I check mine often when I am on stand. Early or cloudy will take the first setting but if the sun comes up, it will need another setting and as the day gets brighter you might have to go to 3 or 4 to see the dot. I never have the dot on when hunting. When I see a deer I will rotate the setting to what is needed for the light conditions. Batteries last a long time that way and some of mine are 5 years old. Target shooting has the light turned off a lot too when setting targets, etc. Even when walking the light is not on because it becomes second nature to rotate the switch for the light conditions if a shot appears. It is no different then cocking the hammer.
