This tool allows you to get an estimate of all of your sight marks from just two known sight marks.
Please enter two known sight marks below. The further apart the sight marks are the more accurate the estimates are likely to be. You may enter either yard or meter sight marks but ensure the “Units” are set correctly. It is not necessary to use the same units for each of the sight marks.
