A droid-like item used to survey resources on a planet. You plug in the survey tool of the type of resource you want to survey and then choose your desired planet. It will roam around the planet and will send a mail as soon as it gets a complete resource-list for the planet. The mail will not contain information about the resources' exact location, stats or concentration. Only the availability will be reported. You will have to look for the best place for your harvester or to sample your resources yourself by using your own survey device. This droid was added to the game with Publish 8.
