Saw a couple of folks asking so I made a little video with the machine and various rings. This is an air test showing you the VDI numbers and tones of the following rings. Silver, Titanium, Gold and Platinum. To my surprise all the rings with the exception of the Silver ring Id'ed in the mid 40's on my machine. Video quality isn't the greatest, but HD video takes to long to upload to youtube on my computer. Dinosaur! Anyway hope this helps someone out there find some rings on land or at the beach. Good Luck.
