What the Course Entails and Exam Details

This comprehensive specialty program delves into the specific knowledge and techniques required for night and limited visibility diving. Students learn about specialized equipment such as primary and backup dive lights, light systems, and navigation aids. The course covers planning night dives, entries and exits, descent and ascent techniques without visual references, and maintaining buddy contact. Specialized light communication signals and hand signals are a crucial focus. Divers also learn standard operating procedures for managing situations like light failure or becoming separated from their buddy in poor conditions. The practical component involves applying these skills during at least two open water dives.

What to Expect in the Final Exam

The SSI SC-LV knowledge assessment typically consists of a multiple-choice written exam, often administered through the online MySSI portal or a hard copy. Students are tested on their understanding of planning, equipment, navigation, communication, and managing limited visibility hazards. The passing score is generally 80% or higher. There is usually no fixed time limit, allowing for careful completion, but it typically takes 60-90 minutes. Reviewing digital learning materials and discussing concepts with an instructor is essential. Practical skills are evaluated separately during the required dives.

How to Study and Exam Centers

Preparation is key. Thoroughly review the SSI Night Diving & Limited Visibility digital manual or textbook. Focus on key definitions, equipment functions, signaling procedures, and emergency actions. Use knowledge reviews within the materials as a self-check, and utilize online resources and practice questions where available. Group study or discussing tricky scenarios with other divers can be very effective. Practice light signaling and navigation techniques before getting in the water. The actual final exam is completed online through your MySSI account after purchasing the materials, or can be taken at any authorized SSI Training Center (Dive Shop or Resort) worldwide where you are completing your practical training.
