First Skills of Tec Dive

32 28

Technical diving (also referred to as tec diving or tech diving) is scuba diving that exceeds the agency-specified limits of recreational diving for non-professional purposes. Technical diving may expose the diver to hazards beyond those normally associated with recreational diving, and to greater risk of serious injury or death. The risk may be reduced by appropriate skills, knowledge and experience, and by using suitable equipment and procedures. The skills may be developed through appropriate specialised training and experience. The equipment often involves breathing gases other than air or standard nitrox mixtures, and multiple gas sources.

The term technical diving has been credited to Michael Menduno, who was editor of the (now defunct) diving magazine aquaCorps Journal. The concept and term, technical diving, are both relatively recent advents, although divers have been engaging in what is now commonly referred to as technical diving for decades.

    It's really refreshing to see such precise scuba skills. It encourages me to want to work towards the same goal. Somethings all divers should consider.

  2. Gary H says

    There is no such thing as perfection, but that's about as close as you can get! Well done!

  3. ezzedien rabie says

    Excellent video, awful music. Please repost it with another music track

  4. Wojciech Chróśćiel says

    While sharing air you should always hold on to each other.

  5. Ms Tek says

  6. bristol says

  7. Wally Brown says

    The dude is goood.

  8. TecDive says

    this doesn't look like tech diving to me – it looks like regular DIR skills that gue and utd have been using and teaching for decades …

  10. Bram Peeters says

    WoW crazy techniques!

  11. JCA ELITE SCUBA says

    Your back kick was very good but I do a little less calf movement on the modified flutter…. just move the fins. Yes yes yes on the reg recovery! I teach this to my open water students! Put your alternate in first. Breathing first then you can take all the time you need to find your primary. I include bubble check in the s-drill and have the diver complete the turn if exiting single file.

  12. dean moore says

    good basic drills as advertised..however….Trimmed tech..why no H valves?

  13. Jason Smith says

    Music please?

  14. diver dave says

    WOW… 40 years ago I took the YMCA scuba diving class… Our instructor made sure we could do everything except for your advance trim moves…. SAD to say – these days its way to easy to get certified ! Are you using US Diver Rocket fins ? Mine are 41 years old and I still use them a lot and LOVE them

  15. John M says

    NICE!!! Good demo…. great trax. 🙂

  16. Nolan Olivier says

    Great video; especially useful for those, like me, who are novices but have definite ambitions to become technical divers. One question: which agency is the best place to turn to for instruction in technical diving?

  17. ChefderArmy says

    Reg Replace and mask blow out are basic skills.

  18. John Clarke says

    Most of those skills are taught in basic CMAS training. Nothing special here!

  19. Steve DeMayo says
