Top rated Semi Dry Suit with Hood. 8/7mm and integrated hood makes this one of the warmest wet suits you can buy. Size Large. Excellent well cared for condition. Used 2 times for 5 dives total, all fresh water, washed with wet suit shampoo after each use. About 4 years old, always stored...

I've screwed the wireless transmitter into a HP port using a little grease on the o-ring like a normal HP hose. Do I need to do anything else? The manual doesn't address installation. TIA!

Cold water, physical effort and fatigue, anxiety possibly related to sensory limitations are all known or highly suspected risk factors for increased nitrogen narcosis. Increased narcosis in my mind means more of a chance for things to go wrong. I am aware that many of the old school air...

In DAN's Alert Diver magazine a few months ago there was a debate about the deep stop. In the end, I think the advice given was if your computer says to do it then do it, if not don't worry about it. Now that I think about it that's a good way to gather more statistics if I were DAN, lol. But...

If you consider that this computer will make an excellent back-up computer when you are ready to buy something more expensive...I'm not sure how much of a mistake it is :) You have the whole Aeris perhaps Oceanic lines to choose from which will be similar to you. For instance, I just bought...

Since I've been thinking about the SS1 for awhile, I practiced last time out keeping the inflator in my mouth and dumping air. If anything, pulling the dump pushed the inflator into my mouth more. Anyway, different configs and practice, practice, practice... The reason I went to shoulder dump...

Here's my $.02: Buy a Worldwide brand for your electronic or mechanical life support. You may need parts or service out in the middle of who knows where. Aqualung, Scuba Pro, Oceanic, Mares, Cressi and their sister companies seem to be pretty universal from where I've been. That's not an all...

Just pull on the inflator hose, use the shoulder dump, assuming your BCD has 1. I use my shoulder dump almost exclusively, and I have an Octo but about to have an SS1.

I've been reading a lot on this topic, both the research and accounts from the pioneers of wreck and cave diving. It seems that while depth is being treated as a primary consideration, water temps and the variables which make up the challenge of the dive are just as important if not more so. A...

My Oceanic Veo 200 is pretty liberal compared to others I've dived with. I just bought a VT4 AI which has user selectable algorithm models and conservative/liberal mode so I'll get a direct comparison using the VEO as back-up.

I was on dive 30 something, AOW certed and with my own emergency second air supply before I went on a dive without a DM, Instructor, or trusted buddy whom I had dove with several times before. I just think there were too many unknown variables here for a 7th dive.

Undercurrent recently published an article on BCD emergency breathing, and how to disinfect your BCD. Based on all available evidence, this one seems to be something that might be a last resort option but you probably should not practice it which means you might get it wrong when you need it...

Just a suggestion also, there are Oceanic authorized online retailers with new "old stock" Oceanic Delta 4/FDX10 with full warranty for $350 shipped, that includes your maintenance parts. If you have not, do a search on the cold water certifications of this combo you'll probably be impressed...

Here's a few add-ons I've noted in my own wish list: Personal Locator Beacon or Nautilus-like GPS/Radio add-on Sonar add-on External Camera/Light add-on

OK, so recommended but not required. Thank you all for your guidance. :) Now for my opinion. Honestly, 4 hour classroom session on administering Oxygen? How about an e-course on the theories and 30 minutes of the Rescue Diver class devoted to hands-on practice. We did CPR in about 2 hours...

I've completed my AOW, have 50 post-certification dives, and taken the Red Cross course on CPR, AED, and Emergency First Aid. The dive shop states the oxygen provider course is a required pre-req to Rescue Diver, while PADI's website states it's a recommended course after Rescue Diver. I...

The 8mph was an example based on the science of a particular situation, not an absolute. Sorry if I was unclear. I agree with everything above.

2008 German Autobahn (no speed limit for most cars) deaths per billion vehicle kilometers = 2.2 2008 United States Interstates, same statistic = 4.5 http://www.internationaltransportforum.org/ Sorry I broke my promise but others apparently want to discuss. Now what is it you were saying?

For those interested, read up on the 85th percentile rule for setting speed limits and the Solomon curve. I don't want to post links on these topics since there are thousands on Google. In many ways you are right, it's not speed that kills rather speed variance. However, the 8mph I referred...
