Important Notice:  During the evaluation period you will have the opportunity to determine whether this software meets your requirements.  We urge you to take the following steps to insure your complete satisfaction with the product:  1) calibrate your scope; 2) obtain a good muzzle velocity for the bullet of interest; 3) precisely measure the atmospheric variables of pressure, temperature and humidity; and, 4) calculate a DK for the bullet of choice.  If you have taken the time to complete this work and do not find the program accurately calculates the actual trajectory of the bullet, you will, of course, not wish to purchase a license.  We would like to hear from you if you decide that the software did not meet your expectations.  We are anxious to learn of user experiences, suggestions, or complaints.  We appreciate the time and effort expended in learning and evaluating this software.
 
Important Notice:  This software is currently designed for use in English speaking countries, such as the U.S., England, Australia and other countries that use the decimal as the separator in decimal numbers.  (Example: 12.3456)  We do not recommend installation of our software on computers that  use a comma or other separator (such as Germany or Spain where the separator is a comma.)  (Example: 12,3456)  While the software can be made to work in the "comma cultures", the workarounds are not obvious and not supported.
