Scuba diving hand signals
Isyarat di bawah ini benar-benar digunakan oleh penyelam. Ini adalah referensi, bukan standar: pelatihan lembaga Anda dan pengarahan sebelum menyelam menentukan apa yang Anda gunakan di air. Sepakati isyarat tersebut dengan rekan selam Anda sebelum setiap penyelaman — termasuk yang menurut Anda sudah jelas.
Halaman ini melengkapi, dan tidak pernah menggantikan, standar keselamatan dan pelatihan SSI, PADI, CMAS, RAID dan lembaga lainnya. Isyarat disepakati saat pengarahan. Jangan pernah menggunakan praktik kesadaran penuh selama fase yang memerlukan pelaksanaan tugas kritis, dan jangan pernah menahan napas saat menyelam dengan scuba.
The essential five
Agreed before every dive, by every diver, in every language.
OK
Caranya
Thumb and index finger joined in a circle, the other three fingers extended. With gloves or at distance, arm over the head in a circle.Sarana
Both a question and an answer. Asked, it must be answered — silence is not an OK.Not OK / problem
Caranya
Flat hand, palm down, rocked side to side, then point at what is wrong.Sarana
Something is off. Say it early, at amber, not late at red.Up / end the dive
Caranya
Closed fist, thumb up.Sarana
An instruction, not an opinion. Any diver may end any dive, at any time, without giving a reason.Down / descend
Caranya
Closed fist, thumb down.Sarana
Begin or continue the descent, at the agreed rate.Stop / hold
Caranya
Flat open palm facing the buddy.Sarana
Stop adding tasks and stabilise here. The most under-used signal in diving.
Gas and pressure
Numbers vary by agency and by region. Agree yours on the surface.
How much gas?
Caranya
Flat hand tapped twice against the open palm of the other hand, or two fingers to the palm.Sarana
Answer with numbers, honestly and immediately.Half / turn pressure
Caranya
Flat hand held horizontally at chest height, or the agreed number shown on fingers.Sarana
The turn point of the dive plan has arrived.Low on gas
Caranya
Closed fist to the centre of the chest.Sarana
Reserve reached. Begin the ascent plan now, together.Out of gas
Caranya
Flat hand drawn across the throat.Sarana
An emergency. Follow the out-of-gas procedure you trained with your agency and rehearsed with this buddy.Share gas
Caranya
Fingers of a flat hand brought to the mouth, then reaching toward the buddy's alternate.Sarana
Give me your alternate air source. Practised on land, then in shallow water, before it is needed.
Direction, depth and pace
Most task-loading happens here. Keep signals slow and single.
Look / watch me
Caranya
Two fingers pointed toward your own eyes, then toward the object.Sarana
Direct your attention here.Go that way
Caranya
Flat hand held vertically, fingers pointing in the direction of travel.Sarana
The agreed heading.Slow down
Caranya
Flat hand, palm down, pressed gently downward.Sarana
Reduce pace and workload. Almost always the right answer.Level off / stay at this depth
Caranya
Flat hand, palm down, held steady and horizontal.Sarana
Hold this depth.Safety stop
Caranya
Three fingers raised over a flat horizontal hand: three minutes, five metres.Sarana
Hold the stop as planned. A good moment for slow, continuous breathing — nothing else.Stay together
Caranya
Two index fingers held side by side.Sarana
Close the distance and dive as a pair.
Problems and the body
Naming a small problem early is the whole skill.
Ear problem
Caranya
Point to the ear.Sarana
Equalisation is not working. Stop the descent, ascend slightly, try again gently. Never force.Cold
Caranya
Arms crossed over the chest, hands rubbing the upper arms.Sarana
Thermal reserve is going. Cold is a common quiet cause of anxiety and short dives.Cramp
Caranya
Two fists brought together and pulled apart.Sarana
Stop, stretch, let the buddy help.Slow your breathing
Caranya
Flat hand moved slowly up and down in front of the chest.Sarana
Return to slow, continuous breathing. Never breath-holding, skip-breathing or hypoventilation.Dizzy / disoriented
Caranya
Index finger circled beside the head.Sarana
Hold on to something stable, hold depth, signal the buddy and end the dive if it persists.
Galeri Air
Tiga tambahan yang kita sepakati di permukaan
Rangkaian isyarat standar sangat baik untuk keadaan darurat, tetapi hampir tidak menyampaikan kondisi sesaat sebelum keadaan darurat terjadi. Ketiga isyarat ini disepakati dalam Kesepakatan Rekan Selam sebelum masuk ke air, sebagai tambahan — bukan pengganti — isyarat lembaga sertifikasi Anda.
Amber
Flat hand tilted side to side, then the OK question. Agreed in the Buddy Agreement before entry.
I am not in trouble, and I am not fine. Slow down, stay close, check me again in a minute.
Settle
Open palm lowered slowly, held still for one full breath cycle.
Nothing is wrong. Take one breath here before the next task. The in-water form of STILL.
Notice this
Two fingers to the eyes, then held open toward the water rather than at an object.
Not a fish or a hazard — the whole scene. An invitation to look wide for a moment.
Kartu Belajar
Satu isyarat setiap kali. Baca namanya, bayangkan posisi tangan, lalu balik kartu untuk memeriksa bentuk dan maknanya.
Pemeriksaan singkat
Delapan isyarat, masing-masing dengan satu bentuk. Setiap jawaban disertai alasan — makna lebih penting daripada skor.

Common questions
Are scuba hand signals the same in every agency and country?
The essential signals — OK, up, down, stop, out of gas — are effectively universal across SSI, PADI, CMAS, RAID and others. Beyond those, details differ by agency, region and dive site. That is why the briefing, not the internet, is the final authority: agree your signals with your buddy and guide before every dive.
What is the most important hand signal in diving?
The thumb up. It ends the dive, it is an instruction rather than a request, and any diver may give it at any time without providing a reason. A close second is the flat open palm — stop — because most incidents grow out of tasks added on top of a situation that was already full.
Why is thumb up 'ascend' rather than OK?
Because on land the thumb up means approval, and underwater it means end the dive. Confusing the two costs dives and occasionally more. Underwater, OK is always the finger-and-thumb circle, never the thumb alone.
How do I signal that I am anxious but not in danger?
Most standard signal sets have no word for this, which is why divers stay silent until the situation is red. Mindful Diving™ adds an agreed amber signal — not in trouble, not fine — so the pair can slow down and stay close early. It is agreed on the surface in the Buddy Agreement and never replaces an agency signal.
Can I practise hand signals before diving?
Yes, and it is the cheapest safety practice there is. Run through the whole set on land with your buddy, then again with masks on in shallow water. Signals you have rehearsed together arrive faster than signals you have only read.
