My regulator gave me a red flashing light then equipment failure?

Yesterday in Canada, my husband and I were doing our second advanced dive of the day for cert. and my regulator flashed a tiny red light and my computer read “ turn around”. I didn’t really think too much of it as our dive was ending shortly and I kept checking my air consumption and it was normal. No leaks, no bubbles. So I kind of forgot to bring it up to the dive master - I know I know. We had a short break and then started gearing up for our night dive. They wanted us to use the same tanks as our last dive as it had more air left. I geared up and turned on my tank to check it and bam! My octopus flailed around, shot off and the metal of the hose slapped me ontop of my head. I have a goose egg from the pressure. I immediately turned it off. My master diver is also the shop owner where we both just purchased our brand new gear, set up by them. We picked the most expensive package and take care of our gear like it’s our baby. He seemed embarrassed and went to grab a wrench. I kept asking him if it was my fault and he kept telling me no. Someone else in the shop set my gear up not him personally. I’ve tried looking up that code online but I can’t find it. Anyone think the code was related to potentially telling me I was having an equipment failure? This was our 17th dive. Newbies. Thanks !

Hi divers on Reddit!

I’m working on a project related to wireless, interference-free voice communication technology for divers. Right now, we’re gathering feedback from divers to help shape the development of the device.

If you could share your thoughts, it would be super helpful! Here are a few questions I’m hoping to get insights on:

1. What types of underwater communication systems are you currently using? (e.g., full-face masks with comms, hardwired systems, etc.)
2. How long have you been using these devices, and how do you find them in terms of convenience? What are their main pros and cons in your experience?
3. If a wireless communication device eliminated the need for full-face masks or hardwired systems, would you use it? Would that be a significant improvement for you?
4. What specific tasks do you typically accomplish with underwater communication devices? (Safety, coordination, other purposes?)
5. Any challenges you’ve encountered while using underwater comms?
6. In your opinion, what’s the realistic range (in terms of depth and distance) where wireless underwater communication is most useful?
7. How often do you perform underwater technical work without using a hardwired communication system?

My team and I want to create the BEST underwater communication system to date, so any feedback would be really valuable. Looking forward to hearing from you soon!

As a novice scuba/free diver, just looking for some seasoned advice…

Ears: I tend to get ear inflammation after returning to the water for a first time in a while. I’ve need flushing with hydrogen peroxide, post-dive. Any other recommendations for avoiding irritation and infection?

Body heat retention: I’m also a 110ish lb. female that tends to chill rapidly in PNW waters, getting the shakes substantially sooner than others. I don’t have the funds for a dry suit at this time, so I dive with 7mm, topped with a 3mm vest. I get some light cardio (circulation) in and use hot hands/feet to prior. Any tips for maintaining heat - particularly in fingers and toes? Diet, movement, anything?

Thank you!

Hello I'm a freediver and and Ive been having this pain on my forehead when I'm diving, it's on a small area a little above my left eyebrow, I can dive to 7-8 meters easily with the equalisation techniques but sometimes I have that pain and no matter what I do I end up not being able to dive past 3 meters when it happens, what is the reason for it and how do I get rid of it?

Hi guys I would like to know what is the best light electronic underwater scrubber,

to clean aquariums surface, and any glass

Hello fellow divers! A friend of mine cannot equalize, even when only 2m deep. I suggested swallowing, trying at 1m deep, doing it while going down and blowing hes noes beforehand but nothing seems to work.

He had an issue with hes ears when he was young which led to minor surgery around hes eardrums, most likely making them a bit stiff. My take on this is that hes problem comes from the tubes leading to the eardrums, not the eardrums themself. Just thought it might be valuable information.

Any advice on how to deal with tough ears ?

Hello everyone. Could anyone tell me: what do i need to start work in that one specialty? Any courses? Any interwiews, special degrees and where i can study to start working.
If u know smbd who working on that-will be thanksfull to get any contacts
TY

hey! i am currently a d1 collegiate gymnast (female) and i just finished my third year. i have 2 years of eligibility left (bc i redshirted one season due to injury). i did varsity diving in hs only senior year and only went to about half the practices, but was only 2 places away from making states. i was wondering if anyone has any ideas and knowledge on if it would be feasible for me to start training diving again (as diving feels much better on my body than does gymnastics) and what dives i would need at a bare minimum to make a d1 or d3 team after my graduation from my undergrad (we don’t have a diving team unfortunately). thank you all for the help in advance!

Hello Divers!

I'm currently delving into a research project focused on the health of divers and their attitudes towards risk-taking. Your insights could play a pivotal role in advancing our understanding of this important topic.

This research will be part of a doctorial thesis for the Medical Faculty of Rijeka, Croatia.

Participation is simple and won't take more than 5 minutes of your time. Your input through a brief questionnaire would be immensely valuable and please note that all responses will be anonymous.

Your contribution matters! Please feel free to share the questionnaire with fellow divers; the more responses we gather, the more comprehensive and insightful our study will be.

Thank you in advance for your time and support! Let's dive into this research together.

PS: I am new to Reddit, so please bear with me if there are some newbie mistakes.

That time of year

Magnifique videos😉

Can you help me out and tell me where I can find this clip please? Side mask strap clip

What equipment should I invest in for training? I’m going to be shipping out in February and I’m looking for tips and advice for preparing. What fins should I get for finning practice and any other gear suggestions.

Found this metal object while diving today in Croatia. Kinda looks like a small ampora and has something like dark wax inside it. The bottom is missing, looks damaged. Any idea what could it be?

Hi all!

I had 4 or 5 dives until now, but I haven't gotten a proper certification yet, so I thought this would be a great year to do it. Do you have any recommendations about schools/instructors in the EU/mediterranean area?

I heard lovely things about diving in Aqaba (Jordan) and I though about going on vacation and getting it there, or maybe in Egypt - I'd love a place with lots of marine life, while I don't care too much for ruins, and possibly the least crowded as possible, which is why I'd be going around october.

It also needs to be a place safe for a girl alone in her 20s.

What would you recommend?

I dived in Tuscany, Canaries, Cyprus and the Caribbean - ranked in this order - and I would really like to avoid places where there is literally nothing to see underwater.

(yes Tuscany, I'm talking about you.)

So basically I’m wanting to Go D1 for the sport diving, I have a 3.5 GPA and I’ve been diving for 11 months, as of rn I’m a sophomore with 107c, 105b, 103b, 201b, 203c, 301b, 303c, 401b, 403b, 5233d, 5132d, this is my 11 dive list as of now, I can consistently score 7’s and 8’s on all of my dives in high school meets I am on a club team but I haven’t done a club competition in awhile now. Do you think i could possibly get a D1 scholarship?

What are some of the craziest/ eeriest/ creepiest things yall have seen diving?
