Not sure if this is how I learned the valve drill. Notice the diver not going back to the long hose after right post shut down. he shuts down the Isolator while breathing the necklace (secondary) regulator. Then he shuts down left post while breathing from it while primary is unclipped. I am not sure if this is how it is taught in UTD or there's something wrong here. Because in my GUE fundamentals training we would shutdown right post, check secondary is working , breath down primary and then switch. then we would reopen right post , check reg is working then switch back to it (primary). then shutdown isolator and reopen. while still breathing long hose , we shutdown left post and purge it down and then reopen. then do the flow check.
Hi Mostafa, there are several ways to do the V-Drill, all them prosecuting the same goal. In UTD this is the standard to be all the UTD students in the same page. It looks you did in another DIR agency, but at last, the same results.
