Technical diving skills- Ascent rate practice, decompression course

Breaking the recreational diving habit of ascending slowly takes time. On my decompression courses we practice ascending at 9m/min to the first gas switch, then 6m/min up to 9m, 3m/min up to 6m, and then 1m/min up to the surface. You need to have the required control before doing an actual decompression dive. Creating shortcuts if students struggle to control a fast enough ascent rate is not training them how to deco dive. Ignore the ascent rate on the OSTC in this clip, it's incredibly sensitive and useless. In fact, ignore any ascent rate on any dive computer. Instead, look at a stopwatch and use your brain. It takes 30 seconds (slightly less in this attempt) to go from 9m to 6m. In this video, as it was a shallow-ish dive we are practicing 6m/min up to 6m to get it right, then on later dives added in the 3m/min. But remember, some divers go 10m/min all the way up to the surface (often in the US), some do 9m/min up to 21m and then 3m/min up to 6m. Whatever you do, do it by timing it rather than relying on the innacurate ascent rate speed of your dive computer. Diving out of Alba Dive Tulamben in Bali, Indonesia.
