What To Expect On Your Discover Scuba Diving Experience
If you are doing a PADI Discover Experience, which is the most popular program of its type, they will start you off with some paper work and introduce you to your instructor. Other certification agencies like SSI have similar programs that follow similar but different procedures; all have the same goal in mind, to make you feel safe and confident in the water, and for you to have a great time!

The instructor will more than likely have you look at a Discover flip chart. This flip chart will have some important dive theory and some important dive rules and things that are important for you to remember, such as the golden rule of of never holding your breath and equalizing your ears and air spaces every few meters or when discomfort is felt. The flip chart has lots of great graphics on it that explains the theory very simply, easy enough for even kids to understand quite rapidly.
The instructor will then do a pre dive brief explaining the procedures, signals and the skills that you are going to do in the water, which include skills for recovering and replacing your regulator, clearing your mask of water, finding and using an alternate air source. There are some other simple skills as well that you will be asked to do. The instructor will help you into your equipment, and make sure that dive gear is set up correctly
The instructor will then take your group into shallow water, in a pool, or pool like conditions, which you can stand up in at anytime. The instructor will explain the skill that you are going to do, and then you will go under water together. The instructor will demonstrate the skill first, then ask each individually in turn to do the skill. The dive instructor may ask you to repeat a skill if you miss an important part of it, or if they feel that you didn’t get it quite right. After everyone has done the skill to the instructors satisfaction, you will all go to the surface. The instructor will talk again a little bit about why the skill is important, and point out some tips and pointers, so that you perform the skill a little better. He or she will then explain the next skill and you will repeat, the instructor will demonstrate, the students will do, and when everyone is doing the skill satisfactory, they will all go to the surface

Gauging DOT 3AL3000 SCUBA cylinder neck threadsIn response to requests for clarification, from members in the Far East and Australasia, the following guidance is issued for SCUBA cylinders and valves that utilise the ¾" NPSM thread form.
ASSET recommends that technicians, involved in the assembly and maintenance of SCUBA cylinders and their valves, use the appropriate, calibrated, thread gauges as a means to ensure that they are both within tolerances and compatible with each other. Additionally, the technician should have received training in their use, as provided in the ASSET Dive Industry Technician’s and Cylinder Tester’s Courses and Manuals.
How to Avoid Isobaric Counter diffusion hits during trimix decompressionIsobaric Counter Diffusion triggered by breathing gas changes is predominantly a problem when carrying out Trimix dives that are deep enough and long enough to generate formal decompression stops that require the use of a hypoxic Trimix. An analysis program embodying these concepts to identify known unsafe ICD gas switching practices and unsafe decompression is made available
and discuss it again. Normally this takes somewhere around 30 minutes, depending on the group.
The instructor will then in most cases take the group from the teaching area, out to an area where they can take you for an underwater tour, introducing you to a whole new universe. For most this will be a dream come true and a life changing experience, and certainly one that you will remember for a long time to come. Many do the Discover to see if is for them, if it is, your PADI instructor or Dive Center will encourage you to do the whole PADI Open Water Course, many dive schools and instructors will discount the Discover Experience from the course price, as they know if you are interested before, you will really be turned on after you have taken your first breaths underwater in a new world. Have fun and we’ll see you underwater soon!

Deriving the underlying laws and predictive mathematics for diving physiology, safe decompression, Oxygen toxicity tolerance, narcosis, and HPNS (High Pressure Nervous Syndrome) have challenged the minds of the worlds brightest scientists. That many of the victims of incorrect decompression fail to survive extreme decompression and be part of the observable phenomenon database further hampers progress. As a first topic in this series of articles we will take a more in depth look at decompression and how to survice it's more extreme effects.
