And truth be told, I do believe there are certain elements to DIR diving that DO make me a safer diver. Practicing drills will make me better able to deal with an underwater emergency. Min gas vs safety stops seems to me to be a better way to off-gas, leading to lowered risk of getting bent. Propulsion techniques that don't silt up the bottom can lead to better visibility in silty areas. Consistent pre-dive checks mean I'm less likely to forget something important, or find something malfunctioning at depth. Clear, consistent underwater signaling means I can better communicate with my teammates. Can all these elements of increased safety be found in other ways, other dive "philosophies"? Maybe. Probably. But I got them from my GUE class. Why does that deserve to be mocked?
As for applying Hogarthian tech configurations where they aren't warranted - what's not warranted? When you are at my level (recreational) the aspects of it all work quite well together. What's wrong with using it? Does it cause problems? Is it too complex for recreational diving? If so, I'm not seeing that. The can light is probably the most "tech-diver-ish" aspect of it - but I just bought one for myself because I like the idea of it being attached to my hand, so I don't have to hold it...so I have both my hands free. And they sure are excellent lights! So what's the harm in using them for recreational diving?
