When Netan put a bounty on SG-1, Odai Ventrell manage to locate Cameron Mitchell and Vala Mal Doran at Cameron's high school reunion. He first used the device to activate a personal shield when Vala tried to throw a fire extinguisher at him. When panic broke out at the reunion he used the device to magnetically lock all the doors to keep the guests as hostages. He then used it to communicate with the rest of SG-1 and demanded that they would beam down into the room. When the rest of SG-1 pretended to beam into the room Odai used the device to activate the Transportation rings on his Tel'tak to ring up his prisoners. (SG1: "Bounty")
