The Aether Analysis Device (usually just called the "Scanner") is a handheld device that detects spiritual energy in the immediate area and displays the results.
The Aether Analyzer resembles an early 21st century smartphone. When activated, the scanner will display a readout of the spiritual energy in the immediate area. Some customers have described it as a "spiritual geiger counter" in function. Most scanners include crystal fuses able to detect each type of spiritual energy , but some simpler models are made for one specific type. The scanner can experience interferrence from strong electromagnetic fields, but more expensive models tend to have shielding to prevent this. Some models can also be slaved to a computer or central scanner to provide an area map of spiritual energy.
Most scanners carry a battery life of 5-24 hours between charges for portable models.
