The Ha'tak control panel, also known as a Ha'tak hand controller, was a computer system used by the Goa'uld.
These control panels were located at the Pel'tak of a Goa'uld ship such as a Ha'tak vessel. They appeared as large table shaped machines located at the front of the bridge. When activated, two large pillars rose from the side and a reddish panel emerged in the middle. From here, a user was capable of manipulating the vessel.
Klorel onboard his Ha'tak activated the controller in order to raise his ships shield to protect it from the Goa'uld-buster weapons launched from Earth. He was in the process of activating it when his host Skaara began resisting him which almost prevented him from accomplishing the task. (SG1: "The Serpent's Lair")
