Underwater signaling device

[sytech]

I just purchased an "Acou-Stik" underwater rattle device.

Seems loud enough above water but it's way too big. It's 6" in length and about 1.75" in diameter.

I have a large gold ring on my finger that I've used to bang against my tank but it's not quite loud enough.

Any recommendations?

Thanks,

Sy

MARES has a shaker. Smaller in diameter. I have one when I assist in OW courses, to gain the attention of the student. Or in very low visability.

If your good at tinkering. Go to the home center and get some Stainless piping and two end cap and about 3-5 stainless steel ball bearings. That fit in the piping. You can make your own Clacker-shaker that way. Seal it and puch a few holes in it to drain the water.

OR a good light. If you and your buddy are in synic. a good light can be use for signaling.

A closer buddy?

I've tried a few different types of underwater noisemakers, but have always gone back to just banging the tank with the boltsnap on the lanyard of my dive light. If you don't have any gear with a suitable boltsnap, you could just hang a boltsnap or double-ender from a d-ring on your BCD.

I like my H₂YO Noisemaker. Fairly small, fairly loud.

You get bonus points for being the first person I've noticed that actually wrote H₂YO instead of H2YO. Even I don't bother with that detail most of the time!

At least among some SB respondents, one of those items that 'divers most regret buying later' is a UW noisemaker.

Agree. DIY is a good way to consider. You can also do this with simple PVC pipe. Learned it from a DM on Roatan, made one myself. You can seal it with cement, and NOT drill any holes if you want. You can use SS bearings or even get something as simple as small lead shot (SS is a little noisier, but not that much).

OR a good light. If you and your buddy are in synic. a good light can be use for signaling.

Very good suggestion. You and your buddy should practice, and agree on signals, to enhance understanding. My recent tec course experience suggest that lights can be great for signaling, BUT you have to practice (and practice) to make communication efficient.

Hi.
Try a tin clicker. Will last only a couple of dives and corrode, get them by the dozen for pennies. They look like this:

Very small, simple, fits in any pocket.

Or a piezoelectric kitchen gas sparker. Should really get attention.

here is a post that has a similar device, and would probably last longer ....

I use a clicker. You get them at Petsmart. They are used for training dogs. Cost a whole $1.49. Work great and you never see anyone else with one
