SDI Night and Limited Visibility Diver Certification in Nanaimo
Discover a new side of Vancouver Island diving after dark.
Night diving is one of the most rewarding experiences in scuba. Many divers say it becomes their favourite type of diving once they try it. The SDI Night and Limited Visibility Diver course teaches you how to dive safely after sunset and in low-visibility conditions while helping you explore the nocturnal marine life that only comes out at night.
Training with Nanaimo Dive Outfitters lets you experience night diving in one of the richest cold-water ecosystems in Canada, with safe shore access and predictable conditions perfect for learning.

Night Diver Course FAQ
Is night diving safe for newer divers?
Yes. As long as you have solid basic skills and good buoyancy, night diving is very controlled. The course is designed to teach you how to stay oriented, communicate clearly, and manage light-based navigation.
How dark is it underwater during a night dive?
It varies by moon phase, cloud cover, and depth. In Nanaimo, true darkness begins within a few meters of descent, which makes proper lighting and navigation skills essential.
Do I need my own dive light or can I rent one?
You can rent lights from our shop, although many divers prefer to own their primary light to ensure familiarity with the controls and brightness.
How long do the night dives last?
Typically 20–45 minutes depending on conditions, temperature, and student comfort levels.
What’s the biggest challenge for most students?
Staying relaxed. Once divers adjust to the darkness and trust their lights, the experience becomes calm and enjoyable.
Will night diving help my overall skill development?
Definitely. Many divers report major improvements in buoyancy, situational awareness, and navigation after taking this course.
What kind of primary light should I buy for night diving?
Look for a bright, narrow-beam light with a simple switch you can operate in thick gloves. We can help you choose one that fits our local conditions.
Can I take this specialty before other advanced courses?
Yes. As long as you’re an SDI Open Water Diver or equivalent, you can take Night Diver at any point in your training pathway.
