    The only marketing for an elite diver certification I was able to find in our recreational pass time is this: PADI Seal Team | PADI What sort of goals or experiences are you hoping for in your new hobby? Cameron

    Unusual encounters?

    Starting a thread where we can keep track of and marvel at the unusual/unexpected experiences. Today I spent a few minutes with a hammerhead shark. The first I've seen here! Somewhere near Santa Rosa wall. Was cruising at ~150 and saw it come up the wall towards me from beyond the range of...

    A DPV, kind of

    I was told for 15,000€ you can get the "rescue" model. ... If your team is "worth it". And compared to a fire truck or rescue boat the price is low. Specs: Suppose compared to luxury cruiser in the promo video it is fairly cheap as well. Cameron

    what happened to Nagel ?

    Here's what I was able to find: It appears he was active here 2006 - 2017. Similarly on the scubatoys forum he stopped posting in 2017. Trip advisor as well his last post was early 2017. His dive blog also was last updated in 2017. I don't know him personally to answer your question. He has...

    Kit rental Riviera Maya?

    Playa del Carmen you can easily get rental kit from dozens of shops, some will rent instructor discounted seats on the boat as well. My favorite for a more peaceful setting would be: Just north of tulum, Casa cenote is a nice place for OW dive training with shop across the dirt road who will...

    How do I calculate my consumption rate?

    6 cf ÷ 17 minutes = resting surface air consumption rate The issue with this becoming useful is while bills are stressful they are likely less of a workout than actual diving. To convert this number to something helpful for dive planning you'd apply a theoretical multiplication factor to guess...

    Lionfish Eradication: Recipes, Killing Techniques, and Information

    Uploading an ugly shot for critique of how to strike with less damage to the reef. How would you have done it differently? Here's a more peaceful clip of reef destruction I witnessed a couple years back: Cameron

    Trimix blending without O2

    Poor man's mix. Still used in remote locations. www.advanceddivermagazine.com/ADMEZINE/HeliairPoorMansMix.pdf Logistics side of things: It's simple to go from cga580 to 1/4 to a hp hose on a first stage. I set myself up for ~14$ to transfill helium (plus the helium bottle). Heliair??? Old...

    $5, 5 minute bcd flush hose build.

    Nice solution to rinsing, looks solid. I particularly like projects that involve finding uses for old parts. Cameron With great power comes great responsibility. :D

    Building on OW cert

    Here's a little different angle. Dive dive dive. You could go a lifetime without another moment with an instructor and be perfectly happy enjoying your new hobby safely. There's tons to experience within the scope of what you've already been trained to do. If you find something that you want...

    Regulator test rig you don't need to suck.

    Do these components look right? Without the satisfaction of wiring up a custom pwm of course. Cameron

    What's your favorite set of doubles?

    When my back could handle it lp131s with a cave fill were convenient. Now it's always a tradeoff between how sore I want to be the next day, availability and what's the least gas I can carry to do the dive.

    Nitrogen Narcosis - Deep air dives

    At the risk of being redundant, until you have the contrast of a few breaths of trimix (easy to do) or problem solving under duress you'll be unable to self diagnose in a meaningful way. I'll try to explain my concern another way as someone who regularly still dives deep air: I'll comfortably...

    Practice Dive Plan tables ?

    As you may be noticing, asking for dive planning practice help without specifying which tables you are specifically interested in will result in a broader perspective on dive planning and you may accidentally learn something beyond the limited scope of a padi DM program and their proprietary RDP...

    Nitrogen Narcosis - Deep air dives

    Glad you're enjoying your dives. As mentioned up thread, doing math calmly underwater does little to nothing to indicate narcosis levels or demonstrate what could well be a deadly level of impairment in case of a stressful situation. You're discovering this for yourself now but it sounds like...

    Trim Weights

    Ouch that looks uncomfortable! Trim weights or floaty pants would help. Are your fins/legs/booties unfortunately negative? Or are you certain it's torso?
