The Garmin Astro 430 is the new Australian Legal Garmin GPS and GLONASS tracking system to replace the Astro 320 unit which has never been officially released in the Australian Market. It can track up to 20 dogs at a range of up to 7km. With a 2.5 second update rate that is twice as fast as its predecessor. So, it is quicker to pinpoint the location when dogs are on the run. Intuitive and easy to use, the Astro 430 features a vibrant 2.6 inch display, preloaded TOPO lite Australia map and an optional in-unit rechargeable battery. Also includes Hunt Metrics dog performance data to help analyse your dog’s tracking patterns and behaviours, so you can train more effectively.

Astro 430 vs previous Astro 320, 220

The new Astro 430 has faster 2.5 seconds update rate. It can also track up to 20 dogs where Astro 320 and 220 can only track up to 10 dogs. Astro 430 works with Garmin T5X collar which is a better collar than the DC series tracking collar. Astro 430 has built in wireless share feature which is compatible with DriveTrack 70 LMT Car GPS and Fenix 3 watch. It means you can track your dog with a 7 inch big screen in the car as well as a convenient small watch while out in the field.

Astro 430 vs Alpha 100

The Astro 430 looks like a tracking only version of the Alpha 100. It has most features of the Alpha 100. The main difference is the Alpha 100 has touch screen and Astro 430 offers back to basic keys operation for different users. The Astro 430 will have a longer range than Alpha 100 because it doesn’t have the training module that requires it to communicate with the collar. With only one way transmission, the Astro 430 is equipped with a longer antenna than the standard Alpha 100 handheld.

Please note: the new Australia version Garmin Astro 430 will not work with any previous Garmin Astro handhelds and DC collars.
