Night Limited Visibility Diver (SDI)

If you want to dive comfortably when the sun goes down—or when visibility is reduced—this course gives you a clear, repeatable system for staying oriented, communicating effectively, and managing risk in low light. You’ll learn how to plan the dive, choose and use the right lighting, maintain buddy contact, and respond calmly to common issues like disorientation or a light failure.

Training is private or semi-private (1–2 students), so you move at a steady pace with coaching that matches your comfort level. Successful completion earns a specialty certification focused on night and limited-visibility diving skills.

• How to plan a night/limited-visibility dive with conservative limits and clear contingencies
• Primary and backup light selection, setup, and in-water handling
• Effective buddy contact methods for low visibility (including buddy-line concepts when appropriate)
• Light-based communication and practical teamwork at distance
• Navigation strategies using compass, bottom contour, and natural references when cues are limited
• Entry/exit procedures and surface signaling considerations in low light
• How to prevent and manage disorientation, lost-buddy situations, and light failures
• Task loading management: buoyancy, trim, breathing, and awareness while operating lights and navigation tools
• How to brief, debrief, and log dives with meaningful notes that improve future dives

• Improves situational awareness when visual references are reduced—one of the biggest safety levers in low light
• Builds calm, structured responses to common problems (light issues, separation, disorientation)
• Strengthens buoyancy and control while managing additional equipment and task loading
• Helps you plan more conservatively with clearer decision points and better team coordination
• Makes your diving more adaptable across sites where visibility changes with weather, tides, or seasons

1. Knowledge Development (self-paced): Review procedures, hazards, equipment, communication, and navigation approaches for night/limited-visibility diving. Most students complete this over a few short sessions.
2. Instructor Planning & Briefing: We review your gear setup, light handling, signals, buddy procedures, and the dive plan (including surface interval and no-decompression planning). Timing varies based on experience and site logistics.
3. Open-Water Training Dive 1: A coached dive focused on safe procedures, maintaining buddy contact, effective light use, and controlled navigation in low light. Typical in-water time is at least 20 minutes, with full briefing and debriefing.
4. Open-Water Training Dive 2: A second coached dive that adds more navigation and problem-management practice (for example, reorientation and controlled decision-making when cues are limited). Scheduling is typically one evening, but may extend based on conditions and your pacing.

Required personal scuba gear:

• Mask, snorkel, fins
• BCD, regulator, computer
• Exposure protection appropriate to conditions (wetsuit or skins as needed)
• Primary dive light and backup light
• Audible signaling device (e.g., whistle)

If you don’t have gear yet, we’ll help you select properly fitting equipment and a practical lighting setup that matches where you’ll dive.

Included:

• Private (1 student) or Private Group (2 students) instruction,
• SDI digital learning materials (eLearning or equivalent materials as available),
• training briefings/debriefings, and
• certification processing upon successful completion.

Not included (varies):

• Personal scuba gear (you supply your own or rent; rental availability varies by location),
• location/entry fees,
• charter boat fees (if applicable),
• travel/hotel/meals,
• optional purchases, and
• any specialty equipment upgrades you may choose.

We confirm third-party costs during the consult before you commit.

• Minimum age: 18 (ScubaDives.com policy)
• Prerequisites: Open Water Diver certification (or equivalent)
• Water skills expectations: You should be comfortable managing buoyancy, mask clearing, regulator recovery, and basic navigation with a buddy while maintaining calm control.
• Medical: You’ll complete a medical questionnaire before training. If it indicates a concern, physician sign-off is required prior to in-water activities.

• Is this truly private? Yes. We teach adults in Private (1 student) or Private Group (2 students) formats so your pacing, comfort, and coaching stay front and center.
• Do I have to dive at night? Training is built around night or limited-visibility conditions. In some locations, “limited visibility” may be achieved in daylight if conditions are appropriate, but we plan the safest option for your area.
• How long does it take? Most students complete academics in a few short sessions, then finish the two training dives over one evening or across multiple sessions depending on conditions and scheduling.
• What if I feel nervous in low light? That’s common. We start with clear procedures, controlled pacing, and simple drills that build confidence without rushing.
• Where do the dives happen? We select a site that supports safe entries/exits and appropriate conditions for training. Some sites may have access rules or fees—those details are confirmed during your consult.
• What if weather or visibility changes? We reschedule when conditions aren’t appropriate. The goal is safe, effective training—not forcing a dive.
• What if skills take longer than expected? No problem. Certification is based on demonstrated competence. Additional coaching sessions can be added if needed.
• Do I need special lights? You’ll need a reliable primary and backup light. We’ll recommend practical options based on your dive environment and comfort using the equipment.
• Is rental gear available? Often, yes—but it depends on location. We’ll confirm rental availability and costs before you commit.

Your phone consult is a quick, practical planning session. We’ll learn your goals, confirm prerequisites, discuss local dive-site options, and outline a safe training plan that fits your schedule and comfort level.

We’ll also confirm any third-party costs (site fees, boats/charters if applicable, and rentals) so you can make a clear decision before moving forward.
