Built for 6 or 7 pin systems, however, less can be achieved by using a decimal to erase a chamber.Minimum of a control and master key are required to make a chart. Additional change key available for all devices; 2 change keys available for 4" screen devices.Randomize function will generate completely random charts each time it is triggered."Lock/Unlock" toggle disables/enables all inputs and functions to prevent unwanted/lost changes.Control Finder is an added bonus by reverse engineering a core to determine the control key's bitting.

There are two methods for achieving the control key: 1. using the master, control, and bottom pins, or 2. using only the top/driver pins.Up to 16 different projects can be saved at any one given time.All projects are encrypted and protected with a passcode.AirPrint or Email projects with a single tap.
