Finally pulled the trigger and will be in northern Florida for 10 days diving with @Trace Malinowski. Any tips to survive his course? Anyone going to be around? Will be there July 16-25th.

Seriously. Don't do it. I don't know how in 3 years of dry suit diving I haven't done it yet, but i've been having a GI bug recently and while diving the other day was farting up a storm. Apparently my "gas" decided not to vent while I ascended because when I unzipped my suit it smelled like...

Heading to Bonaire for the first time this August. Will be staying at Buddy Dive 12th-19th. Just seeing if anyone else will be around. Super excited!

This is the best thread ever. We usually get people who ask "newb" things that would potentially be dangerous but this is one of the first times I've seen someone ask something that if they do it is going to out right kill them (with the exception of that guy who doesn't think O2 is flammable...

Yeah but he said he dives aluminum 80’s with a plastic plate. Those definitely get floaty butt when low. Unless his “physiology” is that of Johnny bravo, probably shouldn’t have a weight behind his head

This argument comes up here once every few months and it’s always the same arguments back and forth. We will never have the perfect study that we want to truly compare these two models. Just like in medicine, many times you have to make due with th studies you have to draw the best conclusions...

I don’t necessarily agree with the one sided test being inappropriate for this study. if their null is that there is no difference in dcs between the two profiles, and they use a one sided fisher and it comes up statistically significant, that should be sufficient to conclude that the deep...

Doesn’t the hog swivel use the same parts kit as the DST? Their second stages aren’t as solid but a hog swivel and a xtx50 might be an even cheaper option

I don’t have any use for these but just wanted to say someone should grab these if they need weights. When I got mine I had to pay around $5 a pound. This is a fair price

Had a bud dive it with double 100’s and two 40’s. With that big of a kit was very underwhelming. He dropped his 40’s and still was underwhelmed. However if you consider the specific advantages this model has in terms of weight price and travel ability, it may be worth it for you. Just have to...

Echoing the above, it is ideal to be cold in the bottom so vasoconstriction lessens your ongassing, and warm at deco so you offgas more efficiently. The active heating is one way to do it. In the Great Lakes up here in cold country it happens naturally. Year round our bottom temps are 40...

K clearly trolling at this point

Are you high? I see patients every day who were on home oxygen when it exploded in their face/nose and they come in with life threatening burns. Oxygen is not safe at all. Where ever we use O2 in the hospital we have very strict rules for handling and fire prevention. The old people on O2 on a...

Watch out for those big cutters. I heard about one guy who used a table saw as a cutting tool and accidentally cut his tank in half while entangled Laughing guy /sarcasm /s eye roll - need to make sure Pete gets it I do believe in small cutters though I have two of the ones Pete linked. When...

Ross, how do those graphs help us figure out where the profile went wrong for him? It shows us max supersaturation but he never crossed critical supersaturation for his profile. How can we use those graphs to figure out where his personal critical supersaturation may have been (in other words...

There’s two competing things: staying deep to keep bubbles small vs getting shallow fast to avoid further ongassing. The sweet spot is about 30ft per minute. That’s for optimal deco though not necessarily to avoid DCS. Up to 60ft per minute although not ideal should still be safe. I doubt his...

Cool to see people do it different ways. I agree realistically it’s not a big deal and is minimal risk. I did learn to do it in and down using a grip that allows a finger to lift the d ring while the rest of the hand/fingers clip it on. I’ll play around with up and out next time to see what all...

The whole point of trim weights is to use a low amount of weight in a specific area to make you "trim out" - be horizontal when neutrally buoyant. Every tank/setup is going to be different in regards to how much and where you need those trim weights. If this tank is a different length/width/etc...

I was always trained to clip bolt snaps in and down so that the opening/lever faces my body, never out to the environment. Interesting to see others were trained differently. I agree up and out is easier to do, but in my opinion in and down with the lever/opening facing you is more protected and...

As everyone has said, wicking layer is super important for cold water diving. I routinely dive in water <45 degrees year round. Do not wear boxers/sweats/underwear/etc. Instead of underwear, buy an undergarment that wicks and only wear that. Then on top, wear your thermals. I wear 4th element...
