[quote]: But now my question, how accurate can you actually measure range? (and from that calculate speed)? Placing marks on the icons on the map is easy and deadly exact, but what steps does the line tool allow you to see? 50 Yards, or tenths of a nautical mile. And doesn't sonar give you noisy readings? Compare that to your average merchant ship movement at 10 knots in 30 seconds. Don't you think you should give it some more time to move it's butt and get it accurate? (if the ruler showed 100yds or 200 yds, what would your speed calculation say)
I'll say again that I have great success by timeing how long the target takes to cross the 0 bearing line of the scope, and useing it's length to determine speed. There are several lists out there that have the lengths of the in game ships, not to mention the fact that the poster of target ships that came with the box version of the game also lists the lengths. No fuss, no muss, no estimating. Works every time
