If your PRO L1 is not displaying any distances, even when focused on a pin/target, then it could be that the laser is in Speed Mode. When in Speed Mode the laser cannot locate a static target, only a moving target. You will be able to identify if you are in Speed Mode as the letters 'SPd' will be displayed underneath the sending laser symbol when looking through the eyepiece.
To change to either continuous scan mode or golf mode please press the 'M' mode button to change between modes. Click here for more information on the different PRO L1 modes.
If you are not in Speed mode and no distances are displayed then please contact us at email@example.com and a member of our support team will further assist you.
