[QUOTE="Ridge Runner, post: 219834, member: 951"] ok, dumb country hick here, don't know if I do it right or not but here's how I do it I have a casio sea-pthfinder watch which after I press the button in 2 seconds it gives me station pressure (bar pressure where I'm standing) I enter this into exbal and enter zero for the altitude. My understanding of it is higher altitude lowers the bar pressure, which raises the bullets BC. this change in the BC is why altitude effects the bullets flight, so if you know your bar pressure, exbal compensates for it and altitude can be left at "0". if you put in a bar pressure reading and an altitude reading it over compensates, Is this correct?
