The OMS Fluorescent Dye marker leaves a substantial discoloration of a huge amount of water in your immediate area which greatly increases your visibility for both the dive boat as well as air support. It significantly increases your chance of being spotted in am emergency situation.

As an added benefit it also reflects and is highlighted by sunlight increasing your visibility even in daylight.
