Tumblers I use all the time, not sure if I would need an ultrasonic. They both serve two different cleaning purposes....although the tumbler can be really noisy. I only use the tumbler for crude relics, clad, and crusty wheat cents.metal mania said:ultra sound vs rock tumbler which wins in terms results and or noise levels

I have used both.
For cleaning old coins (Not rare ones) = Tumbler
For cleaning Jewellery with precious/semi precious stones = Ultrasonic cleaner
Rings etc without stones, I use Silvo / Brasso or similar then buff them up.
