Technical Diver

Technical Diver course gives the students an opportunity to reach targets outside of the scope of traditional recreational diving.

In Technical Diving you will be able to use the skills learnt from Extended Basic Skills in real scenarios. You will also be able to make more complex diving and you will learn how to handle accelerated decompression using up to 100% oxygen. The Technical Diver course will also allow you to use trimix which is beneficial to reduce narcosis and a more easy to breath at depth. The introduction of standard gases will allow you to plan the dive efficiently and safely and will also reduce confusion when diving with a big team.

 

After passing the course, the student is able to:

  • Configure and use equipment for technical diving according to SwedTech Diving equipment configuration
  • Plan and conduct dives that require Trimix, Nitrox or Oxygen for accelerated decompression
  • Plan and conduct dives that require normoxic helium-based bottom mixes for lower equivalent narcotic depth
  • Understand and plan overhead dives, both in physical overhead environment and with decompression stops which create artificial ceilings
  • Solve multiple equipment problems which can occur when diving with technical diving equipment
  • Solve problems during diving using backup plans
  • Solve a problem of gas loss and prevent a serious gas loss
  • Simultaneously use several different swimming techniques to manoeuvre forward, backward and during turns
  • Show excellent buoyancy control, both during the bottom phase of the dives and during the ascent
  • Understand and use the advantages of diving in a well-balanced team
  • The use of more than two stage cylinders

Course outlines

  • The student should have at least 12 hours of dive training in the water
  • The course can be taught in ocean, sea or sea like environment
  • At least two of the dives should be to a depth of between 45-60 meters
  • The student should have at least 10 hours of theory and briefings

Limits

  • Maximum PO2 for bottom gases is 1.4 bar
  • Maximum PO2 for decompression gases are 1.6 bar
  • Maximum Equivalent Narcotic Depth (END) during the course is 30 meters
  • Maximum depth during the course is 60 meters
  • Maximum three students per instructor during the practical training in the water

Prerequisites

  • The student must be at least 18 years old
  • The student must be in excellent health
  • Have passed the Extended Basic Skills course
  • Have a proof of at least 100 dives in various environments, at least 20 of them should be to around 30 meters
  • Have made at least 50 dives with the equipment used on the course (excl. the deco cylinder)
  • Use several different swimming techniques to manoeuvre forward, backward and during turns
  • Show excellent buoyancy control, both during the bottom phase of the dives and during the ascents. Be able to hold a stop for at least 20 minutes without deviating with more than one meter from the target depth
