The D-Tector is the Digivice for the team of DigiDestines on Digimon Frontier. Each childs' Digivice has a different color sceme.  The new digivices are used throughout the season.

DIGIVOLVING INTO LEGENDARY WARRIORS

Using a digivice allows the kids to digivolve like digimon.  The D-Scanner scans the spirit's data during the Spirit Evolution process and changes the kids data to match allowing them to become digimon themselves.  When a digimon is defeated, the information is changed again into a fractal code and stored in the digivice.

SPIRITS

When a Digidestined finds a spirit, it is stored in the D-Tector for future use.

MAP

Finally, the digivice shows the digidestined where they are and where other digimon and friends are.
