All green laser products operating at 532nm are subject to varying degrees of illumination power loss in cold weather (60 degrees Fahrenheit or less) unless proper procedures are followed.
For optimal and maximum illumination in cold conditions:
1) Place 2 hand warmers around unit and secure with self adhering wrap which can be found in drug stores or camo color wraps in sporting goods stores. (The hand warmers slow down the heat loss through the aluminum housing).
2) Place a warm battery (room temperature) in the unit and turn on before going outside.
3) If the power level fluctuated, replace battery with a warm battery and continue use. (Rotate batteries as needed)."
