Im building a cosine angle indicator and am wondering how many significant digits I should use for long range. I notice that the ACI only uses 2 digits and I just captured a pic from the back of a Suunto angle indicator and they use 4 digits. Any body play with more than 2 digits for long range?
5degrees off of level: ACI .99 Suunto .9962
15 .96 .9659
25 .91 .9063
Looks like they only differ by about 4 yards or so out to 1000.
