Why is there no alert system on the perdix ?

[Etmutt]

Come on, I m quite surprised, it look like very few people are actually willing to look into the possible added security aspect…

I’m not looking for something that beeps every 20minutes and annoys everyone you might dive with. I’m looking at something customizable that alert life threatening situations.

The only points made so far against it are the cost of the device and cost of development. Valid points, but hardly a deal breaker.

I don’t think this is about tech or professional vs recreational diving at all. It is about safety. Airline industry and (later) Anesthesiology are 2 professional areas that have pioneered the knowledge about operational safety, and even in those environments the use of checklists and alarms is crucial to increase safety. Absolutely zero pilots or anesthetists will tell you that alarms on their monitors are just for “recreational” guys. They are important and some should even be mandatory. Now I agree that it is important that you can customize the alarm, both the parameters that set them off and the type of alert. I agree that the more advanced you are at something the better you can manage situations, you can tolerate wider intervals of said parameters, and having less invasive alarms is normally better. For example different people will want/need to be warned at different stages as they approach their NDL. Maybe some need a flashing alarm with 5min to. Others just need a small vibration with 1min to go. I’m sure others can come up with examples fitting for tech diving. But saying that “I’m so advanced that I never fail and never need an alarm” is to me the first step into creating a chain of mistake that can have devastating consequences.

For me the use case would be for significant deviations. Like if my ppo2 turns at 2, I would like my computer to immediately alert me in every possible way. Would even mind to have the screen turning stroboscopic
hopefully that would wake me up from what ever issue I m having and save a life

The example of the ppo2 at 2 is a good one : very survivable if corrected very quickly, very much deadly if you wait the additional 30s that you took to check your computer because you were task loaded.

Would you care to explain how, outside of rebreather realm, PPO2 can crawl up to 2 without you noticing? If you say task loading or narcosis, you have no business doing those dives in the first place.

I’m diving tech and I would like an alert system.

As per the heading of your post, you asked the SB community a question and quite a few have answered it. You might not like the answers and that's ok, but pissing and moaning about the Perdix not having beeps and buzzes won't make them magically appear. If you really want them that bad get the Teric, if you don't like the watch style then you'll have to get a different brand.

Airline industry

Are you seriously comparing alarms on a dive computer to the alarms in aircrafts?

 

[Filipe Marques da Costa]

I sure am. Or is tech diving supposed to be taken lightly? From the moment there is a risk to life from a mistake I am all for alarms. Being in scuba, rock climbing, airline, operating rooms, driving in the highway, whatever. But I do agree that: 1. They should be customizable. 2. If a computer does not have them and someone wants them just chose another one that has the alarma you need.

Probably the first thing I did when I got my Teric was disable the audible and haptic alarms. No thanks!

Thinking long term here, hopefully for the next big screen computer they do

While I understand that different people want different things, if those alarms are going to increase complexity and pricing, I would ask them to leave it out, TYVM.

I'm in the "no thank you" camp. It would simply turn them off or not use them if they came disabled. If they are going to add anything to the cost or complexity of Shearwater computers, I would vote "NO".

Dive safely, dive conservatively, dive your plan, pay attention to what the computer is already telling you, and configurable alarms are completely unnecessary. If you are so out of it that you aren't paying attention to what the computer is already telling you, an alarm isn't going to make a hill of beans of a difference.

I can’t see why I would care, I have those on the Teric’s and just turn them off, interesting that so many have such negative passion over a feature that can be disabled, perhaps to much ego involved??
