I'm looking into the PDA/software solution for rangecards. I've been looking at the info at maker's websites but still have some questions. Which program has the following options: Fully capable of metric units (meters, centimeters, Celsius, millibars or hectopascals. User can determine the size of click adjustments ( as in 1cm@100m) Calculated trajectory can be checked against reality. "Reality checks", that is live shots and the conditions, can be stored. Program can store and use multiple Vo/ temperature combinations. User can determine vital area and program will show range-window the calculated come-up is valid for. Program has the option of saving/using "BDC comeups". (Example: Ring marked 600m at click 50. Program could show calculation "600+2") Alternatively show MIL comeups.
