Not sure exactly what you mean by "adjust compass deviation". You first calibrate the compass by putting it in CAL mode and driving in two complete circles. You can then set the declination according to your location and display true north (as opposed to magnetic north). I don't know any accuracy specs but I'm sure this instrument works better than your typical auto compass. The compass can detect when it's off (because of an adjacent metal semi, bridge superstructure, etc.) and displays the word "Distortion". The display shows degrees as well as direction (N, ENE, NE, etc.). The altimeter shows only elevation, not barometric pressure. For accuracy you must calibrate it at a known elevation (like all altimeters except GPS). MM
