I'm usually one of the last to run through a tank and I would not want one. I would not encourage people to dive using equipment that encourages inattention.

Thanks ❤❤❤

The scott air packs in the 1980s would have a little like sound when you had low air..

Scubapro right?

It sounds a litte bit like the old telephone, when they ring. So it’s like, your tank is calling you. :)

Great to see the vintage scuba. 👍 Have a great Christmas Alec & Happy New year.

Mine whines a little once I drop below 700 I think mfgs should incorporate that

300psi! You’d better not still be very deep when that started buzzing!

How did Low Pressure Warning work on a J-Valve?

Cheers Alec.

I very much hope that you get a chance to come back and visit us crazy South Africans again, in the near future! :) Also, we have biltong. Thanks for the informative video. - Craig

Hi Alec I wonder if there would be a different result if the aluminum tank was made of that 6351 material that those recalled tanks were made of? If you have seen those videos of the valves being knocked off a large industrial gas bottle, they take off like a torpedo, a lot of stored energy inside them, It might have been better to shoot the shark. Take care Owen m

I thought I may have punctured my brand new hollis bcd today. (I didn't). But it got me wondering if you can repair them or not. As soon as you said lifetime warrenty I felt alot better

Very curious to know: what are your thoughts on the "right to repair" movement, as it applies to diving? I ask because my situation is one of a land-locked diver with access to VERY few shops whose repair service is... questionable... at best. I was going to surprise my wife with a pink purge cover and when I took the cover off found that the "serviced" reg was sent back to me with a broken inner cover and missing a friction washer. That made me uncomfortable to say the least. I turned to wolfinger and harlow and great online communities, spent the money on gear, and started double checking everything to find intermediate pressures to be off on two out of five regs (my whole family dives), and missing an o ring on another. I trusted the shop owner... Great guy, skilled instructor, but wasn't mechanically inclined, nor business savvy. He ran the shop because his training agency affiliation mandated he be associated with a shop to instruct, and since there were no others in our area, opened it himself... But his heart and skill are only in diving and instruction, not the shore side stuff. Since then, i switched to some of the "repair friendly" tech brands rather than the high end chromy ones that won't sell parts kits to US (not sure about Canadian) consumers (though they sell direct in the rest of the world). I understand both sides of the coin--on the one hand, I'm NOT a reg tech. I don't have experience across multiple models and brands nor years of exposure to failure modes. I can pretty much service my reg, and that's it. There's still a strong safety argument against my actions, as well as a profit/warranty/liability one. On the other hand, I'm doing probably the only thing that most divers require, and there's no law regarding manufacturer liability and state-certified techs... It's an industry system, which failed me in my specific case, and I'm probably not alone. I think my position would be to allow supply of parts to anybody, on the condition that you can't install them for anyone else/the manufacturer is indemnified for warranty and liability purposes unless installed by a certified tech. The rest of the world seems to get by with direct sales. Would love to hear your thoughts, though (as well as on some agencies' mandates for shop affiliations for instructors, which was a proximate cause of my issues).

My favorite is when I return half of the regulators they serviced for me and tell them the intermediate pressure is out of range. The “oh shoot” look on their face when they find out I checked on their work. (Truth is, I had it on my bench because I was servicing our OTS guardians and had the regs sent out because scubapro wont train us for servicing.)

Hi Alec, a great clip again, but a great idea as April's fool to tell: I disassembled my reg set, would you mid to service them. 😁

Hi Alec, love your videos, I have a question about leak testing or water testing regs post service, I connect my first stage to a pony, pressurise and dunk it into my fill station water bath, is this how you do it or is there a better way. Cheers, Pete

I decided it's too dul at Catalina. I'm going to get one of these, hide in the kelp, and ram unsuspecting divers.

best disassembly tools are vise grip, heavy hammer and a good cold chisel !!! In fact, most poeple will do more damage than they can help the process so better to leave everything intact and bring it to a competent regulator technician. a meticulous , mechanically oriented person can safely do the revision procedure but he must work very clean, have the workshop of his regualtor and have an access to minimal specialized tooling. very good point

Seems like from your explanation that new divers would benefit more from the buoyancy characteristics of steel since they often struggle with buoyancy control. So going from a negative to positive buoyancy as they breathe down their tank would make it worse

In my experience - if you tell LDS that you need the reg in 2 months , it will be done in 2 months. 😂

Interesting and good to know...

Hey Alec Peirce, can you do a video about the first two stage regulators and how they were perceived in the dive community when they first came out? It was way before I was born but I am very curious on how the people that were diving back then felt about the new technology they brought in to regulators and did the die hard old time divers that had used single stage regulators take to them or were they shunned as unnecessary and made things seem more complicated at the time or fid the divers say wow these things are great!! ? Thanks Bill

Don't forget to tell them you have a 1979 decor 360 first stage and a pacer, 2nd stage, that's been hanging on the wall of your barn for 26 years and you forgot to clean it the last time you used it.. lol. Fortunately mine still looks like the day it came off the dive Store shelf... I might build ma a glass case and put it up as a display. Lol.

👍🤿😎!

Love your videos 🙂

What about removing your AI transmitter and reinstalling a port plug? Good or bad idea?

Great video. I have a leak around the shoulder dump valve - where the material meets the actual dump vale. Can this be repaired or do I need a new BCD?

4 months and counting waiting on a dive shop to fix my reg....that i bought 7 months ago.

when you mention a product it would be nice if you mention where yucca purchase it or have a link for it. googled it & get life insurance from BC, Thx in advance.

Nothing better than getting the notification that Alec has a new video.

Just watched all 155 Sea Hunt videos in order on u tube.

And Cole had to make sure that he actually can do a repair on your regulator. Some shops only work on certain brands because they need to be certified to do it.and IF you happen to own a old Dacor brand regulator - my good friend Alec used up the last known repair kit on mine and no one will be able to fix it up for you !

I had that book, unfortunately gave to my nephews & it got destroyed.

Merry Christmas Alec to you, Kevin, and your families. Thanks for a great 2024 with some great KZbins. Looking forward to 2025

A Customer dropped off a regulator for a "Honking" sound when I did my Nitrox Class(At the shop)

I'm Nitrox Certified. Getting my tank cleaned and annual inspection next March

If memory services me Stan Waterman was diving in his 90's. Unfortunately, he passed away last year at the age of 100.

I have the MR 12 II. I stopped using it in the early 1980's. I didn't like the air being shoved down my throat. I felt like I had to be using more air because of it. I like the hose routing of the first stage. And it is one of the smallest first stages out there. I haven't been able to get parts for it. But, recently I found a Mares dealer that says they have the parts and can service it. I love the Aqualung Conshelf. But, I like the hose routing better on the MR 12 II.

Nice DSMB. One thing I don't like about DSMB's is they usually don't fully inflate by the time they reach the surface. So they are just lying flat not vertical. Do they more fully inflate using the inflation hose? Someone should come up with an easier to deploy DSMB. Especially needed for new divers.

Little history for people. I'm sure Alex is aware of all this. I believe the only changes to the Aqualung Conshelf first stage since the XIV has been the number of ports or the size of the ports. I am only refering to the first stage. I have a Conshelf XIV with the cold water kit. Which essentially makes it what Aqualung called the Conshelf Supreme. We didn't use the silicone liquid in ours and the regulators worked fine. I have a couple of Conshelf 21's and the only differences from the Conshelf XIV are an additional LP port and the HP port is 7/16". Last time I checked Aqualung was still selling the Conshelf 14 to the US Navy. Interesting story about XIV vs14. Which includes the old Chrome second stage from the 1970's. The Navy standardized on the Conshelf, I believe in the 1970's and still use it today. If any are interested there are UT videos of the US Navy SCUBA class and you will see them using the Conshelf regulators, horse collar BC's and twin 80 tanks with a solid bar manifold and no octopus. Step back in time to equipment used by recreational divers in the early 1970's.

The first diveshop I worked at we were instructed to check the condition of the O-ring on the tank. I would suspect that is how water gets in or there is no pressure in the cylinder and the valve o-ring is not seated. When we VIP'd a tank we started the fill outside the water bath for the first few hundred psi. Before placing in the water bath. When tanks were in our water bath the valve and fill whip were out of the water. Apparently the owner was aware of the issues. I worked there in the late 1970's.

I have an excellent retirement gig for you. Find the most popular dive destination on the planet and open a SCUBA museum and educate the people on the gear and standards that evolved to bring them safety and enjoyment today. What a way to honor those who paved the way for us!

Just recently the plastic mesh holdig my regulator's purge button deteriorated and broke down. No replacement part available... So much for the longevity of plastic regulators 😢 Otherwise the thing still works fine.

Lots of changes we truly do stand on the shoulders of giants in todays diving

Great video as usual. Off the topic... what's the need of the microscope on your desk? Thanks

Hello Alec. How do you feel about putting a little Silicone spray on Mask Skirts for winter storage? I put a little on mine to keep them pliable.

Working on trying to sell my mint-condition Surf Lung now. Original colour box and all!

I love the vintage scuba

can you make a video using a digital manometer to test the cracking effort?
