The message will be sent quickly, maybe a minute. Both my boyfriend and I get alerts in case Simon runs away somewhere which happens a lot so we can tell you that this tracker really works.
  • Submitted By Fergus Kim on 02/01/2019
    This device is just a tracker and it does nothing for your dog’s activity. I don’t have a problem with any of its features tracking wise but I hoped that at least it will work as some kid fit beat machine. I can however monitor the distance my dog covers since it is reported avery few seconds. That way I could at least know how much miles Rita has covered that day. I one other thing they should do is make an app for your phone so you can track your dog more easily.

    Marco Polo dog tracker is what I would recommend to anyone who has an active pet or one that is not very well trained. In case your dog somehow gets away from you the tracker reports under a minute. Once you set a safe zone in which your dog usually resides the tracker will alert you if he or she gets out. You can react right away and not allow for anything bad to happen to your dog because its movement will update every few seconds.
