Garmin Alpha 100 vs Astro 320 vs Astro 430: Which Is Better?

The Astro 320 and 430 are tracking only handhelds, whereas the Alpha 100 is a tracking and training handheld. 

So, if you want the ability for training options – static, sound and vibration – go for the Alpha 100.

Apart from that, it depends what you want out of the handheld, and how many features you want.

The 320 has the least features, the 430 is in the middle, and the 100 is the most advanced/developed, and has the most features of the three.

For the tracking only handhelds, in our opinion the price difference is fairly negligible.

It’s probably worth just going with the Astro 430 and you’ll get extras like the TOPO U.S. 100K maps, Geofences, ‘Treed’ and ‘On Point’ notifications + more.
