But if I were a proper American, I should've thrown it in the trash 15-17 years ago and purchased a new one, for no valid reason. I've had a Taylor digital thermometer on my pool for over a decade. It's been exposed to the elements of winter, spring, summer and fall for that time. I recently purchased a new digital thermometer with a longer probe lead because I wanted to move the location of this thermometer. I tested both in some tap water and both are within .1 degF! So old, just as you have stated, doesn't mean that it's de facto obsolete. If it ain't broke, don't fix it. If it ain't broke, don't replace it. This crap just makes me sick. Me too. -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG Well I speak to machines with the voice of humanity.
