    I'm curious to hear about how people have "designed" their own underwater noise makers. Tell us about contraptions that you use to signal other divers underwater.

    I once saw this guy with a whole string of carabiners that he rattled underwater. Sounded like Santa Claus was coming to town but was a bit bulky to carry around and dragged along the floor.

    I'm also thinking about getting a subduck, but my sea-quest airsource is pretty difficult to keep in my mouth as it is without adding more equipment to the inflator hose, making the whole thing a lot stiffer.

    Never really cared for tank bangers that are a pain to change from tank to tank.

    I've always dreamed about some cool and easy to carry and use device but one head can only come up with so many ideas!

    Nearly purchased a very expensive Rattle with MARES stamped on the side. It retailed at £25.00GBP.
    So being a resourcful chap I went home raided the shed forn a 6inch length of 15mm copper tube, filled it with some 10mm ball bearings, soldered two endcaps on it and voila, one home made noncorrosive rattle - 's bleedin loud 'n all

    The subduck is an interesting device. Have you ever used one? I can get them, but I've never seen one in real life. I get a lot of requests from Europe for them, but I haven't figured out a cheap way to ship over there. If you get one let me know how you like it.

    My knife against my steel tank seems to work just fine. On a side note, I am going to be trying something new on my next trip. I was at the LDS the other day and some guy was in there. He was trying to sell his product. It was an underwater fish call. He gave me and my buddy about 30 samples to try. It is basically a straw filled with bb's. It ain't that loud, but he said it attracted fish, and could be heard underwater. :shark:

    Check out the wreckmania threads (I think #2 or 3) in there, Walter and another member talk about "building" a rattler. It sounds pretty simple if you have the stuff.

    Is the "Subduck" the same device as the "Hammerhead?" I ask because the "Hammerhead" makes a sound that I usually describe as a quack. By the way, I think the "Hammerhead" works very well.

    SubDuck is the larger version of the Hammerhead.

    I wonder if the Warhammer would be a good way to generate noise underwater ?

    That depends on what (who?) you hit with it. ;)

    Make sure it is between your buddies inhalation and exhalation....

    My SeaStorm whisle works underwater, and you don't need another piece of gear.

    I hate to be a party pooper, but why not leave the noisemakers behind?

    I've heard the Subduck underwater. Sounds more like a mid-pitched "eeeeee" buzz. Almost like the perceived sound when you get a mild electrical shock.

    One thing to remember when using such devices is how sound travels underwater, as well as the distance.

    When I heard the "ducks", I swear there were two of them on the complete otherside of the quarry and they were playing their version of the poolside passtime, "Marco Polo".

    I found it kinda annoying after a time.

    One technique I have read about (and want to try) is cupping your hands to form an air bubble around your regulator and then yelling through your reg. From what the article/post said, if your successful, you can generate a pretty lound sound and quite possibly intelligent speach. (well, just speach when dealing with NetDoc and Iggie D)

    A "Hammerhead" can be truely annoying if it is used as: "Quack, Quack. . . look at this fish"- - -"Quack, Quack. . . look at this other fish."

    We rarely use our "Hammerheads," and when my wife uses hers, it means: "Quack, Quack. . .there is a Bull Shark looking at your stringer."

    I don't endorse "Hammerheads" as a shark defense, but I have seen Bull Sharks turn tail when they hear it.

    How well do those work underwater? I just got a "windstorm" (the smaller version) and noticed that it said it worked under water but I haven't had a chance to try it out yet. I did blow into it in the house and it is the loudest thing I've ever had that close to my head. :dj:

    Yeah, I've seen instructors punch an open palm with a fist and it seems to travel a fair distance. Never got the hang of it myself though. need...more...macho... Anybody know what's the correct technique? (e.g. which part of the palm to punch, how to form the fist, which part of the fist to use, etc.)

    Yeah, I saw my instructor do this, and thought it was a cool enough idea to figure out.

    lessee... closed right fist. Not too tight (like you're about to punch), but solid. Actually, a sign language 'e' is extremely close.

    Bring your left palm heel so that it strikes the first joint of your right index finger, with a good mass of the heel covering the hole made.

    You can practice out of water, it really isn't hard. But I've heard a SeaDuck (or maybe it was a hammerhead) on our OWC, and it is MUCH more audible. Also, the hand technique doesn't work well with gloves.

    I would think the Duck would be best for class situations, in which you want to have a signal to surface or something (we used it in such a way on our river drift dive).

    According to the instructions that came with my torch, if you don't put the batteries in correctly, it may "explode with a loud noise". Might be difficult to make it go bang at the right moment.

    One of my instructors slaps the face of his watch with the palm of the other hand.

    i heard an instructor complain that he was using his torch as a tank banger. Darn thing flooded after that! *duh*

    So, i wouldn't go round slapping my watch face or dive computer. $200 pieces of equipment are not necessarily indestructible!
