Ive heard a lot of bad things about the really exspensive digital powder scales and have something that might make the people that have paid a lot for there digital scales a bit on the angerd side. I smoke a hooka every now and than and when i was at the local head shop found that they sold some cheap digital scales that mesured points. on a whim i looked at them wondering if maby they would do grains and sure enough i found one that is a silver modle that is bout the same size as a persons palm giver or take. Took it home for i think $20 bucks and sat down with my normal beam scales and my powder throw and started messing around with it. Come to find out that the same scales that pot heads use for the good stuff has a mesurmant for grains. Tested it and checked it with my zeroed lee scales and it hit the mark acuratly every time. Of corse i double check it every 10 rounds or so just to make sure but I have never had an issue with it being off. Hope that helps some people save some cash its modle number usn-500 500gx0.1g Just couldnt see spending $80+ on powder scales.
