PADI Cavern Diver - Onkalosukeltaja

Caverns exist in many areas where scuba divers venture – from freshwater springs to volcanic island walls and limestone coasts. In these locations you’ll find large, dark spaces that seem incredibly inviting, yet are potentially dangerous. The PADI Cavern Diver Specialty course gives you the knowledge and skills to explore caverns correctly – allowing you to enter far enough for adventure, but staying within the light zone for an easy exit to open water.

Course standards require you to be at least a PADI Advanced Open Water Diver (or higher) who is at least 18 years old to enroll in the Cavern Diver course.

Please note these extra prequisites regarding Aalto's cavern diver courses:
Due to our country's overall demanding dive environment AND the fact, that proper caverns suitable for this course are situated relatively deep, we require our students to have proper deep diving education (example PADI Deep Diver or equivalent) and have already good skills in buoyancy control and dry suit use. We require our students to show proof of enough cold water diver experience with a dry suit in Nordic waters. Our course location is the Kaatiala quarry, where you can expect the water to be 3°-4°C (37°F-39°F) most of the time, maximum 10°C (50°F) in the summer time at depth.
Proof must be shown on request from logbook/ other records and or an evaluation dive if needed. Expences of the evaluation dive are to be calculated separately depending on the location.

Ready for a challenge?
You’ll complete four scuba dives with the first focused on line handling, reel use and emergency procedures outside a cavern; and the next three dives put your new skills to use inside a cavern.

The main topics of the course:
Other specialized equipment for cavern diving, such as lights and redundant breathing systems.
Avoiding disorientation and anti-silting techniques.
Dive planning, including depth and distance limits and air management for cavern diving.

What equipment will we use?
Along with your basic scuba equipment, you’ll need a primary dive light and a smaller backup light, plus a line and reel. Your PADI Instructor or local dive center staff may suggest other gear appropriate for cavern diving, such as a collapsible snorkel that fits in your pocket or other technical diving equipment.

Kurssilla käytettävät varusteet:
Perussukellusvarusteiden lisäksi (Kuivapuku, aluspuku, hanskat, huppu, avokantaräpylät, maski, tasapainotusliivi, kaasusäiliö, regut) tulet tarvitsemaan päävalon ja varavalon. Lisäksi tarvitset reelin ja laininarua. Muihin varusteisiin tarjoamme mielellämme täällä kaupalla konsultaatiota, tai voit käydä rauhassa kouluttajasi kanssa läpi hyviä varusteita ja shoppailla ne ennen kurssia - hyvä jutella kouluttajan kanssa mahdollisista muista varusteista, jotta hän osaa ottaa niiden käyttöönottoharjoittelun mukaan osaksi kurssisukellusten ohjelmaa.
