By the way, I've seen Bob L's file in use by his son and it was truly a work of art, plus incredibly useful.

Doug,

Honestly, the MX-3000 is designed for occasional drops on a carpeted surface, but if you want the ultimate in remote reliability use the new MX-900 or the MX-850. Both withstand much higher drops and have smaller LCD areas (any LCD is a target for some two year olds with brand new hammers!). I have an MX-850 that still works after being buried by a dog for several days, dug up again, carried all over the yard and finally retrieved. The dog still eyes it, but the old newspaper roll has discouraged it so far.

Best Regards,

-Eric
