I love night diving. Turns up the adrenalin, I found I am slower, look around more. I love stirring up the water to see what lights up. On the quarry dives we would shine the light on the very small

and the very big

would thank us for the meal (the circle of life) or light in this case.
In the daytime, I like to go out early with good light for pictures. But given the case I would choose the night dive every time.
