Ah ok, so I can go from x3 to the any one of the new sonar family, then once there can upgrade again to a fancier version if funds allow.
Also, if I go for the single time price rather than the subscription I get a year worth of updates as well as all the previous updates? If, after that year is up, there is an update that I like the look of I could start a subscription to get it?
Thanks again for your time!
