Good day folks, First let me state that I've no association with PolarView other than being a VERY satisfied consumer. This thing is the nuts, truly. It's MUCH more intuitive than the others I've tried and they are many. I suppose I've tried just about every shareware, free, demo version of software out there. I have an issue with popping for $300 or so for such a piece (I know, I know) but with PolarView having a free trial version I gave it a shot. I like it so much I bought it. It's really a neat piece of software. Give it a shot and see what you think. I hope this helps someone cut their search short. Jim (S/V Two Can) 78 Cherubini 30
