Best bet for BH is a RCBS 505 beam scale. I use it in reloading metallic cartridges. Very accurate. But its not good for arrows. The Cabelas digital is good for archery, but I hate it for powder charges in Reloading. It loses calibration often, and anything can make it lose cal, like a dryer running in the house, or wind, etc.

The RCBS digital is a little better.
