I'm roughly 5'5"/5'6" depending if you ask my wife or me. An Al 80 is a bit tall on me but nothing that isn't crazy annoying. Now if you're 5'3" and below then yes it's a pain in the ass especially if you're gearing up on a sit-down bench. Aside from that it's not a problem for me when I'm...

Normal wear and tear using muscles and high mental taskload that you're not used to. It comes and goes as you take more classes too; which is both humbling and unnerving. Drink some tall glasses of water as your body isn't used to dehydrating from dry scuba air. A protein bar or shake can help...

It only takes approximately 4 ft (ie. little under 4ft or over 4ft) for you to embolize and kill yourself should you take a breath at depth, hold it, & ascend. That's one risk on your physiology. For more risks you will face, more info is needed.

Your terminology is off which is part of the reason for our confusion. A traditional Diving Kit consists of the following: Exposure protection (Wetsuit, booties, gloves, hood) Mask (not goggles) Fins (not flippers) Snorkel BC (Buoyancy Compensator) Regulator (Consists Primary mouthpiece...

The SR1 Octo is the exact same as the SR1 Primary. You just change out the color of the purge and tune it to be slightly more harder to crack than a Primary. Having said that your SR1 second stage is the highest Sherwood has to offer, the Magnum is about a half step above the Brut which is...

IMHO Tonybee & Lowrey are baby steps towards Frenzel. You'll find that the downside to the first 2 require actually swallowing. Trying it right now, even with a very wet mouth, you'll be hardpresses to do 2 rapid swallows in a row. Your muscles aren't conditioned for that rapidness, nor do I...

Here ya go: Equalization question I wrote a little synopsis of the 3 main methods divers/freedivers use to equalize. It is much easier to look up an actual dedicated blog tutorial on the 2 advanced methods, VS retyping it all out here. The main 2 others you're probably looking for at Frenzel &...

Yup, longer primary hose on an Angle Adapter or Swivel. You should aim for 40-44in; that will keep it tucked under your arm without being super long but also giving you enough room to turn your head. Don't forget to practice dumping air while breathing off the Safe Second. That is equally...

I use FFM's with communications for work. Love it in practical use but in theory I can be not a huge fan. The good: It fixes all your problems with on the fly decisions that may come up on a dive, even with the most detail orientated planning & backup planning. You can now sort everything out...

Genetic mutations during development can create 4 legs when there should be 5 normally. Same way some humans can be born with an extra digit or lack the usual 10 & 10. It's not usually environmental conditions but just DNA errors that manifest into a physical trait. A typo when the parental...

Well assuming you Analyze then label the tank properly: If you partial pressure blend: Fill with O2 then top off with Air, the Analyze you get right after fill will be off from what you analyze hours later. The air has to mix before it is uniform. It's not a very big change, but it is a change...

Scubaboard: "Get a Bp/W! It's simple and minimal. You don't need all those bells and whistles #@%#$$!#" "Stock BC's with all the bells and whistles are terrible! #%#$$#@%$" "Equipment Solution to a skill problem! @$#%#$#@$" "You should learn to be skillfull and practice your scuba skill...

Do you open your throat like a yawn when you do the Valsalva? Common mistake is to constrict your throat and tongue block the back; basically mimicking like you're blowing your nose. This blocks your Eustachian tubes and in some cases your throat and/or tonsils completely shunts the opening...

I typed that wrong, but the way it's usually said implies it. "Pinch your nose and blow" is the common saying now days. In my opinion, that doesn't imply that you should be keeping your throat expanded or relaxed. Most natural land-lubber action that's similar to this is to blow your nose (You...

On your first dive, try equalizing slightly differently. Pinch your nose and blow your throat. As in open your throat and blow as if you're doing a yawn. Biggest common mistake in my mind for our industry is to tell students to pinch and blow their nose to equalize. Your Eustachian tubes are...

I have to pee-I have to pee; get in the water, get in the water now!!!!!! Sorry, what were you saying about patience? It kinds comes and goes depending on the flow. :D But to reflect on what TMHeimer said, teaching classes. I've gained a lot more patience during the setup/gear up process.

No experience with it, but I just went ahead and looking online for the manual. English Manual for Mares Matrix Pg 13-14 The paraphrase shows arrows point up or down or level. Going over the obvious IT questions, did you read your manual Cover to Cover? Do you understand the interface & all...

Woohoo!!!! You'll be waving to little kiddos on the other side of the acrylic in no time!

An equally fun group. I don't have any inside jokes with those folks yet, sadly.

Bahaha. I was hoping to satisfy my curiosity if it was NY or NJ Adventure Aquarium. Good luck anyways! If it's the NY DSO named Roger, tell him an ADSO who likes fountain pens said hi. =P
