Jem'Hadar tricorder
The Jem'Hadar tricorder was a tricorder used by the Jem'Hadar soldiers of the Dominion.

In 2372, Temo'Zuma and Arak'Taral used tricorders to search for Miles O'Brien on Bopak III after he escaped from them. ()

The following year, the Jem'Hadar who accompanied Weyoun to Deep Space 9 detected the polaric particles from Elias Giger's cellular regeneration and entertainment chamber with their tricorders. ()
