Training with Nanaimo Dive Outfitters gives you real experience in the cold, clear waters around Nanaimo and Nanoose Bay, which are ideal for learning proper dry suit technique and building confidence that transfers anywhere in the world.

Inside your Dry Suit Diver training experience
This specialty includes a brief classroom session at the shop, dry land practice, and two open-water training dives. The course is focused on helping you become comfortable, warm, and stable in a dry suit, even if you’ve only ever dived in wetsuits before.
A typical schedule includes:
-
- Classroom learning on suit types, valves, seals, undergarments, maintenance, and emergency procedures
- Dry land practice with donning, valve operation, trim adjustments, and proper weighting
- Open-water dive 1 covering buoyancy skills, inversion recovery, and dry suit handling
- Open-water dive 2 focusing on controlled ascents, emergency practice, and real-world diving scenarios
This combination builds safe habits and long-term comfort with dry suit diving.

Dry Suit Diver Course FAQ
How different does a dry suit feel compared to a wetsuit?
A dry suit feels more buoyant and bulkier at first, especially around the legs, but most divers adapt quickly. After a couple of dives, the added warmth and stability usually outweigh the learning curve.
Is it normal to feel nervous about uncontrolled ascent risks?
Yes. Almost every new dry suit diver worries about going feet-up. The course teaches controlled drills so you know exactly how to recognize, prevent, and correct inversion long before it becomes a problem.
How much extra weight will I need when switching to a dry suit?
Most divers add several extra pounds because the suit, undergarments, and air layer increase buoyancy. Your instructor will work with you during a proper weighting session to fine tune this for your body, suit, and gear.
Should I buy a dry suit before the course or rent one first?
If you’re unsure which style fits your needs, renting first is smart. It lets you compare sizing, materials, and valve placement before making a major investment.
Will my fins work with a dry suit, or do I need new ones?
You may need fins with larger foot pockets because dry suit boots are thicker. Proper fit matters, especially since a dry suit shifts more air toward the legs.
How do I know if a neck or wrist seal is too tight or too loose?
A seal that leaves deep marks or headaches is likely too tight. A seal that flushes water or slides when stretched is too loose. Your instructor can assess fit during the course.
Can I wear heated vests or other battery-powered layers once I’m certified?
Yes, many divers use heated garments for long or deeper cold-water dives. Training helps you manage buoyancy changes from different layers safely.
