Nearly all digitizing tablets work with Didger. If you already have a tablet, Didger requires a 32-bit WinTab compliant digitizing tablet driver, available from most tablet manufactures (for no charge) or from third party vendors.

If you don't currently own a tablet, don't worry. You can digitize maps from scanned bitmap images.  With Didger's capabilities, large maps are easily digitized in a single project so smaller scanners or tablets work quite well.
