Have you tried talking underwater without using a scuba communicating device? If so, you may have discovered that it didn’t work very well. Our vocal cords are not designed to generate sound underwater though sound travels in water. Now you may be curious how, then, divers use sound to communicate with other divers? Easy peasy. Scuba divers use hand signals to communicate with their buddies. Other than that, they also use writing boards and signal lights, which allow better communication. However, what if the water is murky or the surroundings doesn’t have a good lighting? During these situations, divers use sound to signal their team instead.
- For Effective teamwork
If there is one thing that is essential to working effectively underwater, it’s teamwork. Teamwork requires good communication. Following good protocols is essential for good communications with divers who are working underwater. Communicating properly using either hand signals or signaling devices could save a diver from harm.
- To Avoid miscommunication
Miscommunication may lead not only one diver to danger but may lead the team to harm as well and a diver’s always main priority is safety. For precise communication, most divers use symbols, signals and signaling devices. Signaling devices are very effective communicators. They come in various shapes and sizes. Some are: maracas, torch, marker, sub alert, dive sticks. These are simple but very important in diving.
- To Send an alert
Signaling devices may also used to alert other divers when you are in danger. For this situation, you may use sound signaling devices such as: sub alert which can be heard up to 1.5 miles, an underwater alarm which can be heard 120 meters away or a maraca which can be heard 30 meters away.
