The precise view visibility threshold value can be modified by pressing long on the bottom-right navigation button and selecting the *Precise View Settings* menu item.
The precise view will turn green when the current location is considered to have hit the target. This state considers both the positioning device accuracy as well as the precise view threshold value, whereas QField will consider having hit the target when the distance between the current location and the destination *minus* the positioning device's accuracy is less than 1/10th of the precise view threshold. E.g.: if your precise view threshold is set to 1 meter and your positioning device accuracy is 0.05 meter, the view would turn green when the position is less than 15cm from the destination.
