Why does everything need an APP now I have to remember my analyzer and My phone and try not to drop my phone on the wet deck or overboard on a rolling dive boat. I'll keep my Analox with the readout on the unit. On a side note I allways bring my own analyzer so I don't have to rely on the shop or boat to have one that is accurate with good batteries or share with all the other divers. (somehow it seems to amaze others that I have my own?) I just got back form a trip and i brought a gereric CO meter with me as well as I didn't know if i could trust the air.
Indeed, i don't see any benefit in not implementing a display in the analyzer. It just slows the user down to have to use your phone. I rather don't take my phone on a dive boat at all to eliminate any risk for accidents with it.
I'm getting app tired too! Makers go with what the majority of consumers want (or think they do). Give it a few years and we might swing back to fully self contained analysers. A
Hi Alec, it is probably just the old guy in me but does everything in this world need to have an app on your phone? It just strikes me as another thing to get damaged in your dive bag, I recall seeing a few funny fails where people have their phone to take a picture of the fish they just caught only to throw back the smart phone instead of the fish (if it was that smart it should swim back to me!) or did the battery just die? Take care Owen m
In this case making the device app driven moves the logic portion onto the phone, which everyone has, reducing the cost of the device and improving its reliability. It's not for everyone, I hate apps, but this device is far more compact and robust as a result. Think of this as a spare, or for travel. Many people have multiple analyzers, depending on what they are doing. I have a Divesoft HE/O2 for trimix, and Analox O2EII for fast checking nitrox, and a DNA for travel.
Agreed. App & smart phone all work great in the dive shop, but when you’re on a dive boat in 3-5 ft swells like here in California or Hawaii, and checking refill or a new cylinder’s gas, you just want one easy handheld device.
@@NorthWoodsDiver The logic is in the analyzer. A 02 analyzer it is nothing more than a (mili)Voltmeter with a scale in %oxygen. No need for fancy Bluetooth connections to a phone. KISS keep the display on the device.
Others have commented on the APP for everything we are in. Thing is we remember when there were no apps, or dive computers, or BC's or SPG's (sorry, getting carried away). Someday soon i hope makers go with self contained devices, no phone/app/connectivity, just so it works anywhere you need it. A
A couple of notes, the sensor isn't included by default. Many shops package them together, but you need to check before purchasing. Also since the DNA doesn't have a display I think the best way to use it is to get the connection hose and the inflator flow limiter, that way you can just hang it on something and look at your phone until it stabilizes At least based on the one I tried locally. That being said, I prefer ones with displays as then I only have one thing to juggle. Though it is nice to see the sensor voltage, it really gives you some warning as the sensor is dying. Instead of others where it reaches the point that it doesn't calibrate anymore. It is a good option, but not really for me.
@@AlecPeirceScuba_SeaHunter The Palm O2 is probably the easiest to use analyzer right now. You get the inflator adapter and you can just hang it off the inflator hose hands free watching the LCD screen until it stabilizes. I just wish there was a way to see the mV as often the only way I know the sensor is failing is when it can no longer calibrate on oxygen.
I found in my world travels that not every place is a diligent, and safety aware as in the USA and Europe. Best to have your own protection for safe diving. A
Any devices that will tell you if your air mix is contaminated? For example, if the air compressor takes in exhaust fumes and puts that in the tank. I'm guessing if the O2 level is good, you should be ok. Just wondering if there's something better.
The contaminants in breathing air happen at parts per million sorts of levels, typically, making analysis for them difficult. Typically this is done at a laboratory using gas chromatography or a spectrometer which are both complex and expensive. The only analysis instruments for divers measure oxygen, helium, and carbon monoxide. However, scuba businesses selling breathing gas should be sending a sample to the laboratory every 3 months. Usually for about $100-300 per test. This will tell them if there is a problem with the compressor/filtration system Hopefully before its a problem.
There is no way an individual could determine if a fill was contaminated. Only way to know is to ask to see the fill operators air quality certificate. Look back in my videos as i did two on air quality. A
I have used a generic CO meter I bought on amazon it reads down to 1ppm I usually keep it in my garage when I am running the compressor but I recently took it on a dive trip as I was unsure of the quality control of the dive shops. My philospohy is even if the meter is not super accurate if it senses anything then the CO level is unacceptably high. (the CO limit for scuba air is only 2ppm)
these analysers rely on a calibration and to what I see, there is no periodic calibration on these so the reading can be questionnable, excellent topic as usual, excellent video.
I have the DNA. It’s good. Would be better if there was a tube to connect to the yoke valve. Works great. 1) using the phone app is not a problem, but a conscious choice before buying. I finance it a lot if thought and decided it would work for me as I check all my tanks and before boat leaves harbour or before tank leaves shop, so no issue. M2) if you know of CCR divers, reach out to them as they would have 1 year old sensors that you could get at a discount or free.
The one thing I was told about PADI is, They keep you coming back for more Classes. As everything is a "Specialty" course. I recently did AOW, To find out they only go to 65 Feet. I was wanting to try 100.
@@chrisphilhower6029 What we usually do is just drop down to the 100ft then backup in the warm water, a few min in cold temps w/ a wet suit on shouldn't be a problem, but either way that's not a PADI issue.
Dive shop telling you your mix????, Down here in OZ we have to analyse our tanks in the dive store and fill out a log book that the store keeps a logbook of all Nitrox fills (date, person, cylinder number, O2%, MOD) and we sign it. This record has to be kept by the dive store for 12 months. So before we take delivery of our filled tank we have checked it with the fill attendant then the dive store attendant puts a label on the tank that shows Diver's Name, Tank serial number, date filled, O2% and MOD on the neck of the tank.
In my shop we analysed the tanks and logged them for the diver to ok. They have the option of checking our work anytime to ensure hat is on the tank/log is what they asked for. Good practice to protect yourself just in case. A
Yeah, down here in NZ, we also have to do this. Just like setting up your own gears, it's the diver's responsibility to check, ensuring that the % is correct. When you said that divers have the option to check your work, it sounded like we don't trust you. But this is really not the case. We know that logistically, dive centre can either have a third party fill up the tanks or you guys can do it yourself. This and so many other factors increases the risk of incorrect tank fillings. We can all also agree that having an incorrect mix could cause divers their life. Thus, putting this check and the rigging of own's gear would both save the dive centre and the divers and these should be encouraged. Gotta always love the concept of "backup of a backup of a backup" in diving ... this included :).
Another piece of gear I never thought to acquire for myself.
It's an option if you do a lot of enriched air divining and want to check yours, buddies and others before an important dive.

It’s actually a very simple app and gives you the MOD for different PPO2. I was skeptical at first but really love mine.

Maybe dive computers will be able to do this in the future
Or tank valves will have built in indictors of pressure and O2. That would be cool.
A
apexs has a computer that sort of comes with an analyzer built into it. it requires an included accessory
I also don't like having a phone out at the time when checking boat tanks, it's a very rough environment.
Oh i agree. Just there are fewer realistic devices available for the individual that does not require a mortgage or PHD to operate.

I miss the old handheld O2 analyzer but they stopped making them so we only have what is available. I'm not a fan of phone + boat + water either!

I would never use a fill station that wouldn’t let you analyse your gas. If it’s not what you asked for, that’s the place to find out!
If you're at the Maldives at the only dive shop on the island, it wouldn't be me skipping a dive because they wouldn't let you analyse the gas.

@@jacquespoirier9071 , you use the app to calibrate it.

The shop I use has us check it before we leave. The analyzing station is right next to the door, so there is no reason to not check it.
Yeah but people often dive while being on holiday. I do at least. You never know what places you end up at. Best to help yourself.
@Engineer9736 no argument there. It would be nice if all shops offered it. To be honest, I had considered purchasing an analyzer for that very reason.
That's a good idea for a check station at the door. My concern as a store owner is finding it missing one day! Then its beside the counter.
A
are you supposed to analyze from the tank or is it ok to analyze from the primary once the reg is attached to the tank and the nitrox is on.
From the tank is the typical way as you want a tight seal on the O2 reader. Can't get that from the mouthpiece.
A
is it just me or is the line drawing picture on the outside of the "package"...uhh suggestive? lol
Just unfortunate ;)
Could be!

Basically all levels of certification require additional courses though to be fair
That's your instructors fault. PADI AOW can certify you to 100 ft, if you get the full deep diver specialty you get 130.
@@HKChad That's where I was getting confused. The Water Temp was a Balmy 47F at 65 Feet. Maybe they do it with Drysuit??

@@mikenevils8741I would think it would depend on the mix you're asking for.
You should not need a reg O2 cleaned if it came nitrox ready out of the box.
