A trick for clearing silt in a zero-vis harbor job in Seattle
We had to inspect a piling in Elliott Bay with zero visibility from stirred up mud. Instead of the usual fanning, I tried a small bilge pump on a low setting to push water down and create a clean column. It worked for about 15 minutes before the current messed it up, but it was enough to get the shot. Has anyone else tried something like this, or is it just asking for trouble with more silt?

Hey @shane_ross, a sleeve might actually trap more silt if it hits the bottom.

Smart move using the bilge pump. You could try a weighted sleeve around the hose to keep the current from pushing it around so much. Maybe even a small cone to direct the flow better and make that clear column last longer.
