Good communication between dive buddies is essential to a safe and enjoyable dive. Signaling can help you to communicate intentions, give direction, ask your dive buddy if they’re okay, how much air they have, or inform them about a problem. The most common method of underwater communication is through hand signals. However, such factors as darkness, silt, or plankton can affect the visibility underwater in a negative way and hamper your ability to communicate effectively. So what do you do, if there is a risk you may not be able to use hand signals? Let’s look at a few alternative methods of communication that you can use depending on dive conditions.
Night diving is one of those things that are fascinating and frightening at the same time. Many divers, afraid of what might be lurking beyond the beam of their dive light, are hesitant to go down into dark waters. However, just a bit of mental adjustment, training, and proper dive equipment can make night driving an incredibly rewarding activity. In fact, some divers enjoy the tranquility of diving in darkness and the slower pace of a night dive so much that it becomes their favorite type of diving.
