Not me my partner used to always carry her jar in her shirt top pocket, button undone.
She usually drags a chain when looking and hoping for a patch. Well the long and short of it, she got a signal' dug a nugget, but jar was gone. (Those pointy bits women have must have dislodged the jar)
We back tracked (tears streaming down her face, there was about 10g of nugs in the jar along with her test piece, (first nug she ever found.) along her drag mark and there in amongst the rubble was her jar, easily visible due to the fluorescent green paint I had covered the jar with.
**After getting home, out came the sewing machine and a zippered pouch was added to her detector cover.**
