Which buddy system technique is recommended when diving in limited visibility?

Using a buddy line or holding hands is recommended when diving in limited visibility because it enhances safety and communication between dive partners. In situations where visibility is poor, divers may have difficulty spotting each other or maintaining a sense of direction. By physically connecting, such as through a buddy line or holding hands, divers can keep track of each other’s locations and ensure that they are both safe and oriented as they navigate the underwater environment.

This method allows for immediate physical contact and provides reassurance, promoting a sense of teamwork. Additionally, in the event of an emergency or if one diver needs assistance, being connected can facilitate quicker responses and help avoid separation, which can be critical in limited visibility scenarios.

While other techniques, such as diving in a staggered formation or staying within visual range, have their own advantages, they may not be as effective when visibility is compromised. Using whistles can also aid communication but may not be reliable as a primary communication method under water, especially if sound is dampened or if divers are far apart. Therefore, maintaining a physical connection is the safest and most effective technique in low visibility conditions.
