What is the diameter of the disk?

The diameter is about 7 1/2 inches.

can i use this for multiple testing?

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.

Is the line calibrated?

There is a black mark on the yellow line every 12 inches.

Does it sink quickly?

Yes, it sinks fairly quickly as the weight underneath is significantly heavier than the disk.
