    The pitch of the run should be adjusted based on what the material in the box is doing. It will be close but, never really exactly the same. It can be done by eyesight.

    With a sluice on legs the side to side level can be adjusted by eyeballing the water coulumn exiting the box. It will be deeper on the lower side. Pretty easy to see. Also if you run somelights through real quick if they build up on one side ore the other you can tell when your box isn't quite level.

    You could always just mount a bubble permantly to have a visual reference.

    Or just keep a small torpedo level in your pack.

    I had a clinometer app on my phone. But my protective case had a bump on one end that made level not really level.

    When I first started out, I did use a level to setup my sluices and even drew a reference line on one of them until I had gotten enough experience to do it by eyeballing it. Now I know what I'm looking for and it's easier to just eyeball it. I still use my phone app to setup my piglet to a starting point, and then adjust from there depending on what I see.

    Drop it into the water just once, and let's see how level it really is.

    Using a level will place your sluice at the wrong angle 100% of the time.
    You need to adjust the angle according to water velocity and correct performance of the riffles.
