Kingston, Lake Ontario for a challenging weekend of diving continuing our advanced diving courses - deep, wreck and night diving. The conditions are tough - low visibility and cold water, but with the right gear the temperatures were tolerable. In the cold deep lake water the wrecks are uniquely preserved as compared to many other areas in the world. One such was a double paddle wheel steamer whose paddles were still predominantly intact. Deep and wreck diving is a real mental challenge for me to overcome. Wreck penetration was the plan for our last dive, but we never got to practise that skill with the separation of the group down there. It will take more practise and experience for me to feel more comfortable down there, and before entering an enclosed space at depth ! Needless to say my air consumption is above average but that should improve with experience. We are told often the high quality of experienced Canadian divers - I am not surprised with the local conditions they dive in. Not only do the advanced courses help our diving skills, our thoughts are that it is great preparation for a planned diving trip to Mozambique in late October.
