Hi, Paul-- I have several different ballistic chronographs-- only one of the ones I have interfaces to a laptop (Oehler Ballistic Laboratory model).
There are inexpensive chronographs available for a little over $100. Some models do provide interface to a laptop as well as a LOT of built-in functions such as this one: http://www.midwayusa.com/product/773378/ced-millennium-2-chronograph-system CED Millennium 2 Chronograph System Over 1000 shot capacity with up to 500 string permanent memory Records velocities from 50 fps to 7,000 fps High, Low, Average, & Hi-Average velocity readings Extreme Spread & Standard Deviation Edit & Omit functions Built-in Calculator IPSC / IDPA Power Factor computation Function New Data Collector Software program included Meter or feet recording 10X Mode - records slower velocities in decimeters Voice Chip technology - Results can be heard as well as seen On / Off control, with no-memory loss "Auto-Shut Down" mode PC Downloads - USB interface for fast, software downloads of stored data Data Collector Software program included Low battery warning indicator Back-up battery storage Operating Temperature range (0°C to 50°C) ------------------ Mike Baker _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
