- Submitted By Mark on 03/14/2019I 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 01/17/2019It 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.
- Submitted By Paul on 12/07/2018Never go hunting without it. My second-best friend after my dog.
- Submitted By Vincent Hunt on 11/15/2018My 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 10/17/2018I’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 06/22/2018Much, 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 04/12/2018Impossible 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.
