If you wish to change the scale from meter to yards or vice versa, the procedure is pretty simple. You are supposed to switch on the rangefinder by pressing the power button. Once it is powered on, press the mode button that is denoted by M on your rangefinder. Once done so, you will find two options, "Y" and "M," on the top right side of the screen. From there, you can choose the Y option to convert the scale to yards and vice versa.
