For marker lights I think it's annoying to other divers to wear a flashing one. Stick with constant on.reefugee:I was wondering - what would be the best color to use? I was thinking about a flashing red one. And then I was going to get my fiancee a green one, and me a orange one. That we we can distinguish ourself from other divers. What color is the most visible underwater?
If you are night diving regularly with other people you know in close quarters for some reason, then maybe it would be useful to have different colors to tell who is who. Otherwise you may as well just get 2 of the same color, gives some indication you're a team, which is arguably more useful than other people being able to tell you apart. A bunch of strangers on a boat really aren't going to memorize everybody elses marker light colors. You don't know what other people might have anyway.
I'd avoid the yoke lights, nice idea in theory but they flood way too easily.
Even if the sticks aren't toxic, when used on land they will at least most likely get thrown in the trash. When used diving I think the fear is they may wind up in the water and something will try and eat them. Even if the stuff inside isn't harmful the case isn't so good for any critter.
