Standard Secchi disk is a white disk, 30 cm in diameter. Small one with black quarters is used in limnology, not in seas and oceans.

thank you very much

[@delarosalouiskentr.2604]

what if the secchi disk that im using does not have a marker or any form of indication....would that mean i have to measure the dept manually??

[@Francois_Dupont]

you can make a knot each meter, put a piece of tape. or just hold the line at that spot and manually measure it on the boat with a tape measure.
