Guys I just picked up exbal for the pc and a pocket pc and have a question about which data do you use when in the field. My data measurement device is a Brunton Summit ADC and the baro determines the alltitude. Do you put in the correct alltitude and the current pressure reading or the adjusted alltitude? This summer I had a chance to head to Colorado and the drop chart from home wasn't even close once I had chance to get out to 1000 to 1400 yards. My house range goes to 750 and the chart was very close to there but changed quickly after that. Thanks Dave
