That is simply not true, and I doubt Bird would claim that either.

Whether there is a more accurate "field" type instrument  I do not know, 
but there are more accurate lab instruments around, but these are not 
convenient to use for the sort of thing a Bird gets used for.

I have nothing against the Birds. They do a good job, but they are not 
as accurate as what Bird claim.
