All varios have made huge improvements over the last 5 years or so. I can say the Clear Nav Vario is excellent when going from cruise to climb and especially on those broken chopped up thermal days and is much improved over the earlier Cambridge 302 vario which is now outdated technology. I also notice where as you would use either 1.7 sec audio to 2.3 sec needle with the Cambridge 302 you can use faster speeds in Clear Nav Vario and works well.
I can say I have used an earlier Tasman vario for past 10 years or so.
