The Smart Weigh scales are very popular because they are accurate but not too pricey. This one, the SWS600 Elite, measures minuscule amounts down to a tenth of a gram. Just as critical, it has a tare function. That means you can place a rolling paper on the scale, hit the tare function button, and the scale will go back to zero. Then pile on your leaves, and the scale will show you the weight of the weed without the paper.
Also important is the fact that the SWS600 is small and portable. It runs on AAA batteries that won’t need replacing for a long time even if you use it every day. And if you want to weigh something bigger, its scale cover converts into a weighing tray for up to 600 grams, or 1.32 pounds.
