Rating: good light for holes
Reviewer: kurt w.,
the light feels good in the hand if a bit heavy. Took the light to Hawaii and lit up holes in the reef in bright sun light. I saw a lot more than I would have without it. You have to flip the switch back and forth to adjust the light level, separate settings on the switch would be much better. The narrow beam that lights up fish hiding in holes is not the greatest at night. It does cut through the murk. I will carry on every day dive and as a solid back up on night dives. The website stated I would get 2 batteries but only got one. Scuba.com stated Big Blue does not include 2 batteries and the website was incorrect. Not a big thing but I feel a little cheated.
