Need to measure really big powder charges? The Accu- Touch 2000 gives you +/- .10 grain accuracy on charges up to 2,000 grains, and you can set it to read out in grains or grams. With easy-to-use touch screen controls and a removable powder trickler that can be mounted on either side to accommodate both left and right hand users, the Accu-Touch 2000 really streamlines the task of measuring out precise, consistent powder charges. Runs on a 9 volt battery (not included) or the included universal AC adapter. Comes with a calibration weight and a fold-back dust cover.
