Is the magnet in this strong enough to damage dive computers, cameras or other electronics? Thank you, Ashley

Hi Ashley,Thanks for your question. No, the magnet is strong enough to damage electronics. If you have any other questions, please let us know.ThanksDivemaster Chris866-728-2293

It is 6 1/4" long. The string is not as long as in the picture, you cannot loop it through, but it can be replaced.

What material is the cylinder made of? Could it also be used to "bang a tank" if the rattle function fails?

This shaker is made from anodized aluminum. It can be used to bang your tank in an emergency but you might scratch or dent your rattler.
