Nice video as usual. Gave me the idea that it would be interesting if you could talk about what is actually done by the service-technician when you bring your computer or bcd in for service.
"A good diver is always learning" unless if your Alec Peirce and you know everything there is to know about scuba diving. Also very interesting video keep up the good work
Oh I don't know everything, my grand kids think so but I know what I don't know! I'm still learning and enjoying diving and some new gear features amaze me. Take care. Alec
Hey Alec! I love your videos. I have a request. Please make a video about underwater signaling devices such as sub-alert, maraca type devices, etc. It would be very useful to know about your experience with them. Thanks! Hi Kevin! ;)
Look for video S03E06, Noise Makers for Divers. My favourite noise maker is poking Kevin with my reef stick. He makes lots of noise!! Thanks for watching. Alec
Hi Alex! Just want to say that I'm a huge fan. Your series has really helped me with my gear choices (and relieving me of a lot of $ at my local dive store) and feel more comfortable with how everything works. Unfortunately I had a pretty bad issue today where my SPG was reading 800 PSI when I went to retrieve a 30M transect tape and when I returned from the 60M swim to retrieve it, I only had 300. 30 seconds later, I was 100% out and had to share air with my buddy to the surface. The dive shop looked at the tank (just purchased 3 months ago) and couldn't find an issue and my buddy didn't notice any bubbles coming off me. I borrowed someone's backup regs for the next dive and used air as expected without issue. I noticed that my SPG always would read 3600-3800 after filling my high pressure 80s and that recently it seemed as though I'd go through air faster as my tank was getting more empty, but I'd just assume it was due my own inexperience. On this dive, I also noticed that I burned air fast descending from the surface (lost 500 PSI dropping 45 feet). After we removed the SPG from its boot and hose, we noticed that it rattles when you shake it, but I don't know if that's normal. Do you know what could have happened? Is there any way I could have realized that there might be something wrong with my SPG earlier? Hint, hint: a video on early warning signs something might be wrong with SPGs or any other equipment would be super helpful.
Gosh Laura. That's an odd one. If there was no visible air leak, it would be hard to pin down. However, SPG heads are cheap. I'd replace it anyway. Then you know it's accurate at least and can do a better job of monitoring. Maybe it's time to think about an Air-Integrated dive computer. With most of them, you can connect to a computer and see your air consumption throughout the dive as well as compare your consumption over many dives. The SPG head can be loose and shake about a bit when it's not under pressure. If it isn't leaking, it's OK. However, the swivel pin costs about $5. Maybe it should be replaced to be sure it doesn't leak or even blow during a dive. Pretty cheap insurance. Thanks for the tip and for your kind comments. Alec
SPG are not that reliable - dive shop small SPGs by the fill station are +-300 PSI when checking pressures. seems like AI computers are much more accurate digital versions (though I suspect my computer went to 0 PSI which I tested in the pool and still was able to take 20 breaths - maybe build in safety like car tanks.
Thanks Alec (sorry about the spellcheck miscorrection in my original message)! I went ahead and replaced my SPG (and used it as an excuse to buy the air integrated Scubapro G2 I'd been eyeing), but when cleaning out my BCD I realized that it was also leaking, because one of my dump valves wasn't completely screwed on, and only leaking when it was very inflated on the surface (probably leaking whenever I added air at depth) - that probably explains how I lost 500 at the surface and went from 800 to 300, since when we are doing surveys we normally dive a little "heavy" and move down the line very slowly, but must have tried to inflate it to swim to get the tape, initiating leakage that my buddy didn't notice because he was finishing his survey. Then it probably went from 300 to 0 because the SPG was reading high until it was just out. Just goes to show you how many variables can create a synergy leading to a dive incident - SPG reading high, BCD leaking but inconsistently, task loading, and diving in a way that I wouldn't immediately notice the BCD issue the way I would if we were just swimming around.
As a detergent, i use a mixture of water with a bit of vinegar acid (i can buy that as "vinegar essence" at every supermarket) and some drops of a normal dish soap. Does the job perfectly. I don't have a heated ultrasonic cleaner, but a more simple one. I just fill in warm water for better cleaning. (Not only against salt, but also for removing lime with the vinegar acid. The chemical reaction for this is boosted by temperature.)
Excellent content as always, Alec! I service gear for my local dive shop and have occasionally ran into equipment the has been poorly maintained after multiple saltwater dives. What commercially available solution have you found that is more effective in treating saltwater corrosion without compromising the integrity of the given part? In reviewing some of the comments below, I definitely want to avoid returning equipment to a customer that has been over-processed or has dulled the "show room" appearance.

Hi Alec Did you ever thought about, just to clean the filter instead of replace them? I just imagine, in some cases it could be a smart idea, if the rest of the regulator still looks fine. I know if you would clean the filter, you may couldn't have another 100 dives before replaceing the parts, but maybe it would be possible to get 150 dives before replaceing. I guess I would try it. If I could service my own gear, I may would clean the filter, after 10/15 dives I would check it again.
It is a requirement from the maker that all service kit parts be used. Otherwise the customer is getting ripped off. Also the effort, time and cost of an u/s cleaner is much more that most small LDS's might want. A
Hi Alec! Great video! Would you mind sharing some specs about what should I look for before buying an ultrasonic cleaner? What model, size, brand is the one you use in the video and is always there in the background of every video? Thanks!!
90 to 100% of all Ultrasonic cleaners are made by the same companies. My point is that there is very little difference between different makes & models - at the consumer level. Industrial cleaners are different. To be honest, I went online and compared several cleaners that had the features I wanted - a heater, timer, and the right size. I bought it online. I chose one of modest size. You don't need a big cleaner to clean regulators. You're only cleaning small parts, not the whole thing at once. So mine is 2 liters (2 quarts) capacity with a heater & an automatic timer to turn it off when done. I hope this helps. Alec
First use hot, deionised water which is a natural solvent. Then either a commercial product or home made. There is a wide range of cleaning products, some better for metal, others for plastic. Suggest reading all these posts on SCUBABOARD.COM that will answer most u/s cleaning questions. scubaboard.com/community/threads/recommend-ultrasonic-cleaner-solution.610084/ A
O2 cleaning is a completely different process. It's so different that we actually have an entire separate set of tools just for that - a separate Vis light that is kept is a sealed plastic bag, separate wrenches, different O-Rings that are sealed until used, different grease and so on. Everything is kept in a separate drawer and sealed in plastic. Even the rags used for cleaning and wiping are new and kept separate. Since O2 cleaning basically is the removal of all contaminants, particularly grease or oils, nothing used in a normal service process can be used for O2 cleaning. The actual cleaning process is similar. Alec
funny i just bought a small Ultrasonic couple weeks ago to clean an older regulator I wanted to tinker with (practice before doing my main one). Used pure white vinegar on a quick release connector (think stainless steel?) and came out looking like new when it was pretty corroded. Did same on entire taken apart regulator and I think the plastic parts smell like vinegar now :)
Check with the manufacturer as they have recommended solutions or google to find a home made one that you like. Be careful as over cleaning is just as bad as no enough. Glad you like this subject. Alec
Hey Alec, thanks for another great video. One question I have, is how would you clean, besides from replacing it, the small “dry air bleed”sintered filter imbedded in the Sherwood piston regulators, when they get silicone grease, when servicing them? I tried just about everything and does not work well. The closest thing so,far, has been heating the piston to about 700F over an electric stove, to burn off the silicone grease, but I don’t it is ideal. Any thoughts? Thanks in advance.
Those dry air bleed filter cost about $0.16 each. Why are you trying to clean them?? It's pretty much impossible to clean them anyway. When working properly, they get dirty inside and out. A service kit for those older Sherwoods always includes a new dry air bleed filter and the plastic washer too. I have Sherwood service kits for sale on eBay, cheap! My eBay ID is Seahunter. Take care Miguel. Alec
Alec Peirce Scuba the Sherwood I have, the Oasis +, I have to replace the whole piston, and they are about $35-$40 a piece. I have about 3 or 4 with the same problem, with the contaminated dry air bleed, probably not more than 3 years old.
How you get a tank into one I don't know. The biggest u/s cleaner is about the size of a loaf of bread. Tank cleaning is best done by tank tumbling (see my video on this) and a proper visual inspection.
I think google is reading my mind, I cleaned my first reg set today ( aqualung legend lux supreme) for the first time in a tub of water and was thinking about ultrasonic baths
An ultrasonic cleaner is used for cleaning parts if needed during service but you wouldn't clean the entire reg as a unit in an ultrasonic, if that's what you were thinking. Alec
Hi Alex, Do you think it is ok to soak dive computer here with warm water only (or maybe a bit dishwasher cleaner)? Some narrow part between button and screw has a little dirt and maybe somewhere behind the sensor where I can see it. Thanks
To be clear, never put a dive computer or electronic device in an ultrasonic cleaner. It is for metal parts only. Any electronic device can be soaked in fresh hot water (sink or bucket) to loosen dirt and keep the buttons working. If they are stuck, get your local dive shop to fix it. Take care Kresna.
Hey Alec quick question: is a dive wetsuit the same as a surf wetsuit. Are they any different in any way and do they perform differently under water? Thanks!
surf suit are made to be VERY stretchy - the latest Oneil I use windsurfing is so stretchy at the neck area I can put my entire body through (no zipper) . Dive suits are made of denser neoprene so they don't compress as much as you go down (loose warmth and buoyancy). May not matter as much for a thin shorty spring wetsuit
Hi Alex, I just had 2 of my 5 sets of Mk25/S600 regulators serviced by a Dive shop and my second stage body now looks like it's faded or the plastic is damaged. Do you know how this can happen? Should the plastic body of the second stage be put in the ultrasonic cleaner? I've always taken great care of my gear, so this is extremely disappointing, especially since they said it must be sun damage (is this even a thing with Scubapro second stages?) And I know when I dropped it off it looked brand new. I've left my regs at the shop so I can speak with the Manager next week, do you have any advice on what I should ask him? I have taken photos of them but not sure how to upload here. Thanks Pauline
I sounds like the 2nd stage body was put in the ultrasonic cleaner. If you have resent pictures of your reg before the service, take it to show the change. Talk to the Manager and show the change and if normal, as to see other regs serviced to see if they should all look worse too! If the Manager does not agree it was the cause. Ask him to take a new 2nd stage and put it in the u/s cleaner for 15 mins to prove there is no change. Note, if a u/s cleaner works on metal, it also eats plastic bodies. Try and reach an agreement not a fight. You may need air fills and he may want to sell you something shinny some day.
