and told you I would do my best to research before asking questions.
Some basic research is nice of course, but sometimes asking questions is the better way to go. You don't know what you don't know.
This is the retelling of what I have experienced.
I created a similar post for learning Sidemounting.
I thought this might be a fun thread, where I share observations, lessons, and situations I'm facing as a newbie sidemount diver. It's likely I'll embarrass myself and invite plenty of critique by creating this thread (be nice), but it's better to take & share learning opportunities than hide...

I managed to get a Snorkel Pro mask
I'm not familiar with that mask. Is it a snorkeling mask or a Scuba mask? Regardless, the most important thing is having a good seal. Put the mask against your face, breathe in and see if (or how long) it sticks.
trials and tribulations of a 50+ year old out of shape guy learning to dive
You only have one life. Might as well live it. I probably procrastinated 5 years on getting my scuba-cert, from the time I seriously wanted one.
, and a SMB (Surface Marker Buoy) in order to take the class.
This seems a little odd. I'm not entirely against every diver having an SMB, but in my open-water class, we weren't required to have or use one.
Every one felt great, and I realized that while I had a mask, it likely hadn't been properly cared for and might need replaced.
You're lucky, most scuba-masks do not fit my face well.
Yes, I found myself constantly thinking about this or that, which didn't allow me to "see" all the "stuff" around me. I had tunnel vision and my situational awareness was terrible. Oh crap! I just blasted the bottom with my fins and stirred up a bunch of silt. Do better!
This is normal for several reasons. It's a combination of being "task loaded" in an "alien environment", covered in lots of unfamiliar gear, and actual literal tunnel vision caused by refraction.
TIP: I could have rented two wet suits to avoid putting on a cold one. I'll remember that next time.
You can actually layer up wetsuits if they're the right size as well. It will restrict your movement, but if (for example) you have a 2mm and a 5mm, you might be able to wear them both to get an equivelant of a 7mm wetsuit.
Upon descent, I learned that it was 5'~7'. Oddly, that wasn't uncomforting to me.
I dive in absolute zero vis sometimes. So long as I can feel the bottom, I'm usually fine (also so long as I'm pulling up fun-loot like sunglasses).
Remember, I had hoped to be able to get all the way through Advanced Open Water during this trip.
AOW might be a little challenging to go straight to form OW
I already have some questions that I will throw out. I'll keep them confined to this thread again with the goal of helping others. Thanks for reading.
It's fine to create another thread if you have a specific topic, that may result in a long-form discussion. I can't imagine many people will read past the wall-of-text. Not a criticism, just a reality of attention spans and how much time people have.
DISCLAIMER: Again, I am here sharing my lived experience(s) and yours might be different and that's okay.
You already said you were new in the beginning of the thread. This isn't facebook or twitter, hah, people here are fairly chill.
Why is it so important to continue to "blow bubbles" whenever you don't have a regulator in your mouth? Why must you always breath? Why can't I hold my breath?
You don't have toe exhale every last bit of breath, but rather you want to keep an open airway and allow air to escape. One of hte big-dangers is you may not be managing your bouyancy as well as you like in an emergency. Remember how you got tunnel-vision? If you have some kind of incident/accident underwater, it's likely you'll experience the same thing, and may accidentally hold your breath while ascending because you haven't built up good habits.
Also, in an emergency ascent, if you're going up, it's almost like having more air, because the air expands.
Skip-breathing, where you temporarily hold your breath, also tends to cause you to use more air overall. You'll start to get a CO2 hit, which then forces you to breathe faster, and it can take a while for your breathing rate to come down.
Now, if you're worried about the idea of ever being OOA, and your buddy isn't there to rescue you, you might consider looking into having a "pony" bottle or redundant air source. More info here:
