I'm looking for resources for building secchi disks. I found this one online, but I haven't had the chance to test it out yet. Has anyone built one before? How did it go?
Very cool! i haven't but seems pretty straightforward just like the technique itself. If you have other uses for black and white rust resistant paint, or are building them in bulk buying the spray paint makes sense, but if only making one set buying secchi decals might be cheaper and have less waste ($7) https://pentairaes.com/secchi-disk-and-decals.html?gclid=CjwKCAjw4sLVBRAlEiwASblR--wjmo4Ho96FnH-z1trGBpQa-cN4gzCKNzD9RJ-e4Uxu1QZAcOtocBoCQmgQAvD_BwE

Oh that decal is nice! I also found a couple really inexpensive secchi disks $18-$25 verses the Lamotte ones which are around $42-70.
Oh those are great finds! I would think for $18 that is probably just as (if not more) affordable as making it one's self (including labor time). I'm not sure if there is an epistemological gain from making this device one's self (no hidden process or mystifying technologies inside). But making it can still be fun :) I wish all enviro monitoring tools could be as beautifully simple as secchi disks.
