## Description

7.87 Inch Plastic Secchi Disk Set Secchi Disc with Black and White Quadrants, Steel Cone, Holding Line and 100 ft Tape Measure for Clarity Measurements

## Features

- Comprehensive Package: every purchase of the set includes the items you need for water clarity measurements; The package contains 1 piece of Secchi disk, 1 roll of holding string, 1 piece of cone weight, and 1 piece of tape measure; This ensures that you have tools to accurately measure both fresh and seawater transparency
- Ideal Size: bearing a diameter of around 7.87 inches/20 cm, the Secchi disc is suitably sized for efficient visibility under water; Meanwhile, the tape measure features a measurement of about 100 ft/ 30 meters, and the rope is about 16.4 ft/ 5 meter long, measurements that allow ample depth tolerance for deep water clarity measurement without hindrance
- Quality Materials: the acrylic Secchi disc, the pivotal piece, is made from acrylic which ensures its resilience, lightweight and portable; The cone, designed to weigh down the disk, is crafted from stainless steel ensuring its longevity, hard to rust; The holding string is made from robust polymer to handle the disk and cone weight without elasticity, hard to tear and sturdy for long time use
- Freshwater Measuring: use the black and white side, and when the water surface is stable on an unclouded day, lower the acrylic Secchi disk into the water with a holding rope until the disc can hardly be seen from above; Measure the length of the rope immersed in water, repeat it several times, and get the average to get freshwater clarity
- Saltwater Measuring: use the pure white side, at the backlight of the main deck, put plastic Secchi disc into the water, and sink to a depth just out of sight; Then slowly lift the rope until the dish is faintly visible, read the mark of the rope on the water surface, repeat for 2 or 3 times and take the average to get observed clarity; Read the mark of the rope at the crest and trough respectively when wavy, if the inclination angle exceeds 15, the depth should be corrected

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to see easy to read
*by D***Y on September 12, 2024*

Bright color and balancing weight makes this easy to use

### ⭐ Plastic is thin and breaks easily
*by J***E on December 27, 2024*

I was setting this up to use for the first time and the thin plastic disc broke when being dropped from 2 feet. We never even had a chance to get it into the water! Total garbage.

### ⭐⭐ Poor construction
*by J***C on August 15, 2024*

This worked well in lake water for about 10 uses, but now the tape rubs against the plastic holder and will not rewind smoothly.
