  • Follow a compass which points in the direction the dog is going
  • Choose to see some, none, or all of your dogs on a zoom map
  • Send your dog’s control code to another handheld Garmin gear so they can also see and configure your dog’s collar
  • Identify the number of incidents when an “on point” or “treed” was shown
  • Count the coveys (groups of birds) and mark where you got a bird, where your vehicle or cabin is, and the trees or food waypoints etc.

Garmin Connect Is Highly-compatible Because:

  • If a T5 collar is being used, it gives you a range of 9 miles from collar receiver to the Astro 430.The T5 Mini, on the other hand, gives you 4 miles range.
  • It has a MURS frequency band.
  • You are given a free 1-year BirdsEye Satellite Imagery subscription which is well-matched with Garmin HuntView maps
  • Many of Garmin’s other devices are also compatible with the 430.


  • Has a tracking/GPS system only and not a training system
  • The handheld is costly
  • The additional collars are to be purchased separately and they are expensive too
  • You will have to check if the Garmin GPS data will work properly outside the US in case you are traveling. New Garmin Astro 900 will allow use in Canada.

The Garmin Astro 430 is overall a high-performing device apart from a few drawbacks given above.
