Technical Diving Cross Over Course

Want to move into Technical Diving but don't know where to start?

Technical Diving starts a whole new level of equipment, preparation, and skills that the standard recreation classes don't even come close to preparing you for.  Many students are considering starting their technical training but don't know where to begin.

Let HiTek Scuba get you started off on the right foot.  We've specifically developed this course for you...the recreational diver with lots of single tank, cold water, PNW diving experience, but have never taken a "Technical" training class.  THIS IS WHERE YOU START!!

 

If you've been around a while you've probably met the  pre-requisites by now, but just in case they are:

  • Deep Diver Specialty
  • Enriched Air Nitrox
  • Minimum of 50 Cold Water Dives
  • Own your own gear
  • You must be able to swim 100 yards in full gear
  • Good physical fitness (able to lift heavy gear)
  • A good attitude with a willingness to change the way you think about diving
  • A safety oriented attitude towards diving
  • A completed RSTC Medical form signed by your doctor within the last year.

 

This course is absolutely not for everyone.  Deciding to move in the direction of technical diving needs to be a well thought out decision.  It is definitely an increase in risk, and while we work hard to do a good job managing risks, technical diving is absolutely riskier than recreational diving.  Even if you do everything right, there is still a higher inherent possibility for an accident to occur leading to permanent injury or death.

It's possible that you're thinking hard about it but you need some questions answered first like:

  • What is the difference between Recreational and Technical Diving?
  • What makes Technical Diving greater risk than Recreational Diving?
  • What are the benefits of technical diving?
  • What are the disadvantages?
  • How much is this "new" thing going to cost me?
  • What kind of new equipment will I need? Why?
  • How much training will I need to start doing it?
  • Are my skills good enough now to start? How do I know?
  • What is different about emergency procedures between Technical and Recreational Diving?

HiTek staff will evaluate your skills

  • You MUST be able to maintain your position in the water column while doing other tasks.
  • You need to be comfortable underwater with or without out a mask.
  • You need to be able to swim close to the bottom without touching it.
  • You should be VERY comfortable manipulating multiple pieces of gear.
  • You MUST be able to stop your ascent in mid-water and stay at a given depth without difficulty.
  • You also need to have very solid self-rescue skills.  Situational thinking underwater is critical.

Topics include:

How do you find your Surface Air Consumption Rate?
What are your gas supply requirements for a given depth and time?  How do you find it?
How do you determine how much actual gas a given cylinder contains?
CNS review; What is it? What are signs/symptoms? What method do you use to manage it?

 Basic Techniques and Procedures

What general elements does a technical diving pre-dive check cover?
