Wind chill below 0 degrees F today! Drysuit froze before I could walk 100 feet from the water to my car.

repost of original for comparison

Picture update: tanks at about 1800 psi. Can see with the adjustments I made described in my earlier post, they are much more trim/in light with body's axis. No more issues with valve dangling down and hitting stuff or butt of tank sitting up over the top of my doubles hitting the ceiling in...

Makes sense tbone To the OP: a good example of why you should always test your tanks and not trust the sticker, even with a reputable dive shop... I went to get an O2 fill in a tank recently. Newer employee was there that I didn't recognize. Dropped off my tank. When I went to pick it up...

@tbone1004 Did you mean in the tech world you don't analyze them when you pick them up, or you don't analyze them before you dive? I always analyze all my mixes with my own analyzer before diving to ensure they are what I think they are. If i'm going to die under water, it's not going to be...

I've interpreted multiple posts on here as DCS is "uncommon" and a "minor" issue (because it's so uncommon) and people stating that "a couple of minutes" of deco is no big deal and unlikely to cause an issue. I've interpreted multiple posts on here as stating it's "probably" okay for an OW diver...

I can second south florida diving headquarters for a newer diver/someone looking for easy dives. They have a lot of shallow reef dives and I've dove with them when traveling solo/got paired up with a buddy already on the boat. I used them a bit when I was first certified.

I can agree with this. I just have a hard time drawing a line/figuring out where the cut off is between them. For instance, if people think 2 minutes of deco is no big deal, how about 3? How about 4? 5? 6? 10? where do you draw the line? I just think untrained average OW divers need to...

Except there are people that have blown off "minutes" of deco and had a very serious problem. DCS is never a "minor" issue. Some people with type 1 dcs just need some O2. Some people get serious symptoms and need a chamber. Everyone with type 2 needs a chamber and some people get better and some...

Well I have to respectfully disagree as well. I agree there is a wide range of decompression obligations. I agree that tables differ. However it seems that the large proportion of underwater divers are diving computers, primarily computers with RBGM which is proprietary and we don't necessarily...

So based on your reply, it's happening with many different masks and always from the bottom. Do you have a few masks at home to experiment with? Try that dry land vacuum face test again but with the regulator in your mouth to see if you still get that vacuum seal moving your face everywhere...

You need to do a little bit of a home science experiment. You need to figure out a way to find out where the leak comes from (left side, right side, both, top, bottom, both) to figure out the best way to fix it if no one can figure it out. It sounds silly and don't drown yourself but something...

What an earlier reply said should be true: If you can put it on your face and create a vacuum with no mask strap, and it stays on your face and doesn't fall off moving in all directions, even with your face pointed straight down, you should be good. I would have someone watch you when you dive...

How can you be making an argument about data that no one else has access too/ability to scrutinize and analyze? We are just supposed to take your word that your data shows what you say it shows? At least published peer reviewed data/articles can be scrutinized and discussed by everyone. Unless...

It's like completely horizontal when full now. The problem is it's not uncommon to get an O2 fill around here without a booster so it caps around 2k psi. I wanted to make sure I could keep it horizontal even when around 2k so that it's trim most of the dive. I'll be diving again this weekend...

I thought about doing that but I got it fixed without adding any extra weight to my kit which i felt was better.

Some people on here really need to take a statistics class before they attempt to criticize someone who's life and career revolves around this research...some of the arguments here are covered in stats 101

It seems like our models fall apart for these longer, deeper profiles where this fake "helium" penalty may actually be the thing saving us on those profiles, but for the wrong reason. But what about using helium on shallow dives? Is there truly no difference between nitrogen and helium? The...

So if I'm reading this right, there's thought that there is no true helium penalty in that just because we add helium to a mix, it doesn't necessarily mean we need to perform more deco by adding deep stops for helium which add in more nitrogen tissue on gassing during those stops. But there is...

Agree agree agree. Like a said a few pages ago some of the replies are nuts. Like I said before, people would be going hog wild if someone advocated for "lite" cave diving. There is no lite deco.
