SportDOG TEK 2.0
  • Submitted By Mark on 03/14/2019
    I initially started with TEK 1.0 and I am happy that this more updated version has a lot more to offer in terms of features and range. The setting up process takes a while and that user manual is super long, however, it's worth every penny even though my wife wouldn't necessarily agree.
  • Submitted By Kevin on 01/17/2019
    It took me a while to read the manual but, thank God that I did because I wouldn't be aware of all the things that TEK 2.0 can offer its users. I used it for the first time last weekend with my hunting buddies and although the range is not as high as it states, it was still good enough.

    Never go hunting without it. My second-best friend after my dog.

  • Submitted By Vincent Hunt on 11/15/2018
    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.
  • Submitted By Madison Spencer on 10/17/2018
    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.
