Blades,
You misunderstood my post. We NEVER do entanglement training in open water. Ever. Our entanglement drills are safety divers cutting people free.., which is simulated, with no diver ever being actually entangled in open water.
We do everything with safety in mind..., thus our rather extensive training regiment which has received praise from a large number of dive teams in Canada, the US and literally around the world. We do our drills with the most realism we can muster in a safe environment. We NEVER black out a mask because from our position, any diver needs to be able to monitor his/her guages. The ol' "WE dive where you can't see your guages" arguement was tossed out with us because we do that too. We just decided in the interest of safety we studied it, researched it, consulted with 'experts', developed and modified our training and now if you can't see your guages, our guys go SSAD. Always.
We do 1000's of PSD dives per year, have an outstanding program that is the envy of many and we are continually striving to improve.
DRI has a good program.., but so do we.
