You can add my name to the list of those who would like a solution to this problem. Typical probe life is 10-12 weeks for an experienced operator. If the tip does not break, it wears down to a nub. If you train a new operator, buy a new proble before the training begins - you'll need it by the end of the first week! We don't need no "stinkin" probe.
