I've read that the Deer don't see the Green or Red LED lights as much as say the regular white light so I have one of the LED head lights that have 2 settings of regular white lighting and 1 for the Red LED light becasue it doesn't shine at bright or get detected by the Deer as well.Sure...if You tromp around at night/early morning before daylight it can spook the Deer if they are close by but if You walk around with a bright flash light it will scare more Deer further off from where You are....say across an open field or woods that isn't very dense!Anything I can do to go un-detected I will try at least once to see if it works and so far each year I have gotten or seen nice Bucks where I hunt by being more cautious!
