Just a quick update. I took the FH10 out hunting foxes tonight... didn't get anything but the torch went great.
I was using the red light and had no problems seeing out to 150m on spot.
In close it was good to be able to widen the beam for a wider field of view.
I don't think I could go back to a white only torch with fixed width beam after using the Klarus FH10. Highly recommended so far.
