A gravimetric scanner is a piece of technology which can be used to predict the outcome of dabo games.

Constable Odo, while stuck in his monoform shape, once saw a pair of Yridians using a gravimetric scanner to cheat in Quark's. As he was on the second level at the time, he instinctively leaped after them when they ran, intending to turn into a Tarkalean condor in mid-air. The constable was humiliated, despite Captain Sisko's supportive attitude. (DS9: "Nor the Battle to the Strong")
