Guided flooded section (max 21 m) / technical overhead site: operator zone [1] (The operator separates guided dives in an open flooded area from technical overhead diving for cave- or mine-trained divers.). Estas categorías pertenecen al esquema indicado; describen la formación que requiere cada sitio.
The diving base of the Tuna-Hästberg visitor mine, about 80 m underground, serving both guided dives in an open flooded area (to about 21 m) and technical overhead dives on more than 7 km of permanent line.
Divers walk about 80 m down through the old mine to water level, while equipment is sent down by lift or carried on the former mine railway and then about 300 m to the dive site. The technical site has a warm room, changing area, dive platform and compressor with gas bank.
Guided dives in the flooded open section are capped at about 21 m and about an hour, and groups of 1 to 16 divers can be booked. Technical overhead divers use the permanent guideline network deeper in the mine.
El entorno
Cold (about 4-5 °C), very clear mine water in tunnels and flooded chambers of a former iron mine.
Condiciones
Stable conditions year-round; operator states visibility at the technical site is always over 30 m.
