    How Antimagnetic is a MT-G?

    Hi, I'm a long time lurker and a first time writer. I just got a MTG-520 today at a thrift store and was wondering just how antimagnetic it really is.

    Can I wear it in an MRI for instance or near a thumpin' bass speaker?

    Thanks for the information.

    Chad

    Hi Chad, the antimagnetic properties of the watch are finite for sure, were you to take the caseback off and lift the rubber shroud you would see the layer of metal shielding providing the magnetic resistance is quite thin, however this is enough to protect the tiny stepping motor that moves the hands from quite strong fields. I would say it should be fine near your speakers.

    An MRI scanner is a different animal however. I think I'm right in saying we've had reports of strange things happening to Gs near MRI machines? So maybe it's best to give that one a wide berth, unless you want to do a test of course :)

    I don't have ready access to a MRI, but my wife is a nurse so maybe...

    I was just curious since the Casio webpage says "
    Though this watch is designed to withstand exposure to magnetic force, you should still keep it away from machinery and appliances that generate a strong magnetic field."

    It isn't as bad as saying its antimagnetic if you never get it near a magnetic field but I was wondering how strong strong is?

    Hi Chad,

    I wouldn't wear it near an MRI machine. One of the members here, Mike Hogan, works in the medical field and he happened to be wearing one of his G's while working by a MRI machine and it died on him. I think he replaced the solar cells and it was fine after that. I'd maybe search for that thread before just to check and see just what happened. Better safe than sorry.

    Hi again Chad,

    Here is one of the threads about an MRI machine.
