Snorkeling and Scuba Diving… info please?


Okay so this may seem a little unusual to ask but if i cannot swim, wouldnt it be a good idea to go snorkeling or scuba diving? i would have someone with me who knows how to swim but i would have though it would be easier as you wear you have an oxygen tank on your bank therefore you wouldnt panic causing yourself to drown? or am i wrong in thinking this?

Speaking as a former lifeguard, and SCUBA instructor, I would strongly recommend you learn to swim properly first, before trying either of these two activities. Both require one to be comfortable about being in the water, including getting one’s face wet, which is not the case for most non-swimmers (and even doggy-paddlers are pushing it).

Although no certification is needed to go snorkelling, and wearing a life vest will stop you from sinking, that may not be enough to enable you to enjoy it. And since that is the whole point of any recreational activity, there is little to be gained from doing so, apart from stress (both for you and anyone who goes with you).

This applies to an even greater extent in SCUBA diving, which has a far higher risk index, including factors that non-divers (and even some entry-level divers, in my experience) have difficulty comprehending. Any diver without a supervisional diving qualification (e.g. PADI Divemaster equivalent or better), who would nonetheless take his non-swimmer friend diving, is destined at best for a stressful experience (for both parties) and at worst, a serious accident, with the accompanying guilt and/or lawsuits (or even criminal prosecution, if the accident is fatal).

One of the prerequisites for becoming certified as a scuba diver is being able to swim, and under PADI standards one of the ‘medical contraindications’ (i.e. absolute no-nos) to starting a course is ‘to overcome a fear e.g. of the water’. No professional instructor (professionalism being defined in terms of ability, knowledge, responsibility, and ethics, rather than simply ‘paid’), regardless of agency, would certify a total non-swimmer to dive.

Having said all that, subject to successful tryouts in standing depth first, I have taken non-swimmers for shallow intro-dives (no certifications issued) in sheltered open water. I had to do everything for them except breathe, but that’s OK, because they enjoyed the experience. However, this very much depends on the individual (both diver and instructor).

Why do scuba diving pressure gauges reach 5000 psi if a tank may only be filled to a max of around 3200?



Scuba tanks can be filled well past 3200psi. When they do a hydrostatic test it is well beyond any pressure that any dive shop will fill a tank to. The highest I’ve seen the pressure get in my tank is 4000 and that is when the filler at the dive shop forgot about it.

Scared to go scuba diving? Lol weird but help!!!?

When i go to cancun mexico im going scuba diving. Im worried because of the sharks (if there are any) and the gas tank thingy. Im worried if it will run out of Oxygen or something and I Will die!!!!!! have you ever used one? Im only 13!!

First off let me say you are a very lucky person cancun has some amazing diving. sharks are no big deal i have been certified as a diver since i was 14 and in my 5 years of diving have never had a problem with them they are sweet to see. As for you tank they hold over 3000 psi of air and you have a computer with you that u can hold in your hand that tells you your air left, also you will have many ppl with you that can help if anythign should happen. if your air runs low just surface. good luck and happy diving
