Lost buddy procedure
Becoming separated from your buddy is a stressful situation that requires a calm, disciplined response. Your training defines the standard procedure; do not improvise.
Stop, think, act
The lost buddy procedure is a fundamental skill that must be practiced to be effective. Follow the standard one-minute search protocol taught by your agency.
The initial reaction
Upon realizing your buddy is not visible, stop. Do not bolt for the surface, but check the immediate area, including looking up and turning 360 degrees.
If they remain missing, recall the last time you saw them. Assess the environment, including visibility and current, then prepare for a search.
Conducting the search
Search for no more than one minute, as taught by your training organization. Look for bubbles, lights, or equipment silhouettes against the light.
If the search is unsuccessful, begin a controlled, safe ascent. Signal your location if possible, but keep your safety as the priority.
The surface meeting
Once at the surface, establish buoyancy and look for your buddy. If you do not see them, signal for assistance or head to the exit point as planned.
Review the separation afterward. Understanding why the separation occurred is key to preventing it from happening again.
