Course overview

The SSI Deep Diving specialty on Tioman extends your safe range to 40 metres, opening up the island's deeper pinnacles, walls and wrecks. Across the specialty dives you learn deep-dive planning, gas management and narcosis awareness on the offshore reef structures that sit below Tioman's shallow boulder gardens.
