Great for sporting dogs
Is best compatible with the T5 or T5 Mini collars
Also compatible with the TT15 collars, but you can’t use the training functions because the Astro 320 is not designed for training
You can track up to 10 dogs at a time from the 320 handheld, which means you can have up to 10 total collar devices connected to it
With the T5 you’ll get 9 miles range from the collar to the handheld, and with the T5 mini you’ll get 4 miles
The physical dimensions of the 320 are 2.4″ x 6.3″ x 1.4″
It weighs 9.2 oz with the batteries
The 320 comes with a preloaded worldwide basemap – there’s also optional BirdsEye Satellite Imagery and TOPO maps

A tracking system only – no ability to train or use correction cues with it like static, vibration, and sound
For the price, it’s worth considering the Astro 430, or even the Alpha 100 – both of which have more features
