XXt-26 S-thread tracker

The XXt-26 S-thread tracker was a homing beacon manufactured by Neuro-Saav Technologies.

Technology
Its narrow-beam hyperspace transponder signal was configured to blend into the "background noise" caused by drive emissions, making it virtually undetectable except for dedicated scanners.

History
IG-88 hid two of these scanners aboard Boba Fett's Slave I and tracked the ship to Tatooine. IG-88 soght to steal the carbonite-encased Han Solo, but Fett outsmarted the assassin droid and claimed Jabba the Hutt's bounty on Solo.
