## Questions & Answers

**Q: What is the diameter of the disk?**
A: The diameter is about 7 1/2 inches.

**Q: can i use this for multiple testing?**
A: Yes, you can use it for multiple testings, although I found that in an area with a current the disc will break after about 10 to 15 testing runs.

**Q: Is the line calibrated?**
A: There is a black mark on the yellow line every 12 inches.

**Q: Does it sink quickly?**
A: Yes, it sinks fairly quickly as the weight underneath is significantly heavier than the disk.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Secchi
*by K***N on June 27, 2021*

Very high quality product. One of the better secchi disks I have. No fading, centers very well.

### ⭐⭐⭐ It works
*by K***Y on November 20, 2024*

Works but not a professional quality. The string is just a string and the plate is pretty thin. It does not like a current or moving waterways. Would suggest upgrading to a marked small rope because the string is gonna become a tangled mess someday.

### ⭐⭐⭐⭐⭐ Works great fir iur association's private lake
