The purchase price to license this software is $149.95 and includes 1) the desktop support program and 2) the PDA field program. For complete information about each program prior to purchase, you may download the manuals for these programs. After purchase and verification of the credit card information, you will receive a License Key via email. (Please allow up to 48 hours for delivery of the License Key.)

U.S. Residents Only
If you live in the U.S., you may also purchase a backup CD which contains the program for an additional $25 which includes shipping via 2-day FedEx, if available to your location. Please note: No CDs will be shipped outside of the United States due to the prohibitive expense.

Nevada residents will be charged sales tax on the purchase.

Third - Activate the program with the license key.

Follow the installation instructions to complete the installation process. In order to activate the program, you will need to enter the License Key which was sent to you via email and the credit card information that you used to purchase the software. The credit card data is NOT saved on your computer, transmitted, or maintained in any other way, but is used solely to verify that the License Key is valid and the one that you purchased. Once the License Key is validated, the program will remove the time limitations. You will need to activate both the desktop and PDA programs.

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: The desktop version of 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. The PDA version has been "globalized" to accommodate both comma and decimal separators.

Important Notice: The desktop program is designed to run on Windows 2000 and above. The PDA program is designed to run on the Windows Mobile Operating System, Windows Mobile 2003 (including Windows Mobile 2003, Second Edition) and Windows Mobile 5.0. When you install the programs, you will need to .NET Framework 2.0 installed on your desktop and Microsoft's ActiveSync program installed (which should have been installed when you configured your PDA. At the commencement of program installation, have your PDA connected to your desktop. You may download any needed support software from this website.
