The appearance of easily provable psionics has created some unique technology. Most of it was created to control psis in one form or another.
Detects the use of psionic powers up to 100 yards away. The psionic power shows up on a screen as a point plot. Batteries last for one hour. The device is the size of paperback book. This device is from Psi World Adventure, scenario 2, page 12 which is part of the basic rule set.
Prevents detection by psionic means of person carrying the device. The device is the size of a pack of cigarettes. Battery life is one hour. This device is from Psi World Adventure, scenario 2, page 12 which is part of the basic rule set. The protection range is my opinion since it is not mentioned in the rules.
A form of MRI and EEG machine. It can determine if a person is a psi or not a psi. It can also determine if a person has a spot on the wall power, minor power or major power. It can also occasionally determine what power(s) a person has. This machine is implied in the basic rules set. It is needed to seperate psis from non-psis. This is not portable. The early units were only installed in major hospitals and thus used only on suspected psis. It wasn't until much later that the machines got small enough and inexpensive enough to be in most police stations.
There are a number of psi drugs. Some boost psi powers and some dampen or block psi powers. The duration, dosage and side-effects depend upon the specific drugs.
