Train as a TDI Sidemount Diver over two days in the Hauraki Gulf. This practical, skills-focused course mixes eLearning with three tank dives and teaches side-mounted cylinder management for technical and recreational divers.
More ways to explore the area's outdoor wonders
You surface from the second dive with salt in your hair and the Hauraki Gulf stretching silver toward Rangitoto. Alongside you, cylinders ride at your hips instead of your back—balanced, familiar, and suddenly liberating. That shift is the point of the two-day TDI Sidemount Diver course: to reconfigure how you move underwater and expand the sites and profiles you can manage safely.

Complete eLearning Beforehand
Finish the online modules before day one so in-water time focuses on hands-on skills and dives.
Bring or Reserve Your Sidemount Kit
The course asks you to bring your own sidemount gear; reserve rentals in advance if you can’t bring equipment.
Watch Your Flight Schedule
Avoid flying for at least 48 hours after your final dive to reduce decompression risk.
Build Buoyancy Skills First
Good trim and buoyancy control make sidemount transitions smoother and reduce stress during confined-water drills.
Personal sidemount harness and cylinders
Sidemount-specific kit ensures optimal fit and familiarity during skills work and dives.
Dive computer
Tracks no-decompression limits and is essential for planning multi-tank training dives.
Exposure suit (3–5mm or drysuit depending on season)
Keeps you warm during long surface intervals and improves comfort underwater in New Zealand’s cool waters.
Mask, snorkel and fins
Personal fit matters for comfort and performance during surface swims and gear-drill practice.
