Diving in the Opal mines of Dubnik
Posted By David Cani & Petr Vaverka on 30 August 2006
Because of this we were just documenting details of the shaft’s exterior, rails and adjacent corridors.
The wooden supports here are in much better condition then in the tunnels at -30m (100feet).
For example you still can see pulleys on beams.
The wall’s colors were changing from red-brown to green-gray until they were almost blue and we were “quietly” astonished by the incredible and amazing scenery.
On the other hand our way back was like a “blind wander” by touch in absolute zero visibility.
But thanks to all of our training, drills and a lot of practice it was not a big deal for us at all to get safely back to the surface in the entry tunnel.
For our dives we’ve chosen as a BG: Nitrox 32 in double sets 2x18L and 2x12L with 80cuft stages. Jakub dove with his rebreather CCR CIS LUNAR.
And we used argon (as usual) to fill-up our dry suits because the temperature of the water was 3st.C (37,4 F)
Our maximum depth for each dive was 34m (112 feet) with a dive time of 70 min.
Over the hundreds of dives on wrecks, in caves, seas or in fresh water are still the memories of atmosphere and experience from diving in opal mines in Dubnik. This still has a first place in my private diving life.
