I've been thinking on that, whether an electronic scale would be "best" or use a beam scale or ?
For a mobile kit I'd be a little worried about getting the beam scale damaged; But if you abuse an electronic scale it tends to get pretty sick also! And I might mod the electronic scale if I use one (for example, update it's battery power supply to use 2 AA batteries, which would cheaply last like 5 years, instead of one cheap tiny "coin cell" battery. Should be an improvement. That's what us Embedded folks do to electronics - Mod the heck out of it, if it annoys us. (Friend's shaving razor has a dual external "C" battery pack with two NiMH batteries in there, that thing runs a month between charges or something LOL)
Probably an electronic scale would be smaller and easy enough to pack into a tiny space inside of some protective foam in a "hard case" of some kind; You'd want one that will "Tare" so you can cancel out your powder pan, which could be as simple as a mini muffin liner or the like if you don't want to use a mini measuring cup or partial medicine bottle or the lid of a plastic container (Peanut Butter jar or the like maybe?)
If someone has a better or different idea I'd love to hear it Always things to learn.
(Hoping this is "the" forum for this, as a scale is maybe considered a hand tool? Mods, if I am wrong, feel free to move this, just don't string me up please LOL)
