## 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.
