Low vis is extremely easy to figure out... Jump in the water and look down. If you're six feet tall and have on fins (about 18 inches) and can barely see the fin tips, the vis is about 7-8 feet... can only see half your body... vis is 3-4 feet.
Use this same concept to establish vis of greater distance. Determine your distance with body length and fin kicks. Its not an exact science, but you can definately estimate within 10 feet what the vis is. Use your body and or your buddy for measuring distance. Once you master it, you can safely tell someone vis was 30-40 feet 70-80 feet etc...
