Silt cloud left us blind, so we 'talked' with our gloves

I was on a harbor inspection dive (the kind that gets muddy fast) when a silt cloud rolled in and killed our view. We had drilled touch signals before, but using them for real was a different story. I found that a simple tap code on my buddy's arm kept us on track and safe. Has anyone else had to switch to full touch communication down there? I'd love to hear how other teams set up for these zero-vis moments.
