Please reserve your non-DIR answers for another forum, your response here has no place in the DIR forum.
If you can't count on someone else being able or willing to help you out if you have a problem, why dive with them? That's exactly why most of us choose not to dive with non-DIR divers, as they won't be able to save us should the s&%t hit the fan. There are people that I trust above water with my life, my best friend of 15 years for example, however, I won't dive with him because he's reckless and dangerous underwater.
I'm sick of all these 5 page threads with more than half of the responses to the questions being from non-DIR divers who give non-DIR answers or non-DIR divers who question the responses from DIR divers. Keep in mind what forum you're in, go to "Basic Scuba Discussions" if you have a problem with the DIR responses to questions that were posted in this forum.
Mods - I challenge you to clean up this forum to keep it the way it was intended, this is ridiculous.
