How to calculate ACCURATE range without having to use the stadimeter?

[Hitman]

Using the WO to give you reports every 3m.15s seems a great and easy way to get the plots needed (with god mode off) .Is he fairly accurate then,and are his reports to be relied upon?

He does round up the values to the next hundreths, i.e. 5634 metres is 5600 metres, but that is not just close enough, but also realistic for what you would expect when using a small hand-held rangefinder (In fact may be even more at long distances) and is good enough for plotting while surfaced. Once you are underwater, at periscope depth, it will be just you who can look through the periscope and construct the firing solution -again realistically-

I have seen copies of the UBCH on Amazon,and it is extremely rare to get hold of,do you know any other places that might sell it?,ideally UK suppliers.But if it can only be ordered overseas I may have to open a paypal account,something i'm not too thrilled about doing...still
