TMR sticks: the end of drift, a generation beyond Hall
Drift — your character moving on its own — happens because classic sticks use potentiometers: a resistive track that wears down through friction. Hall effect solved that by reading a magnetic field with no physical contact. TMR goes one step further: it reads the same field with tunnel magnetoresistance sensors, which are more sensitive and draw less power. Translated: the same immunity to wear plus better resolution in the micro-movements, which is where aiming happens.
