New tag revolutionizes whale research. Each click contains a series of smaller clicks interlaced within, and a series of even smaller clicks within those, and so on. The energy from the smallest clicks is so strong that you can really feel it tingling through your body. You should not have to do this in order to swim up to the surface if you are correctly weighted to be neutrally buoyant, but you might need to do it once you are there.
