Underwater alarm?

Does anyone have suggestions for an underwater device to signal swimmers? We'd be using it from a kayak, so something along the lines of a "clicker" might work the best. Any ideas? Thanks. JB

JB I'm not sure what you're trying to accomplish with this, but my most un-ignorable method at the pool involves banging on the pool ladders with a wrench. Much more effective than yelling or whistling. So try a short length of pipe and something to bang with, should be able to handle that in a kayak. Make sure the pipe is in the water when you bang it!

    Are you referring to getting the attention of swimmers in the open water? Standard whistles are effectively used at professional marathon swims, solo swims (including those done by blind swimmers) and at international FINA competitions to catch the attention of swimmers from nearby escort boats or referee's boats. In addition to the audio warning, visual warnings are also given through hand signals or yellow/red/neon-colored flags or boards. In the open water, sticking a pipe in the water and striking it with a hammer or wrench would also catch my attention, depending on how far away I was from the kayaker.
  • We do an 30 mile open water relay swim that circumnavigates a local island. Some of the kayak support guys were having a hard time getting the attention of their more "focused" swimmers. I'm trying to find something to help that situation.

    It's alright cos you hear really loud music when the shark is getting near, so you know to get out of the water.
