I know there have been many posts but I'd like to share what I use.
Loupe: B&L 5X
B&L 10X Coddington
Scale: Acculab Model 333 Electronic Digital
capacity-300g
graduation-0.1g
accuracy- +-0.1g
weighing mode- g., oz., ozt., dwt.
AC or 9volt w/adaptor
Mem., Tare function
Calbration weight
The loupes serve 99% of my needs. The scale is a pleasure to use. I've had it for approx. 10 years and it's still like new.
Hope this may aide you. Mike
