Oxygen toxicity occurs when the lungs take in a higher than normal O 2 partial pressure, which can occur in deep scuba diving. (Photo credit: Wikipedia)Good Advice Dave Albright::::
There are so many dive shops offering abbreviated Scuba Courses. Don't Do IT. Think about it for just a second.... Does it make sense to try to cram a little knowledge in a short time just so you can get certified to take part in a potentially dangerous sport? The cost is almost the same for a full length course and look at what you get. The attention of a qualified Scuba Instructor for days instead of a few hours. Time in the pool to practice what you are taught and to become proficient in the skills.
This is going to sound funny but time to forget how to do the skill and then reacquire the skill knowledge. Anyone, including a monkey can mimic a skill a few minutes after it is taught. If you have some time in between learning and demonstrating, you will find you actually retain it better.
You will not only have a book to read and take quizzes, you will also have a CD to review the material and most importantly you can ask the instructor questions about anything that is fuzzy. Also, others will ask questions that only make your learning better.
Also, ask yourself 'do you really feel qualified to dive in the ocean with kelp, waves, surf & critters if you only do lake dives in a local lake to become certified? I have heard of divers who become so-called advanced divers who never have been diving anywhere but a local lake. That is not an advanced diver and you have been done a disservice being called one. It does a couple of things
1. Gives you a false confidence.
2. Gives others a false sense of your skills
3. Puts you in danger because you can be exposed to diving above your skill levels.
I have been teaching Scuba Classes since 1984 and they have never been quickie courses but rather the 4 week variety (twice a week sessions) with a full complement of dives at the ocean. The divers I have taught are regularly recognized by dive masters both in Northern & Southern California Dive Boats as superior divers, having skills higher that the 'Advanced Divers' that have only had quickie courses. Also, dive masters at resorts in warm diving areas have often commented on the skill level of my former students. This is not because I am some wonderful instructor, but because the students assemble and dis-assemble gear several times, practice skills until they become second nature and have time to make mistakes and get them corrected in the pool before becoming certified!
It takes time and some effort to become proficient in Scuba. It is not safe to jump in 'over your head' to try and do skills you haven't been properly trained for. Remember, you are only qualified to dive in areas and skill levels similar to your training.
Don't put yourself in life-threatening situations by not being properly trained - take only full length and featured Scuba Classes.
