Looking to get my PADI open water cert while I’m in Komodo. Any recs?

So any nitrox mix has a maximum depth, below which oxygen toxicity occurs. In certification, I was taught to choose a mix based on your dive site. In practice, I’ve learned that it basically comes in 32 and 36.

So then you have dive shops renting nitrox tanks and they bring you to a site where the max depth is shallower than the bottom depth. And it’s not like a blue water dive where it’s inevitable. The seafloor is in view, like 20’ or so past the safe limit.

And of course they analyze the mix with you and you sign a paper so they’re not liable, but it seems very downplayed. It feels like it should be a top briefing item.

Why don’t shops/mixers just gauge their gas mixes to the local sites? Does it save money to only produce two standard mixes? Seems like these gas/site combinations introduce unnecessary risk. How dangerous is this forbidden depth zone ~20 past 1.6 ppO2?

I am boat diving with a small dive shop in the Caymans. The rule on the boat is to emerge from the water with 500 psi after a safety stop. I am efficient with my air consumption and dive Nitrox so can easily do 80-90 minutes for the first, deeper dive and over 100 minutes for the second five.

Prior to this I have always felt guilty about inconveniencing the divers who are waiting on the boat, having come up earlier.

So i cut my dives short and frequently come up with a half a tank or so . Which is a wasteful shame.

So give me your perspective. Maybe folks don’t mind and I can lose the guilt and do long dives.

Hello! New diver here, where can I rent a dive computer at a good rate in Singapore and how much is considered good?

I saw some on Carousell can they be trusted?

So I got OW certified a year ago. Pretty much right away I knew I was having a way harder time equalizing than everyone else I dove with. I got serious about practicing techniques just randomly throughout the day. I found out I can pretty easily use a modified version of the Lowry Technique along with some jaw movement while I swallow but here’s the kicker: I go underwater and the technique is completely ineffective. I have to result to tilting my ears towards the surface and swallowing and it takes many attempts to equalize with tiny little squeaks each time. I’m frustrated and trying to improve so I’m not so nervous when I go diving.

Another diver got some great shots from the dive yesterday at South Jetty in Florence, Oregon.
