Extended Range

Extended Range

DaivoonTec, Lanzarote

where technical diving truly begins.
Designed for serious divers who want to go deeper and stay longer, this program trains you to conduct limited decompression dives up to 45 meters.

Start your journey: Entry level tec courses

With six open water dives, extensive in-water practice, and a focus on safety and redundancy, you’ll be prepared to take on complex dives with confidence and control.

During the course, you have the option to complete the final two dives using either air or trimix.
Trimix offers better clarity and reduced narcosis at depth—ideal for sharper focus and safer dives.
Air is a more cost.
The choice is yours—performance or practicality!

Twinset

Twinsets are the traditional backbone of technical diving. With two back-mounted cylinders and a manifold system, they offer a symmetrical, solid setup that keeps your trim stable, offers unparalled balance and gas management straightforward.
Perfect for divers who prefer a single unit on their back and want seamless access to both tanks through the manifold. Also has less of a learning curve from traditional single tank recreational diving.

Try Twinset

Sidemount

Sidemount offers a more flexible and modular approach—cylinders are mounted on your sides, reducing strain on your back and allowing easier access to valves and hoses.
It’s ideal for tight spaces, like caves or confined wrecks, but is becoming more popular in Open water aswell. However Sidemount requires prior knowledge and certification for the Extended Range course. If you don’t have a Sidemount certification an XR Sidemount course is the perfect start!

Deco Sidemount

  • Max Depth: 45 meters
  • Decompression: Up to 25 minutes of accalerated decompression
  • Deco gases used : Up to 100% O2. However mostly EANx 50

  • Equipment: Twinset or sidemount with extended range configuration
  • Stage Deco Diving: Decompression planning is practiced, and executed during training dives
  • Goal: Skill development, planning, and configuration – proper 45m deco dives
