    Current opinions on Padi Tec-rec?

    Bringing this thread back around to what the OP was about... Another good way to select your Tec Instructor is to ask for prior-student referrals. I ask my students if they are OK with me passing along their email to future students who are considering taking me on as their TDI Instructor, and...

    Current opinions on Padi Tec-rec?

    A few comments vis-a-vis the above: If you're trying to reach out to a potential Tec Instructor you are thinking of hiring and they are unresponsive, that should be a red flag. Agree with whomever said, 'just because you have a Helium card, doesn't mean you have to dive Trimix.' More education...

    What are the accessories that you will always dive with, and why ?

    DSMB and reel. I’m a tech instructor and I will never get in the water without these two... even for a 30’ reef dive. I have two separate stories of friends, better divers than me by far, whose lives were saved by their DSMB...

    Hydro Atlantic without Helium?

    The important thing here is to know yourself and know the conditions. Are you susceptible to narcossis? What's your personal limit? What's your experience been diving similar conditions (temp, current, viz) at shallower depths? If you really should be diving Helium mixes but the cost is...

    Advice to get lower SAC?

    Rhythmic diaphragm breathing may also help you lower your SAC rate. It's also healthier as it cycles more CO2 out of your lungs with each breath cycle. Focus on drawing gas into your lungs using your diaphragm muscles as opposed to your neck or chest muscles. Then exhaling using your chest...

    Would YOU thumb this dive?

    As a general rule of "thumb," you should thumb a dive the minute you ask yourself if you think you should thumb the dive. There is always another dive... if you follow this rule.

    Apeks Tec 3 country of origin

    Apeks manufacture their regs as stated above, in Blackburn, Lancashire, but what is also of note is that they machine most of their components themselves as well, or at high quality factories in Germany.
