What is required for all MK 25 dives?

• A. Buddy line
• B. Buddy system
• C. Safety tether
• D. Pre-dive checklist

Answer: (A)

In MK 25 dives the emphasis is on keeping constant, tangible contact with your buddy through a dedicated tether. The buddy line provides a direct physical connection that helps you stay together in confined or low-visibility environments where verbal cues or hand signals can fail. It acts as a safety tether you can feel and follow, making it easier to locate a partner quickly, control movement as a pair, and retrieve gear or assist each other if something snags or a problem arises. While practicing with a buddy system and running pre-dive checks are important general safety habits, the specific requirement for these dives is the buddy line, because it gives an immediate, reliable means to maintain contact and coordinated action in challenging conditions.
