Try OOM - for the money you don't spend on OCAD you can but field-worthy Andoid tablets and good GPS for mapping in the field. Or a lot of beer.
I think everyone here uses OCAD. I suspect BOK have a licence so Phil won't be spending his own money.
BOK (being the "biggest, best club in the UK"), has several licences. I will not be spending my own money. For "hobby" purposes I may use OOM for fun in the fields & houses around my new flat. And try to make a small map (for fun).
Nice to meet Mel today at Headless Hill Undy - she came over to chat to Jackie. I was quizzing Jackie deeply about her (also in Switzerland) full Achilles rupture she suffered a few years back (they operated the next day - total break).
Hurts just thinking about it.
