XR Foundations Twinset – Build Your Skills This Winter

Your drysuit and dive kit are an investment. Keep using them through winter and take the first practical step towards Extended Range diving.

SSI Extended Range Foundations is the starting point if you have never dived a twinset before. We’ll work through the setup and build your control in shallow, confined water before you move on to further XR training.

Across four training sessions over two days, you’ll develop the skills that make a twinset feel familiar and manageable. Places are limited to four divers, giving everyone focused coaching and time to practise.

Prerequisites

  • Minimum age: 16.

  • Certification: Open Water Diver (SSI or equivalent).

  • Experience: At least 24 logged dives. You should also be comfortable diving in your own kit.

No previous twinset experience is required.

What You’ll Work On

  • Twinset setup: Configuration, manifold and valve orientation, and pre-dive checks.

  • Buoyancy and trim: Stable hovering and a controlled horizontal position.

  • Propulsion: Frog kick, helicopter turn and back kick.

  • Valve and gas-sharing drills: Calm, repeatable responses while maintaining control.

  • Team diving: Clear communication, positioning and awareness of your buddy.

What’s Included

  • Two full days of instruction and hands-on equipment work.

  • Four confined-water training sessions, totalling at least 240 minutes in the water.

  • Twinset hire and air fills.

  • Markethill Scuba Quarry entry for both days.

  • SSI registration and certification when the course requirements are met.

What to Bring

Bring your own drysuit, thermal protection and other diving equipment, along with your dive computer, logbook, food, water and something warm to drink. If you need to rent other equipment, we can arrange it for an additional charge.
