Holosun HS403C Solar Red Dot

  • Based on the already successful Paralow  HS403A Red Dot, we have released a solar powered version, the HS403C. This new product has two power systems, one is operated by solar power only while the other operates on battery only.  Out of the box, this red dot is automatically solar powered.  The red dot intensity also auto adjusts to ambient light.  If there is not enough light, such as at night, just press the "+" or "-" button to activate battery power.   Now it will operate like a regular red dot such as the HS403A.  You can adjust the intensity by pressing "+" or "-" buttons.

    The unit is now automatically in solar powered mode, ready when you need it.   You can verify the power mode by covering the solar cell.  If the red dot is on, you are in battery mode.  If it is off, you are in solar mode.
