Secchi Disk and Decals

The plastic Secchi disk is a standard for measuring the relative visibility of water. Lower it into the water and when it disappears, record its depth. SEC is a LaMotte® silk-screened plastic disk with stainless steel eye bolt and lead weight. 21 oz, 8" (20 cm) diameter, lowering line not included.

SE1 is a black and white vinyl decal for freshening up any 8" Secchi disk or for making your own.
