"By projecting a focused harmonic beam into damaged materials, the repair tool channels construction nanites to return the targeted matter to its original state. Its on-board processor interfaces with a forward-facing sensor suite, instantly recognizing vehicles, devices, and personal armour based on microscopic manufacturer's tags. The beam, a bi-channel “hollow laser”, simultaneously acts as both a containment field and transport medium for the nanite swarm, which works to sift unwanted particles from the structure, undo ionization, and reconstruct the atomic patterns of the material.
The repair tool has several design innovations, the most surprising probably being the incorporation of Amarr focusing crystal technology. Beyond that, the device also makes use of an advanced K7 nano static co-processor on par with Caldari planet side missile tracking systems and a 55x5 reverse current power cell configuration rarely used beyond self-sustaining Gallente drone units. The result is an elegant tool combining the best technology from several very different design philosophies."
The Repair Tool is used to restore armour HP to injured units. When a target is fired on with the Repair Tool, they are locked onto, allowing the operator to look away from the target without stopping the healing process (but the process will be stopped if the target moves out of range, a static object comes in contact with the beam, or the target is Incapacitated. Repair Tools can also be used to repair armour damage to vehicles and installations.
Some more advanced Repair Tools are able to heal damage faster than certain types of weapon can output damage; making it a viable tactic to use the healing target as a "meat shield", while they terminate enemy targets; a tactic very popular to armour/omni tanking heavy infantry; who can mix this regeneration gain with their naturally high DPS potential.
Repair Tools cannot be used to revive an Incapacitated unit (Nanite Injectors are required to do this). It has an unlimited quantity of charge and repair nanites.
