Instructions
Signal sharks with chum. Chum is a mixture of blood, fish guts and assorted parts of fish. Drop chum in the water to attract sharks. Sharks can smell blood in the water up to two miles away. It is best to dive in the protection of a shark cage when signaling sharks with chum. The chum will induce a feeding frenzy and divers do not want to be around hungry sharks.
Signal sharks with audio. Sharks have powerful hearing. They are able to hear splashing birds, seals and fish and zone in on the location simply by hearing it. A shark's attention can be captured by snapping fingers underwater or banging two objects together, like a knife handle on rock. The shark will hear the sound and should take notice.
Signal the shark with movement. Waving the arms or legs in the water will signal the shark. Be careful as some movements may be interpreted as aggressive by the shark.
How to Signal a Shark When You Are Underwater
Diving with sharks can be an exhilarating experience, however, divers must ensure that proper safety precautions have been met. A chain-mail diving suit is always a good idea when shark diving. For divers with no experience with sharks, diving with an expert is highly recommended. Sharks can be signaled a number of ways, due to their wide sensory range. Inexperienced or novice divers may want to consider diving in a shark cage first before free diving with sharks.
