Report by Alex Boulton, TDD Technical Consultant, PADI Asia Pacific
Just finished teaching PADI Examiner Thomas Knedlik the final level of the new Tec Diver course – Tec 50. The depth requirements of dives 3 and 4 allowed us to take in two good wreck dives off the New South Wales coast –the Deewhy Ferry and the Meggol.
Tec 50 really allows the diver to refine foundation skills – one handed staging & retrieving, efficient cylinder movement between two deco mixes & stage positioning option. It’s obvious that returning to the limited open water really locks in the skills learnt on Tec 45 & Tec 50. In terms of muscle memory these are perishable skill sets & if you don’t use them you lose them.
On dive 3 Thomas had the opportunity to role play emergency drills within the context of simulated decompression. We practiced lost gas scenarios where the diver returns to the staging point to find deco mixes have gone. We approached this with two methods; firstly we responded by both breathing from the single team stage completing decompression and then passing off the mix to the OOG diver & then as an alternative approach on the shallower stops we ran the simulated deco while buddy breathing. This really sharpens the awareness of what is the best option in terms of gas supplies available & the influence of conditions on the day.
