I use 2 decommissioned iphones as simple in-the-field PDA's with Ballistic AE installed. I take an accurate atmosphere, Input the data into Ballistic and output a drop and wind chart on the phone. All that needs to be done at this point is to lock the screen and put the damn thing in your pocket. If need arises for a long range shot, normally you'll have plenty of time to range the target and refer to the output for extremely accurate data. Opening the locked screen is as quick and simple as looking at data on your rifle.
Rick,
Using the de-com iPhones is a clever method. And you use the watch to change data in the app if a front comes in? What are you using for back-up if the battery dies, device failure, etc?
Also, for most medium-range hunting out to 500-600y, standard atmospheric pressure works really well under most conditions, right? Unless there is a record storm the differences will not be worth making changes for on deer and elk. If you are changing elevation, then new data is needed for that elevation... but using standard pressure.
Now one could say that animals are more likely to move with large swings in pressure, but unless there is a huge storm coming the change in pressure isn't worth correcting for. Longer ranges is a different story.
