For instance, if you are across a crowded, noisy room from the person you are trying to communicate with, they might not hear your message. For solid communication to happen, your message must travel in a loop that sees it conveyed, received, understood, acknowledged and appropriately responded to. If the message gets hung up along the way, communication breaks down.
This process becomes more complicated when we put a regulator in our mouth and jump into the water. For starters, having the regulator in our mouth makes talking difficult.
Secondly, water makes sound waves go wonky, playing tricks on how we perceive sound underwater. This is why, as part of the Open Water Diver certification course, we all learn a variety of underwater hand signals commonly used in diving.
Good communications starts long before you submerge. Make sure you take the time to discuss with your dive buddy or buddies the various ways in which you all will communicate while diving. This includes going over all the hand signals you will use and what they mean. If you use signals beyond the standard ones taught in your certification course, be sure to demonstrate them to others — including what each signal means. If you are not close enough to reach out and touch your buddy, you can try shouting through the regulator but they might not be able to hear you, especially if facing away from you.
Rather than chasing after them, try getting their attention by making a sound stronger than your voice through the regulator. Try tapping on your tank with a hard object such as a stainless steel clip. Or you can use a nifty accessory aptly named a tank banger, which easily attaches to your scuba tank and produces a loud sound when you bang the device against your scuba tank. It has two operating modes: subsurface and surface. When used at the surface it produces a sound that, according to the manufacturer, has been heard a mile away.
There will certainly be times when you want to share a cool something or other with a buddy and there will be times when you need to gain their attention for safety-related reasons. If you are some distance away, signal by making a circle with both arms, fingertips touching above your head. Any time you are asked if you are okay, answer. Hold your hand out horizontally in front of you, palm facing down and move your hand in a horizontal-to-vertical rocking motion so that your hand goes vertical thumb facing up and then horizontal palm down again.
Do this a few times. For instance, if you are having difficulty equalizing, point to your ear. If you are feeling chilled, cross your arms to simulate shivering. Always monitor your gauges carefully to avoid running low on breathing gas. To signal that you are running low on air, wave a closed fist back and forth at chest level.
Feeling confident that you can communicate clearly will go a long way toward your having a safe and enjoyable dive. Although divers can communicate a lot of different things using simple underwater hand signals, there are some instances where signaling falls short. Ask the staff at your local dive center to show you a few examples. Where in the continental United States can you explore vibrant coral reefs and hundreds of years of historical artifacts while diving in warm, subtropical….Underwater hand signals are the secret language of divers.
Once you get good at them, you can have entire conversations underwater. Some divers even find themselves using scuba diving hand signals on land. Hand signals are also fairly universal. The hand signals for marine life are some of the most fun to learn — and use.
Here are some common underwater hand signals for marine life P for plastic debris. The Plastic Soup Foundation created the new hand signal to help divers raise awareness about the massive problem with plastic.
Sadly, our oceans and waterways are full of plastics. If nothing changes, there will be more plastic than fish in the oceans by Consider sharing some of these striking statistics from National Geographic :. Planet earth needs its human citizens to go on a plastic diet. On average, each person in Europe creates 31 kilos of plastic waste per year. The United States uses around 25 billion styrofoam cups every year and 2. A staggering amount of plastic waste ends up in our oceans. Experts estimate only nine percent of all plastic ever made has likely been recycled.
Underwater, divers have to use our hands to communicate, but topside we can be the voice for the ocean. Read more about the new scuba hand signal at The Plastic Soup Foundation website. Scuba Diving Hand Signals. Megan Denny. Can you translate the following phrases? Look under that rock. Do you want to take a photo of it? See that crab? How much air do you have? Can we end this dive? Follow me to the boat. Share This.Scuba hand signals are essential in your training as a diver because this lets you communicate underwater.
For example, it lets you tell your buddy that you have been diving for long enough and want to warm up after a cold dive. The movements for scuba hand signs are simple and you should be able to perform them at any time, even when wearing dive gloves.
Some might say that they cause stiffer movement for diver hand signals but if you get one of the best selling scuba dive gloves you will not have this problem.
Fortunately, the most used scuba diving hand signs are intuitive so they are easy to remember. Here are some great images from ForDivers. Below are the basic scuba dive hand signals that you should know. Meaning: It is okay. There is no problem. How: Form a circle by touching the tips of your thumb and index finger. The remaining three fingers remain still. These scuba signals are specific to let the boat or your buddy that all is ok at the surface. How: Raise both arms and form a loop above your head by having them meet.
Alternatively, raise one arm up and touch your head. This signal is commonly used to communicate with the dive boat captain. How: Lay your hand out flat with the palm facing down. Once your buddy understood that there is a problem, point to the problem with your index finger.
How: Reach up with one arm and wave above your head. This scuba hand signal is why you should not wave to a dive boat when you do not need any assistance. Meaning: Look at the person signaling or something else in the vicinity. How: First, point at your eyes with your index finger and middle finger.We scuba divers can't talk underwater, yet communication is key for a number of reasons, including safety.
But a good dive buddy also gives his or her fellow divers a heads-up when an interesting ocean creature is nearby. So how do you alert your dive group when a shark is finning by, a crab is hidden under a ledge or a tiny nudibranch is barely visible to the human eye? We've put together 23 scuba diving hand signals for identifying marine life — in the video above, or GIFs below — so that you and your buddies never miss out on spotting some of the ocean's most beloved creatures.
Did you find Nemo? Let your buddy know by making a circular shape with your hand and putting it on your nose — in imitation of a clown's big red nose. Crabs are often found hiding under ledges or in the nooks and crannies of a reef. Pinch the fingers of your hands together like the pincers of a crab for this hand signal. With elongated bodies and sharp teeth, barracuda are easy to spot cruising around the ocean.
Use your fingers to make "stripes" on your arm — to emulate a barracuda's distinctive markings — to point one out. If you spot a dolphin, you better react quickly!
These fascinating marine mammals don't often stick around for long. Use your index finger — or your hand — and undulate it up and down to imitate how a dolphin uses its powerful tail flukes to propel itself through the water. Your buddies will thank you for alerting them to the presence of nearby fire coral, a hydrocoral capable of causing divers great pain when directly contacted. Note the two-part signal: Imitate the "fingers" of coral, followed by pantomining how you'd use your thumb to start the flame on a handheld cigarette lighter.
If your buddy looks like he's asking you for a light underwater, diver beware! It's not hard to spot a group of garden eels — they can be seen on sandy bottoms with their heads popping out of their burrows. Emulate this behavior with your finger to perform this signal. Groupers — especially the Goliath grouper — are known for their big, fat lips and even bigger mouths.
Bend your arms and move them up and down like a large grouper mouth. You can also indicate that there's a large fish nearby by using your hands to gesture something huge.
Take your hand and float it up like a jellyfish — with your fingers trailing like a jelly's tentacles — to let your dive buddy know there's one nearby.Welcome to ScubaBoard, the world's largest scuba diving community.

Scuba Diving Hand Signals Every Diver Should Know
A Free photo gallery to share your dive photos with the world. You can make this box go away Joining is quick and easy. Situation yesterday during a dive pertaining to remaining air signals.
I was with another PADI instructor for a leisure dive yesterday who "misinterpreted" my five fingers up to mean 1, as opposed to because he "thought he saw me flash it twice. He must not have turned around until I was ascending because he didn't realize I was gone. I did the 1 minute under to search for him, then floated at the service for around 5 minutes before kicking back to the boat, then floated near the boat for another 5 minutes.
Scuba Diving Hand Signals
He was no where in sight. He finally emerged after diving to the boat. Needless to say, a lot of recommendations weren't followed, and we should have ensured we had the same hand signals, but fortunately I'm a very comfortable diver albeit new. This was the first time I had seen hand signals in flashes of five, so I didn't understand why he didn't interpret it correctly. Had I been a new OW or uncomfortable diver, this hand signal misinterpretation could have been tragic and turned into panic diver or out-of-air situation quickly.
My question being, what is the PADI and other organizations standards in air signals? If there are several, then why is this not standardized?
ScubaHH6Sep 15, Why not just show your SPG or computer to your buddy? Last edited: Sep 15, AkimboSep 15, Hickdiveundrwaterolyuser and 2 others like this.
In my experience, there is no standard. It MUST be discussed with the dive guide in advance.Vertigo, dizziness and tilting, can happen to any diver which is why it is important to know how to prevent it and what to do when you do experience vertigo. As always, it is important to remain calm and regain control. Disorientation is one of the causes of vertigo which is why knowing how to use a scuba compass is an important skill to help you keep your bearings.
Also, make sure that you are within sight of your dive buddy so they can help you in case of vertigo. This is just one of the many reasons why you should prevent scuba dive buddy separation. Read on for more detailed tips on how to prevent vertigo while underwater. If you are not feeling fit or if you have a medical condition, your chances of experiencing vertigo while diving increases. This is why every dive center always has a health check, whether written or communicated by the dive instructors.
There are several health-related reasons to not go diving. Choosing to dive anyway puts you at greater risk of vertigo and unsafe conditions as a result of it. Something as simple as a cold, flu or indigestion may not seem like a serious condition but they can impact your ability to dive.
It can impact your ability to equalize and your ability to control your buoyancy, both of which are necessary for a safe dive.
Always inform the dive instructors or guides of any medical conditions or medication that you are using because these can also impact your reactivity and control underwater. Certain medical conditions can become exacerbated underwater.
Dive buddies are there for safety reasonsto make sure that you both have a safe dive and to help you in case of emergencies or simply to help you stay calm. This is why it is important to keep communicating with your buddy and check in with each other every few minutes. A bad air fill is very dangerous so do a check before you head out. If you suspect anything wrong with the air fill, directly inform the dive center staff.
During your dive course, you learned the basic hand signals that divers use. Make sure you are both familiar with the same signals and which signals indicate distress or vertigo. Then, once you are underwater, keep communicating. A good dive buddy knows what to do in case of vertigo. The best thing is to help them regain calmness, make sure they keep breathing from the regulator and stop them from rising to the surface too fast.Welcome to ScubaBoard, the world's largest scuba diving community.

If you want to be a good or even the best PADI Diving Instructor or Divemaster then you need to give good and strong hand signals under the water to communicate clearly with your diving students.
What is very important to understand is that there are no standards on how a scuba diving signals has to be given. In other words, it is very important to always go over the hand signals used on that dive before the dive. Especially with new people or diving students. Again you can have slightly different signals, but it has to come close to what it means.
But they do accept different signals for 70 bar as long as they are serious and commonly used. I wish you all the best of success in your Diving Adventures! MaxBottomtimeDec 23, Agree on all points. I review the old chart above now and again though I mostly dive solo. In thinking back, I don't recall any of the dozen or so instructors I assisted going over what their specific signals meant regarding what I was supposed to do next.
Maybe some figured their signals were obvious. Not sure what signals to ask about when your not sure what the instructor may want you to do once under water. I recall when taking AOW my instructor wanted me to do something on the Nav dive something to do with measuring kick cycles.
