Tester la profondeur de l’eau d’un lac

I needed this disc for work (wetland work on Lake Ontario), as we do water quality monitoring quite frequently and had recently lost our metal, heavier duty Secchi disk. The disc itself works as it should, though it is made of thin plastic and probably would not withstand too much hard use and would likely break if dropped on any hard surface or hitting obstructions (i.e. rocks) when lowering in the water. The weight attached to the disk is heavy enough to prevent too much drift in slow-moderate current, making it easier to record measurements in flowing water. The line that came attached to the disk is not the strongest, and the measurement markings made on the ""calibrated" line were incorrect or followed no consistent pattern, so I had to add my own. Otherwise, the disk worked in a pinch and will suffice as advertised.

We use it for water clarity level

Secchi disk is solid, tho the string is a bit flimsey
