What should you and your buddy do if separated during a dive?

If you get separated from your dive buddy during a dive, stop and do a slow visual 360-degree spin. In doing so always remember to look up and down too. Look for telltale signs like your buddy’s bubbles or any disturbance of silt or sand on the bottom. If you have an audio buddy signaling device like a tank banger or a similar, and if you can’t spot your buddy, use it to see if your buddy can locate you from the sound.
