“ The program includes four open water dives, which are conducted over at least two days. The minimum depth for the deep dives is between 18 to 30 metres/60 to 100 feet, with no dive exceeding 40 metres/130 feet. All your dives will be conducted within the no-decompression limits, with deeper dives conducted first. „

This is a four dive minimum 2 day course that gives you a speciality.
specialities can be used to count towards other qualifications for example the master diver or just to expand your skills and knowledge.
The deep diver gives you more practice at depth which is a very important skill as if something were to gowrong you would need to calmness and knowledge to know what to do as it isnt as simple as just getting out when your at 30m or something similar.
The four dives have different skills which are all basic enough but give you good practice and help your instructor see how you deal with the situation. The dives build up to your last one which is a 40m dive, by building up you have a gentle increase in depth instead of just throwing you in at the deep end literally!
On the 40m a task such as inflating as empty water bottle by breathing into it and doing it up when at the bottom then opening it on the surface to demonstrate the pressure difference may be done.
The course is one more for people that want the experience than those thinking they will from then on be diving at 40m every day because in reality few centres will do dives that deep except for during the course so although it gives you valuable experience and is good to see how you react is if the narks hit you (this is not the benz its where you basically feel drunk for nitrogen build up in your system and is relieved by going shallower and leaves no permenant damage, but is unsafe underwater because some dont act safely and rationally which is why narked divers are taken up) to know if you do get narked is good to know and also if you do it helps to know how it feels so yoou can react yourself to early signs. The reason it is good to know this is because, for some reason one day you may over exceed your depth, or you may get narked at a shallower depth, it is not set but varies depending on your physical and mental state each day.
so in summary the deep diver is great for experience but wont neccesarily open up a whole realm of new dives for you.
Try it if you want but please dont until yoou are competant in the water, you must be 100% happy you knwo your gear, and your self. I have assisted on deep courses where people couldnt get s good swimming posture and therefore could not decend quickly meaning the times down there were limited more than usual and also one diver who did not check his air once until he hit 30bar whilst at 40m! this was not good all worked out fine but could of been serious. It was immediate ascend time with my alternate air source waiting.
Although it is great when anyone wants to do these courses dont try the harder ones until your ready.
And please check your air a lot when deep you will be surprised how quickly it goes.
Also descents are usually quick to get the most time at depth before your ascend times and also to get as much air as possible and if in a current if yoou take too long you will miss your point. So if you are not comfortable with fast descents possible in the blue again dont do it until youve had more experience.
After completing the PADI Advanced Open Water course I decided to take the deep diver element a step further, and complete the PADI Deep Diver Specialty course. The completion of this course qualifies you to dive to 40 metres, which is the deepest recreational limit for PADI divers.
In this review I will cover the course as well as the book, as anyone buying the book will be completing the course as well.
The manual follows the same format as all specialty books, which is great because if you do a number of these courses these books will always be familiar to you and are very intuitive and easy to use. It begins by telling you what the benefits of doing this course will be, which you may not really be interested in reading but this is the PADI manual standard.
It goes on to cover a number of sections that you will then be tested on in your knowledge reviews, so make sure you pay close attention and do the activities as you go along as this will help you when completing your reviews. Over ease of completion, it should be understood that this is all aimed at ensuring the diver's safety - an emergency at dept can be extremely dangerous and so nearly everything included in these sections is safety related.
You will need to complete 4 dives on this specialty course, you may be able to just complete 3 as you will have done one as part of your AOW - this however depends on the dive school and their policy.
The dives cover a range of activities, but unlike many other courses these are not skills based so much as they are awareness based. When doing deep dives it is of utmost importance that you are able to recognise the signs of diving problems such as nitrogen narcosis and decompression illness, and know what to do in these situations.
The activities are fun, and you will find yourself being tested on various tasks at depth which will frustratingly elude you. I had to complete a number of maths sums at 24 metres, and was over a minute slower than my times on land. A friend of mine was asked to identify the colour of a card at depth, and had forgotten the instructions so ended up writing her name!
All in all these dives are fun, but the underlying message will not escape you - if something goes wrong at these depths you need to be prepared, it is dangerous.
Many divers decide that just because they can now dive to a certain depth that they should - this is not sensible, nor is it even logical. The deeper you dive the quicker you use up your air, at 30 metres you may use so much air up in 10 minutes that you will need to begin your ascent - this isn't fun and you probably won't have seen anything interesting in that amount of time. If your aim is longer deeper no decompression times then do the enriched air diver course, this will give you some extra time, and is particularly useful when doing wreck dives.
On regular dives however, just go where the action is. My deepest dive to date is 34 metres, and I have been qualified to go to 40 for a year now. The most exciting thing I have encountered on a dive is a 3 metre White Tip Oceanic Shark at 2 metres!! You never know where the best encounters will be, just play it by ear and don't dive off your profile.
