Hey peeps, I recently started to get to get wet when I drive with my dry suit. So this morning I took everything apart and sprayed it down with soapy water. I noticed that when the zipper was closed at the very end after closing it there were small bubbles. I would rather not replace the whole...

I am going to get them tumbled. Thanks everyone for your input!

in the future i will be more careful but right now i am just wondering if the tanks should be/can be saved.

I have about 10 other steal tanks that have never had any rust... but these are the ones i use the most and travel with the most.

They get filled everywhere from Florida keys and cave country to SoCal... so i have no idea where it might have happened...

:rant: fing keyboard...

does that mean you would just get them tumbled?

I have 2 steel 100s in a double set. Both tanks got some salt water sprayed in them and now have some surface rust on them. I think it is surface rust. I only found the rust when they got back from hydro which they passed. My LDS is telling me i should just trash them and get 2 new tanks...

Hopefully someone on here can help me out with a question. What is the difference between the 2 first stages pictured below. can are the face plates interchangeable? My wife would REALLY like the purple insert for the new one but she only has the old style(Like the second image).

I would like to make a gift for a friend of mine but need a tiny bit of help. I would like to make some custom winter or urban camo elastic bands for his perdix computer. I know the bands are about 19 cm lying and about 3/4 inches wide but I was wondering if anyone knew where I could get high...

I think i also read some where there are major issues with effort of breathing... moving liquid is WAY more work then moving air. We have issues moving "thick" air at depths.

Guys thank you so much for helping me understand this. does this mean that as we dissolve more O2 in the blood the venous saturation is going to increase as well? i think someone else said that the metabolic rate at which we use o2 is not pressure dependent so we would use the same about no...

Thanks so much guys... i will try that as soon as i can get back to him... I honestly had no idea that a usb to cellphone connection would even be possible... it is not quite as soon as a laptop but it will do and it is FREE so that is even better!!!

that is a super interesting idea that i had not thought about... if you need about 3ATM of O2 for that to be the case does that not happen around 66fsw? isn't that about the max depth for 100% O2?

So does the hemoglobin get the O2 from the dissolved O2 in the plasma? Cause it sounds like there is not much 97% in the hemoglobin vs 3% in the plasma? or does it just dissolve super fast from the air to get absorbed by the hemoglobin. I know that lungs have a ton of surface area to make this...

Ordered that book an amazon. Looks like a good read.

I feel like this can be avoided/mitigates with knowing your equipment even if it is a set of rented regs as well as going with a reputable dive shop that is not going to rent out a bad set of regs. It may be be 100% avoidable but i think it should pretty close to that with a tiny bit of prep...

if the hemoglobin carries x amount of O2 at 1 ATM does it cary 2x at 2 atm? or is that just the dissolved gas

The Quiz from Thursday got me thinking and i would like some help understanding something. We breath and atmospheric gas gets dissolved into our blood(the liquid/water part) according to Henry’s Law and Dalton’s Law. But this is just the liquid part of the blood. Do the red blood cells and in...
