If you have the choice between analog scales and digital scales, you should always choose the digital scales. Because on one hand digital scales have a higher accuracy in weighing, on the other hand the possibility of making mistakes when reading the values is much lower. Also you are able to weigh much smaller amounts. Today the energy use of digital scales is not high, thus their duration is greater. There are digital scales in different sizes, so that a pocket scale or special accuracy weighing machine will always fit your pocket en route.
