simple way to signal a distracted diver?

[The_blue]

A few weeks ago we dived in a quary that was pea soup, about 4m vis

We took a heading from a wrek to head to another and set off, within 2 kick my buddy was gone.....


she was above me venting air from her dry suit and as i looked around i couldn't see her 6-7m above so i had to start an accent to the surface.

She knew where i was and couldn't say untill i got the same depth as her and felt a tug on a fin.


What would be a good sound signal to use for something like this? she has a tank banger but it was on the tank mesh

was thinking of buying a rattle. any good?

Flipper pulling is good.

Or whack their tank with a solid object.

I've had divers ignore everything short of a hand grenade.

In these conditions, why not use a six foot line between you. Done all the time on "fresh" wrecks.

Bang your knife against your tank.....

Or buy the sub duck...don't know how good it works though. If a diver can't tell from which direction the noise is coming from, it does no good.

I've been wanting to try this.. hehe.. an air horn!

Probably a better thing do would be to figure out why she had a run away ascent (scary).

IID Lights work very well for signalling.

I doubt a noisemaker would have helped you that much in the situation you describe. It's hard to figure out the direction of a noise underwater, so you'd have known your buddy was around somewhere nearby, but it wouldn't help you locate him/her.

With my primary dive buddy, it's established who leads before we go down. I stay about 2 feet off his shoulder, always the same shoulder and stay there. Any problems, I grab his arm or vice-versa. Back before we set this in stone we had noise makers, but underwater in low viz they were really only for entertainment. We could honk out little patterns and repeat or vary them back to the other guy with a humorous twist. Or, we could just surface and get back to diving. We still have the noise makers, but they serve more to alert other divers.

We dove with a couple in Cayman that had the subducks. The sound travels fairly far, and after a few times it was surprising that you could get a general direction from them. It was at least enough to get us to look araound for them and try to see what they were looking at. Of course, in 100 ft viz, thats a lot easier.

Like mentioned in previous messages sound sucks in lowvis. Better to have a buddy line or/and light(spot or strobe).
