We recently went on multiple night dives in Cozumel Mexico and used for of the lazer sticks. All four worked great. Our favorite was the blue. It was much different then everyone else and very easily seen from a distance. Our second favorite was the red flasher. So our next purchase will be the blue flasher. We were also happy with not wasting time, money, and the environment with chem sticks.
