All equipment here, more-or-less describes a family of equipment. If the Jedi Order has the equipment available to them, they will have a specific instance in stock. For example, they might have a Rakor-T4 Tracking Beacon, which is a specific type and make of Tracking Beacon. Sometimes two pieces of equipment from the same family might offer different slightly benefits.
Some of these equipment types describes a very broad family of equipment instead of a ready-as-is equipment. This means that the specific instance of that kind of equipment must be designed and approved—if this is the case, it is noted on that equipment type's page.
