SportDOG TEK 2.0 vs Garmin Astro 320 & 430: Which Is Better?
This choice should be very simple.
If you want a tracking + training dog collar system – you’d consider the SportDOG TEK 2.0
If you want a tracking only dog collar system that is more advanced than the Astro 320 – you’d consider the Astro 430. But, SportDOG also does their TEK 2.0 tracking only model. Of the two, they are both good and have their own strengths and weaknesses, but we feel like the Astro 430 has a more detailed mapping system and tracking system than the SportDOG TEK 2.0 for more advanced and professional hunters and outside dog owners.
If you want a tracking only dog collar system that is a less advanced version of the Astro 430 or SportDOG TEK 2.0 Tracking Only Model, and has less features, consider the Astro 320
All you really have to consider is pricing.
You should know three other important things though, especially if you want some more choice or information in general:
