I never stated that they way I was trained was standard across the community. I referred to the point that doing a deeper dive, as done in AOW was not necessarily nonsense as argued, but training above the minimum standard was generally acceptable. Take a poll from those certified during this...

I would not identify it as nonsense but rather a type of training that was generally acceptable at the time, that time has long since passed. In my initial dive class some 40+ years ago through an SSI instructor, the focus was on diving within your NDL and nothing about depth and gear...

I completed mine in January 1996 and it was much different than how it is approached today. Several dives and exams. Very few instructors at the time and not many divers using it. I had to drive up to Long Beach from San Diego to find an instructor. The only one I could find close to me was...

I went with both. I use the black one as a primary computer and the blue as a bottom timer/backup

The Halcyon pockets are easily glued on, here is what they look like on my wetsuit and I have one on each side. You could glue on a large patch of velcro felt on the suit and then just stick the pocket (hook side of velcro sewn to back of pocket) in one spot and see how you like it and if not...

It’s unfortunate that more divers in the U.S. didn’t try a Y valve when they were available as they may be rather common today if they had given them a chance. There were a few things going against the Y valve when they were available here. First, they looked odd and most folks don’t like...

I use a Y valve on a single 130 and sling a 40cf pony. Three first stages, three second stages. I dive the same configuration whether diving in 30 feet of water or 130.

cut it off and use some glue to hold the edges or sew it.

I keep the M25X2 valves in case I need parts from them to work on the 3/4 NPSM valve. They are identical except for the thread pattern so the M25 valve can not be used on US cylinders. The 3/4 NPSM valves are very difficult to find. The M25X2 valves are still available outside of the US.

It can be easy to get them mixed up if you don’t verify the thread pattern before using them. I keep a few of the M25x2 valves for spare parts if needed for the 3/4 NPSM valves. While an M25 will fit easily into a US cylinder, you won’t generally get the cylinder filled to it’s rated pressure...

Too many unknown variables to give you a definitive opinion. It may depend on how you dive, where you dive, conditions you may encounter, and what type of diving and gas planning you use. Contemporary computers have greatly improved in reliability over the early examples but like anything, it...

Just bring a full set of gear like you would to any other dive. As most units are geared more towards recovery instead of rescue, put on your uniform, grab your gear and go 10-8. Don’t take for granted that your dive van/trailer will always be available. You should bring enough gear so that you...

Not a huge upgrade so I don’t see many dropping their current model for the new one unless they simply must have the latest model. I already have a metal cover for mine and the buttons are under a silicone cover and I don’t use alarms so I have no reason to purchase the new model. Perdix 2...

Sorry for the late reply, I missed the question. No, it was diving. I have made dozens of dives in that lake. Our dive unit was there to do some work on the dock and film some stuff by the intakes. He has no idea where it might have come off. Guy would come out of a dive and dump wet gear on top...

It’s that initial shot that will get you. Once you are assimilated, it goes down much easier.

Yes it is. I have a couple of them that I use and two extras that are euro models that I keep for spare parts if needed. The cylinders are HP 130s

And their music is too loud and their style of clothes is bad and by the way, stay off my lawn... :) Relax folks, it's all part of the evolvement of the sport and while you might see it as a detriment, newer divers might view it as progress. Like others, I became involved in diving in the late...

You're not watching documentaries, it's just a typical horror film. Same thing can be said about anything involving the military, law enforcement, or any movie using firearms. It's all made up for theatrical affect and much of what you see is not grounded in reality. The problem is folks that...
