First of all, the top loading balances are less precise by a factor of 10 and secondly, air currents around the pan can reduce that precision by as much as another factor of 3 or 4. But the top loading balance is the instrument of choice where precision is not of great importance. Here is one our top loading balances.
1 What you do now is put one rock from this pile on each side of the scale. 2  Like before, if the scale tips to one side, the lighter pebble is on the scale. 3  If the scale is balanced, then the remaining pebble is the lighter one. 4  And that was the last turn on the scale.
