HEY! Attention OVER HERE!

By mamashark

This is the best thing ever invented! I love it! Get's attention right away. Wouldn't leave the boat without it!

The Acou-Stick Underwater Noise Maker is patented technology used by divers, Dive Masters, and Scuba instructors worldwide. Get your dive buddy's attention fast and easily--just a simple shake sends sound up to 100' (30m)! No batteries or maintenance required! Unlike simple "rattling" devices, the Acou-Stick Professional Underwater Communicator stays silent while swimming and when stowed in dive gear or luggage. It only works when you want it to!

This virtually indestructible device is constructed from high impact, high strength polymer for years of maintenance-free use. Acou-Stick is compact; at only 6" (15.24cm) long, it will fit easily in to your BCD pocket, making it handy when you need it. Acou-Stick comes equipped with a 12" (30.5cm) nylon wrist strap. If you do happen to drop the Acou-Stick, the high visibility fluorescent green color will make it easy to locate. The Acou-Stick is near neutrally buoyant for ease of carrying, and it is proudly made in the USA.

not so bad

By Pol

Napoleon fish really like it!! Specially this white looks like eggs tips. :) I fasten it to my bcd, and it become entangled everytime you dont wear it. It's really too big. You can listen it about 10 meters far away.


UnderWater attention getter...

By Mermaidinme

Great for getting someone's attention while underwater... Very similar to the "homemade" ones that I've seen, however, this particular one is much larger than I expected... Which makes it someone heavy and slightly ackward...


Just so-so

By Diver D.

Bought this for my daughter, but it is so cumbersome that it gets in her way when hanging on her BC, and is too large to comfortably fit in a pocket.

Good but large

By Cro

ok i admit that this noiser is better than other with the noise range range, however the size of it is just too large and it could be annoying while diving on the other hand the weight is too heavy compared to others. right now im using Mares noise maker its very thin , small size and does good noise and it can bring everyone attentions.


Acou-stick - not worth it !

By Karen

This was a complete waste of my money! If it wasn't so much trouble sending it back I would have but I didn't have the time nor inclination to bother. I took it out once, shook it right next to my husband's head and he coudl barely hear it. It would never attract his attention if I ever needed him in an emergency!


Questions & Answers

Questions about this item:

Shopper  Why Did You Choose This?
SYDNEY Y  I have had this in the past. It is a great underwater signaling device. I gave away the last one I owned so needed to replace.
LAURA P  This is my favorite noise maker. Inexperienced people use a knife as a noise maker. What happens if you drop your knife and its too deep to go get? This is also less stressful, easier to make a compelling noise with this instrument. I recommend this particular model to all my scuba clients. Laura at Private Scuba Lessons dot com
JAMES R  Because it works well, is small, and not metalic in its design. JR
KEITH H  not loud enough! and a little too big for my needs. returned ... but it did work!
Shopper  What sound does the acou-stick make?
GREGORY K  We call it a "clacker." The harder you shake it, the louder it clacks, like a ball bearing in a heavy plastic tube (?). It cannot compete with an air horn as an attention getter, but if your buddy pays attention and isn't too far away, it works fine.
SEAN N  It makes a clunking noise. I think it is a slug of metal that slides back and forth. Very distinct noise under water. I have it on every dive.
SYDNEY Y  TOck, tock, tock, tock. I love it! I have given mineaway to dive masters all around the Caribbean!
