Hi Badwolf, yes' ive been doing a couple of campaigns with the fleetboats, but the atlantic is where the heart is!
Anyway i'm thinking that for a couple of reasons it's only worth doing this watch for SH4UBM - one, speed of sound is only modelled in sh4, and without that the telemeter scale ahs no value at all, and secondly the SH4UBM chrono includes controllers for the minutes and hour hands of the clock while the SH3 stoppuhr is a stoppuhr only without being a clock too
thanks again Hitman
