[QUOTE="ptosis, post: 2031716, member: 116258"] Awesome! Thanks for thinking about me! The SIG Kilo device measures should be just fine; it is purpose-built for shooting, so it does not confuse the user and shows honest station pressure. It does not even have an altitude input. (And to answer your second question for the sake of completeness -- yes, it is possible to deduce the actual station pressure back from the "sea-level reduced", but we would need to know the altitude value which the device "thinks" it is at. In my experience with Kestrels, the process would be very prone to error, as the device tries to track altitude for mountaneering and aviation applciations, and tends to "drift off" when pressure changes.) And yes -- the data would be very very useful for me. I am not actually using the 5 distances that Labradar shows data at. Especially since the further it goes, the less reliable information is. What the calculator actually uses is the raw track files -- measure of speed and distance taken every millisecond. Labradar writes these to the SD card (and maybe also temporarily stores them in internal memory). You can get them from the smart card or through the USB cable (Labradar itself then appears as external USB storage in the computer). I would very much appreciate if you could recover these tracks for me. Hornady will be a very welcome addition to the testing set; I mostly shoot Swiss ordnance and Lapua. Thanks again! Cheers, P.
