Hi,

My friend was planning for a diving discovery package in perhentian. so i have a question, would it be an issue for a person with teeth braces?

Yup, but I just bought new sets of equipments, so I need to do every check and test myself again. And will get advice from instructor. Thanks.

In case an accident happen in deep underwater and I got low on air. Positive buoyancy will not happen. Else.... Hehe. Anyway, still a lot things to learn to pair with my new sets.

Just to inform myself I need to consider the buoyancy while my air is low. Do a weight check on low air tank as well.

Hi guys, planning to get my open water licence in September. Was planning to get it in koh pangan or koh Tao. Which one would you guys recommend?

You can still use releasable weight with a backplate e.g. weight belt / weight pockets.

When I dive with no releasable weight it's an amount I know I can kick up if my bladder fails, and I also keep with me backup buoyancy (SMB).

Wah ~

When wanna belanja me go mexico diving?

whats the point

Or in other way, remove your bcd. Your body itself is naturally bouyant, which is why I always say, if you use a backplate, you have to be very comfortable with it, which means you're not the panicky type of diver, or still very new to diving.

New divers, or those prone to panic, stay with normal jacket style bcd and weight belts so that others can assist you.

almost everyone is trained and certified with a jacket BCD, thus more familiar with the usage. backplates on the other hand, requires different removal style, so your buddy may not be able to assist you

also, with most jackets, you wear a weight belt, so if you remove BCD, you will sink fast, which is why in training and exam, they teach you to remove weight belt first, so you will instantly be positive. with backplate and not wearing a weight belt, removing BCD will make you positive bouyant.

Is positive buoyant good while emergency happen?
I just imagine that if I'm at positive buoyant, I will hard to control my ascend speed.
It was dangerous if emergency happen and panic and just wanted to get to surface.

if I'm in unconscious. then maybe..

i think there are many things that influences a purchase, and checking the lift of a bladder is really, imho, one of the lowest factor for casual divers. note, i use casual divers, who is probably the biggest group of divers. also, how many actually do buddy checks and learn how to remove before dive? yes, i agree this should be a set routine and stuffs, but honestly, most don't. they'll most probably just check air is open, everything is in place and working.

what you are mentioning is probably what should be done, and what is right way of doing things, but in reality, it's not. hardcore divers do that, cos they are passionate about their equipment. I do it as well. i do comparisons of bcd versus others in the market, what features it have, what ease of use it offers, etc...but most people...i like the BCD....i had a friend who bought Oxcheq just because the bladder comes in red...no other reason

Situation I'm thinking here is if the bladder punctures or the inflator elbow breaks... then you'd lose buoyancy from it. If you have no backup buoyancy, then byebye gotta ditch it.

Is better to have a dive trip? 

agree with you, should always spread the safety message. too many ppl in the world with herd mentality, doing things without knowing why they need to do it.

Met a diver from NZ a few months ago, was shocked when he told me that this year, 9 divers died there That's like 2 per month.

Yaya. Agree. I read a lot diver accident lesson for life. Accident happen mostly involve are experience divers.

wouldn't that mean that if you're trained properly, doing all the safe things should be in-grained in you without you thinking about it? like when a regulator is out from your mouth, you will continue to blow some bubbles? or you'll automatically check for air pressure once in a while during dives and not when the guide or DM ask you for it? or you'll automatically do safety stop even when others dont' bother?

that's more of ego problem?
i think being experienced is that you understand the fundamentals of diving, and given any diving conditions, you are able to properly navigate the best/safest way around it? granted, in some situations, need split second decision making, and some might take the wrong decision, such in the case of the Finland cave divers who died in Norway. are they being careless? 'forget' training?

How about a bright strobe light?

I think he meant a safety strobe, not a photographic one. Like this: https://www.divegearexpress.com/tektite-mul...00-strobe-light

Don't think got to turn on while normal diving. The strobe will disturb others. Haha.
