Accurate to .1 grains. Measures grams, grains, ounces, carats, etc etc, all the typical weights for a digital scale of this type, up to 100grams total. Bought from Brian Enos website. Consistent, accurate, and you can trickle with it. Cheaper ones lag too much when trickling. Uses AA batteries. Includes calibration weight. Only selling because I got an AC powered setup. Paid $70 for it. Asking $40 shipped. Less than a year old.
