[QUOTE="985, post: 214347"] When using the Kestrel Units to obtain the "Station" Barometric Pressure, the reference altitude must be set at 0 Feet. This will give you the "Station Pressure," which is what you want. To obtain altitude, you must set the BP reference to a known altitude for the current weather system. This is good for mountain climbers, as they may need to know what elevation they are at, although for Shooters utilizing Night Force Ballistic Targeting software, it is theoretically irrelevant. HOWEVER, you can use a combination of the altitude and the BP to obtain an even greater percentage (although very small) of accuracy. This is how it is done; 1. Obtain an altitude reading from your GPS and enter it into the data entry point in your NF software. 2. Make certain that you check the "Use Standard Pressure" pick-box 3. Pick the "Calculate" button. 4. Re-Run the calculation again, but first uncheck the "Use Standard Pressure" pick box and enter your current BP "Station Pressure." 5. Pick the calculate button again.
