air

I have my open water certification but haven't used it in a year. Going to do my refresher tomorrow! Also I made an app to calculate approximate air time based on a few inputs if anyone finds this helpful: https://tank-air-time-calculator.herokuapp.com/

Hi all, I looked for an answer about this topic all over but it seems that this has been discussed a lot regarding recreational scuba, but not so much when talking about technical diving. I read, for many that a solution is always to check in the bc and just rent, but this is not an option. I...

- this sentence is visible in many materials. I am curious what if we breathing with Trimix 19/30 on the surface, do we exhaled 15/30? We reason why I ask this question on the rebreathers group is that this divagation is connected with adding air to the circuit on different depths. Can I...

Hello everyone! I'm new to the forum and I'll inaugurate my first post with a somewhat silly (or not?) question, so indulge me. What if I bought a Yong Heng compressor (around $250) and connected to it to a filter like this one...

I'm trying to improve my air consumption. I'm always the air hog and the dive ends because of me. I usually do breathe from my diaphragm and I try to slow things down as much as I can, but I was reading recently some tips and ran across this aritcle on scubadiving.com which says: Pause after...

Hey everyone I’m just having some problems with changing the gas to air on my i750tc. Under the “Set Gas” screen next to Gas 1, I cycle through the options and it jumps from 100% to 21% which is skipping the “air” option which should be between the two. Has anyone had this issue before? What...

I have a regulator that is only a couple years old. I had yearly maintenance done on it last fall. I tested it on a tank yesterday for the first time since getting it back from the shop and it'll make a hissing noise like its leaking air, then all of the sudden i hear a pop, and then it stops...

When I started diving (10 years ago) I purchased solid (ie. no flexible rubber sections in it) fins. I was in the dive shop a few days ago and was looking at all of the modern fins with flexible rubber sections in the middle and all sorts of advertised advanced channels. Is it worth upgrading...

Hey guys, I'm new to diving and I was out today diving up and down the beach on the naval Air Station I'm stationed at, and I was about 5 feet under looking for shells for my wife. I bumped my secondary regulator and air started blasting out of it. I went from 2500 psi to to just under 1800 psi...

Hi all! I have a paramina typhoon compressor with 3 filling hoses. The way that i have been filling until now was to let the tanks fill up to the compressor limit, then the compressor stops, the tanks cool, the compressor then tops them up a bit etc etc. The other day my instructor informed me...

Hi! I wish to go over from a traditional backplate, harness, wing, twin set setup, to a sidemount configuration. The freedom of movement and the seemingly constant perfect trim, non-dependent on the orientation of the diver, looks incredibly appealing. I'm going back to Bali, Indonesia, for 2...

I'm having some troubles with reception on my Luna. I've done some searching and have seen other with issues but they always seem intermittent and don't include some other things I've noticed. tl;dr; on a recent trip my Luna lost signal quite often. On some dives it was constantly, even with...
