Out here in the PNW we find ourselves at times doing night dives at 100' even when it's sunny and early in the afternoon. At this time of year the vis is great if it's more than 20'. Most of the folks that I dive with including myself always bring and use our can lights even on daylight dives.
Today I found myself diving with three other divers (all with can lights) and found myself enjoying the fact that I could easily keep track and tell what sort of dive they were having without having to look at them. By keeping track of their light beams I got all the info that I needed. My primary buddy's beam was always in my peripheral vision and when it wasn't I immediately looked for him. All the signaling we needed to do on this dive was done with our lights and was very easy.
It's not so easy when the water is clear and it's sunny, but for this type of diving these lights rule.
