Are there different SkyTrak versions?

I'm looking to buy a used SkyTrak and would like to know if there are different versions. Thanks, Tom

I'm here looking for this same answer...are there any hardware variations over the years? I'm looking at picking up a used skytrak locally for about 1/2 of what a new retail one costs, but it was purchased in 2016 so its at least 6 years old...any users out there been with skytrak that long? Any degradation in performance or reason to buy new retail vs used for 1/2 price?

I could be mistaken but my understanding was that the partnership with Rapsodo ended fairly early in the device's life and since they were responsible for the hardware side of things, there haven't been any updates.
