Loving the transformers tats , they are so cool , the original prime and megatron wow . Got the magnet implant done by a guy in worksop his shops called body alter , think he's got a Facebook page , got my other stuff done by him but can't mention them for family reasons ( sorry about that ) . It does have its uses like pickin up sewing needles and other sharp stuff and like you said it picks body clips and screws up really easy so if its in long grass and you got a rough idea where it is your sorted . You can also feel the magnetic field given of by a microwave or an electric motor on a fan and other stuff
