Im set to metric, and after a quick load to be sure, im setting the right dial. The dial goes all the way to '50', as someone in another thread mentioned, thats 200ft if thats '50' metres.
So from what i'm seeing, the setting to either metric or imperial, leaves the game torp depth seting in Imperial. Making the recognition manual worthless in metric. Kinda sad as reading things in imperial is like having someone speak to me in french, I have got no idea whats being said.
