    Kestrel's Barometric pressure, do you need to "true" it each day of use?

    the most of the ballistic software accept absolute pressure or barometric pressure and altitude, the easy way is to use absolute pressure, to have this value in the baro screen in the Alt reference you have to put zero and you have always the absolute pressure, in this manner you can disregard...

    Did some testing of a solid today... @ 1k.

    supercrono is hard to setup downrange, only 1 degress of difference between actual inclination versus barrel inclination could give an error of 20 m/s, same thing for yaw error. good test !!

    Kestrel's Barometric pressure, do you need to "true" it each day of use?

    yes correct, the DA value from the kestrel is independent of what you set, so to take the number you can disregard either station pressure value or barometric pressure. but if you need to input these values in a PDA you have to use the correct numbers, to have station pressure put zero in the...
