From their website:
"Using an ultra-sensitive mechanical balance beam system comprised of primarily non-ferrous metals, the Prometheus Gen II is extremely resilient against the presence of lighting ballasts, cell phones, and other sources of electromagnetic interference. Electronic scales can hide behind a digital display and only show you what they want to.
With the Prometheus Gen II you can see the needle move yourself. If something is affecting your charge weight, it won't be shrouded in electronic programming and hidden from view, you'll see every moment of the weighing process clearly."
I rest my case, pardon the pun.
Overkill for shotshell reloading, of course.
