## Description

The Secchi disk has been a valuable tool since it was first created by Angelo Secchi back in 1865. Our Test Assured Secchi disk includes everything you need to get started and is one of the most high-quality discs on the market.SIMPLE & EFFECTIVE TOOL:Secchi disk is a simple and effective tool that allows you to determine the productivity of freshwater lakes. Constructed of sturdy white plastic, the disk alternates between white and black printed quadrants. Fused to the bottom of the disk is a weight to help it sink. Attached at the center of the top side is the 100-foot cord which includes a polymer foam bobbin for visibility.FEATURES:● Weighted, black and white solid plastic Secchi disc● 72’ rot-proof polymer cord● Spool to wind excess cord● Detailed instruction manualINDICATION OF TURBID WATER:Measurements are taken by lowering the Secchi disk until it can no longer be seen. This point is known as the Secchi depth. Because light can penetrate deeper in clear water, the further the disk sinks, the higher the Secchi depth, which indicates clearer waters. The presence of high concentrations of algae and particulate in the water decrease visibility, in turn, decreasing the Secchi depth measurement, indicating turbid water. BENEFITS:● Indicate Clearer Water● Test Various Kinds of Water● Check the turbidity of water● Designed for use in Shallow Water● Perfect for Various DepthNUMEROUS READINGS FOR WATER:Lake transparency can change with the seasons due to temperature and the amount of exposure to sunlight. It is important to take numerous Secchi disk readings throughout the year. An increase in Secchi depth shows improvement in water quality, while a decrease shows that water quality is declining.

## Features

- EASY TO USE: Secchi Disk with Lanyard Includes everything you need to get started. It includes disk, cord, cord holder & instructions. The Secchi Disk is used to measure how deep a person can see into the water. This is a measurement of water clarity.
- WATER TRANSPARENCY MEASUREMENTS: Test Assured Secchi Disc is a timeless tool for checking water transparency in any body of water. This clarity measurement is required by a majority of the states’ health boards. Close to 100ft of cord is included to ensure you have enough for any water testing situation.
- Multipurpose Disk: Secchi Disk is used to determine the transparency of water in lakes, streams, oceans, and other bodies of water. It is an eight-inch diameter disk with alternate black and white quadrants. By placing the disk in water and holding onto the string a user can measure the clarity of water.
- DETERMINE TURBIDITY OF WATER: This black and white disk is used to determine the turbidity of natural water. The disk is raised or lowered several times to determine the average depth at which it disappears from sight. It includes a sounding lead and line.
- SUITABLE FOR VARIOUS DEPTH: The Secchi disk is designed for use in shallow water and works best in shaded areas to eliminate glare from the sun. A best practice is to use the average of two depth measurements. With 72 feet of cord, it is suitable for a variety of depths.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good disk, but rope needs attention
*by C***. on September 19, 2021*

This is a nice disk, well weighted and seems sturdy. After reading other reviews, I made sure to check the "rope," which is not as sturdy. It was very loosely tied on. I ended up reattaching the rope using a clip-on hook, with good knots and tape. I also added my own measurements with a sharpie pen. I'm glad I checked, otherwise I fear my disk would have ended up at the bottom of the lake. But the quality of the disk itself is good, and the price was very reasonable, so I'm giving it 5 stars anyway.

### ⭐⭐⭐⭐ Great alternative to the Batarang!
*by K***A on July 28, 2019*

So far, I've not caught any decent sized fish with this. Though I imagine it might give a crab a good headache. ;-D. jk - it's a Secchi disk. It measures turbidity in the water. It does a good job though it is just a bit smaller in diameter than most Secchi disks I've used, so not exactly certain how comparable its results are with a larger one (that you may be able to see a little further down). Also, would have been great if it came with a marked rope. As it is, I just knotted the rope every half meter and it works just fine.

### ⭐⭐⭐⭐⭐ Great secchi disk. Would buy again!
*by K***R on September 13, 2017*

This is a great product for the price. There's a lot of expensive ones out there but this one works just as great! Sturdy plastic disk & nice weight at the end.
