The tape measure has been a constant companion of the working man for years. 
Just when you think everything that could go digital has already done
so, we see this bastion of tradition now in digital form. (w/pic)

It looks
like a standard retractable tape measure, but it includes an LCD
display on the top that can display and store measurements down to 1/16
of an inch. It includes several different units for measurement and can
take into account the length of the casing, when you are measuring in
tight places.

When you pull the tape out it will automatically turn on and
retracting it will turn it off. That way you don’t forget about it and
find the device drained when you really need it. It’s only $25.
