Exbal for Handheld Devices

Attention Pocket PC Phone users: While we have not advertised Exbal for Pocket PC Phone devices we have had reports from several users who have successfully installed the Pocket PC version of Exbal on Pocket PC Phone devices running the Windows Mobile 5.x OS or later. See the new white paper which discusses the difference between Smart Phones and Pocket PC Phones. SmartPhone.pdf

Attention for Palm Users: We have had users report installing the Palm version of Exbal on Palm Treo devices running the Palm OS.

For Users who do not have a PDA yet: For users who are trying to decide on use of a Palm vs Pocket PC we recommend the Pocket PC. It is based on the traditional Microsoft Windows platform so its user interface is familiar to most users. Microsoft is continually adding new features to the Windows Mobile OS.

Exbal is available on the Palm Pilot. Take it to the field and recalculate the ballistics to match your environment. Exbal for Palm hand held devices uses the same rigorous ballistic motion equations that are used on the PC version. Like the PC version, the Palm version is very efficient and does not require much memory (approximately 40K). It has been validated on Palm OS 3.1, 3.5, 4.0 and 5.2 using systems with at least 1 MB of memory. (see Exbal Features for details)

Palm units with a memory card can take advantage of a backup program that is available at www.jkware.com
