Here is my suggestion on weighting. Go to the local lake with all your gear on and jump in with a tank at around 500 psi or less. Add or subtract weights until you are neutral at 10 feet with lungs about half full of air. When you exhale completely you should start to go down and when you...

Brand names in scuba are not necessarily as helpful as you might think. The company which makes the best bc for you might not make the best regulators or fins or mask for you. When you go with specialized equipment, the company may only make a few things. For example the company that makes my...

I've never gone skydiving but I wonder about what counts as a "diving related death". I wouldn't imagine that there is a lot of physical exertion on a normal civilian skydive that could cause a heart attack for someone who is out of shape. On the other hand, scuba allows an out of shape person...

Ok, I'm making this suggestion based on my experience with hog harnesses and not the dive rite adjustable harness.... I might consider separate harnesses for each backplate. Having to take off a harness from one backplate and put it on the other and vice versa over and over again depending...

On technical dives it would be my air consumption and how excess decompression can be a factor as I plan my dive and dive my plan. On recreational dives it is usually my NDL. However it can be a buddy if the buddy is an air hog. I've also aborted a dive because I got too cold. One other...

In answer to the OP... From what I remember my "junior" card worked as a regular open water card for many years after I turned 16. I told the dive operator my age and there was no problem. Nobody made me dive with my dad when I was 16 and holding my junior open water card in my hand...

Very different class than regular nitrox. This is typically taken with deep air in some sort of tech lite or intro to technical course. Gas planning is involved as is decompression diving. Typically this involves the use of EAN50 where the diver switches to this tank on the way back up from a...

Equipment needed for doubles: Doubles setup with din and isolator valve backplate and bladder for doubles - I dive wet so I use a 55 lb dual bladder oxycheq wing two first stage regulators, din configuration on the left first stage you need an spg on a high pressure 24" hose, an inflator...

I had a reverse sinus block that was not painful, but resulted in an explosion of pressurized snot shooting out my nose and coating the window of my mask. I take sudafed now before dives and have not experienced any ox tox issues even at 1.67.

Maybe the one I saw was a Dive-Rite which is no longer being made. I think - been a while so I'm not certain - that it was cut in a little bit like on a nomad rig. Is this what the dive-rite version looked like?

I've seen the oxycheq butt pad that hangs just below a backplate for carrying a smb and an emergency signal. I've been thinking about getting something like this because I currently have mine bungeed to the side of my backplate. This seems to work ok except for the fact that once I pull the...

I too have allergy induced asthma. I might be concerned about people who have activity induced asthma during a heavy swim. I've told my allergist that I am a diver and he doesn't have any problem with it. My greatest asthma and diving related fear is that my tanks could be filled next to a...

I'm partial to my Zeagle Envoy deluxe regulators. I've tried the Apex regs you listed and they were quite nice, but my dive shop doesn't sell them. I've had Sherwood, but not the new one. One other thing... keep in mind that if you are diving deep with doubles (tech) you are more likely to...

There are several types of bc configurations for diving: 1. Horse-collar - generally an older type that requires a separate plate (usually plastic) to hold a tank. Could be possible to use doubles, but I haven't seen this configuration personally. Mostly now seen with retro divers or as...

I think the deepest open circuit dive was around 850 feet in the Red Sea. This was done with a team of support divers, specialized gas mixtures that you would never encounter in recreational diving and lots of careful planning. Although you can obviously dive below 250 feet on open circuit...

I get a paranoid narc where I must check my dive time, depth and air consumption about every 10 seconds. I guess this would fall into the first category - except that this isn't really such a bad thing, just a little unnecessary paranoia.

Hi. I have a couple of questions about the unit. PPO2 monitoring is extra and comes with CO2 monitoring correct? Must I use the order the O2 monitoring cells from the specific company or could I use cells ordered from oxycheq that work for inspiration rebreathers? Do you have a kiss type...

Thanks for the input. I hadn't run the numbers when posted regarding deco mixes. Mostly I was wondering about the current and whether a port to starboard or vice versa swimthrough of the hangar bay is possible without wreck penetration training. If it is a silty maze in there I'm certainly...

Hey guys. Have a few questions. Here is the scenario: I have the option of driving from Houston to Florida in a couple of weeks for an oriskany trip. I've been told that it would be one dive per day as the boats are generally small and we would all be bringing either twin-sets and Al 80's...

I emailed the guy at Jdeco and the problem is now fixed for the Blackberry 8703e It works just fine on mine.
