ChairGun Pro Desktop / Laptop Version
(Windows / Mac OS X)

For those who wish to delve a little deeper into airgun or rim-fire ballistics, we present ChairGun Pro. Based on the highly successful ChairGun2 and 3, the interface has now been redesigned to make it more intuitive and easier to use. ChairGun Pro uses modern, accurate ‘modified point-mass’ ballistic functions to instantly give you the essential data that you need.

ChairGun Pro is a free tool designed to compliment the Hawke Specialized Reticles (SR6, SR12, SR Pro and Deer PASS SR), the Hawke Multiple Aim Point reticles (MAP6, MAP8 and Deer PASS MAP), the Hawke 1/2 Mil-dot Reticles (10x and 20x) as well as traditional generic Mil-Dot and 30/30 reticles.

Take the information into the field - ChairGun Pro allows you to print trajectory graphs, tables, reticle images and range finding calculations - and save settings for future reference.

And it doesn't end there . the supplied pellet database is comprehensive, editable, printable and can be updated on-line. Additional 'helper' programs are included for specialized tasks (such as PCP Bottle Filling, Range Cards, Scope Tapes or Maximum Range and Crosswind analysis). The set-up package also includes a comprehensive help-file and access to on-line help

ChairGun Pro's modern ballistics functions have been thoroughly field-tested. If your requirements are simple or complex, the graphs, tables and labels give accurate information that would take hours of tedious range-work to achieve manually. Perhaps you're wondering how a different pellet will affect the trajectory of your airgun or a change of calibre or scope or mount height.
