|Mask of Detection|
|Power(s)||Detects hidden beings and the Ignika|
|Notable Wearer(s)||Hahli (fomerly)|
The Kanohi Elda was the Mask of Detection. It granted its user the ability to sense the presence of any nearby hidden beings, such as a Huna or Iden-bearer, and allowed them to track the Kanohi Ignika through increasingly strong headaches. For this reason the Kanohi Elda was a somewhat rare Kanohi because its primary purpose was to locate the Ignika.
Kanohi Elda were always on at a low level.
The only difference between the Great and Noble Elda was that the Noble only allowed the user to see hidden beings.
