Mark XI tricorder

Starfleet's Mark XI tricorder was introduced sometime before 2378. It largely did away with the antiquated button and toggle controls replacing these with a large touchscreen resulting in the tricorder resembling a PADD more than previous tricorders. Like previous versions, such as the TR-590, the Mark XI could be used to control starship systems such as force field controls, as well as various devices such as breaching charges and transport inhibitors, and has all of the previous versions scanning capabilities plus additional capabilities.

The Maquis discovered flaw with the TR-590 has been addressed with this model of tricorder and a high enough concentration of thoron particles no longer prevents credible readings.

Unlike previous models of tricorders the standard and medical editions are the same tricorder. The enhanced medical scanners of the Mark XI are built directly into the unit instead of being located in a hand scanner.
