I was pretty impressed with the production quality of the video—titling, captioning and lighting. Rather than a desktop demonstration unit made from dimensional lumber, it could have hollow plastic tubing for arms with the cable run inside and be hung from a engine hoist for maneuverability.
The 'Unispotter' is one-sided, with the arc between a ring and post, but that should work on sheet metal. I'll probably retrieve it tomorrow unless it's already here and I just can't find it. That happens a lot.
