<P> A different voice - over track is recorded for US audiences by Brooks Moore ( seasons 1 -- 8 , 2001 -- 2007 , 2008 -- present ) and Zac Fine ( 2007 -- 2008 ) . The scripts are almost identical but the main difference in the US versions are that the units of measurement are given in United States customary units instead of metric units . At one point in the US run , a subtitled conversion was shown on - screen over the original narration . </P>
