For non-penetration wreck diving, sure. A strobe for marking the ascent line. Clip it to the line high enough to be seen from anywhere within the range of visibility around it. It serves at least two purposes. In low-ish vis, it extends the distance from which you can see the ascent line (sometimes even double). If for some reason you and your teammate become separated (shouldn't happen, but ...), the first diver to the ascent line takes it with him so it also serves as an indicator that he/she has gone up (or you both can hang one, so there's always at least one light on the line). -- Art Greenberg artg@ec*.ne* -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
