How accurate is the speed one? Has anyone got any real world figures to test? I'd try it but I have no idea how much my boat weighs

Seems to be an adaptation of the Harry Schoell formula, which is supposed to be reasonably accurate if you get the constant right for the hull design/weight etc.
So you almost need to test the boat to derive the constant, which kind of defeats the purpose really!

check out the link below, I put this onto my Iphone.
Nice little gps system and also gives you a speed reading. I don't think it's recommended as a main GPS but a nice backup.
The App is free to download then you pay about £27 for the local charts
Hope this might help some people.

Might as well go with Navionics then and have a fantastic system!
