Decisions on a Dive Computer

[BoltSnap]

There are general trends, but nothing quantifiable. Honestly it is more a bit of snake oil marketing than firm science.

There isn’t any.

Do you really want SP to read this libelous attack from the owner of a competing vendor. Do you think that your words have any credibility since you are a competitor (a little one) of SP and you won't be seen as being a vindictive competitor with grudge and an ax to grind? Have you seen any other vendor do this to other vendor on SB or anywhere else?

 

[BoltSnap]

You have to admit, this is more than just a fudge factor.

You can turn them all on or off or use one not the other, it is up to you.

I actually did.

I was hoping to find references to the peer reviewed research stating how heart rate, skin temperature, and respiration rate impact nitrogen absorption. I didn't find anything of value there for the information I was seeking.

The document was NOT meant to be a scientific research paper to be submitted in a specialist technical conference, it is material for the consumer of their products.

If you want more information, just send them a message through their website. I have done that they respond within 1 business day.

It isn’t libelous. I am merely stating a fact. The fact that there is NO peer-reviewed science and data to backup this claim or ‘feature’ in a quantifiable way.

I am not speaking as a competitor, we have no official presence here.

I am answering Kosta based on my background as a MD with post-graduate training in hyperbaric medicine, and someone with experience actually programming decompression algorithms. So yes, I think most here would realize I hold a good bit of credibility in this arena.

My conflicts of interest outside of my academic qualifications and professional experience are also clearly stated in my signature line, so the reader may make their own determination.

This isn’t an axe to grind, it’s merely me pointing out the feature doesn’t have any real hard science to back it up. When you already apply a significant safety margin via GFs or a conservatism factor, varying it a few percent when it’s already so far below the theoretical M-value is little more than window dressing.

For the record, I would say the same thing about an upcoming new computer I saw that purports to use a sensor to monitor bubbles in the blood. Again, there is no science to quantify this in a way that could accurately modify a deco algorithm on the fly. Read any of the studies where they monitored divers via ultrasound.

Oh pleaaassse

Let us not let the facts cloud the discussion....

Would the same comment on lack of peer-reviewed and published data from @Duke Dive Medicine be attacked? or @Dr Simon Mitchell ?

That's the way I took it. Definition of libel requires the statement to be damaging to a reputation AND false. A true statement, even if damaging can't be considered libelous.

If there is peer reviewed science to backup the HR adjustments, it should be easy to find.

 

[BoltSnap]

Honestly it is more a bit of snake oil marketing than firm science.

So this isn't libelous nor professional for one manufacturer to come out and make these accusations against another manufacturer?

Did you make any research (scientific research) yourself for you to base your accusations on before you made this statement? Did you reach out the SP and ascertain your claims before you let your fingers do the typing here?

 

[LandonL]

You are the owner of a competing company still, your titles in your signature line don't mean anything.

That is for the reader to decide. Honestly I consider myself an MD first, and a dive equipment manufacturer 2nd (or 3rd, or 4th, or 5th, given my other business ventures). I haven't even bothered to mention my company or our products here, I am not trying to sell anything, just having a discussion based on the science (or lack there of).

NOTE: SP can bring other people with much better credentials and experience including specific authority in this specific field than you do and rip you apart but they don't and probably won't.

I am unaware of any other MDs with hyperbaric training and design/programming experience anywhere else in the dive industry.

Also, again, there has been no presentation of any peer-reviewed data to date. Regardless of whatever you think they can say... it doesn't matter without any peer-reviewed data.

And without multiple peer reviewed studies it would be nothing more than opinion.

Back on topic: i own a Suunto D6i with AI and love it. Everything i need i see on one screen. For me this adds to having a better oversight on all values important. Is it necessary? No sir, but i hate consoles, not sure why. I do have a console on my set as backup but never use it. As to algorithms, i defer to people more knowledgeable about this than i am. From a practical standpoint: i have never given a toss because i never had any issues with it. I'm a recreational diver and doing two hour long dives a day to , say 25 meters with a nice interval has never put me close to ndl. Probably a very big deal for other types of divers but not to me. The Vyper is big (very good readability), takes a good deal of abuse and works well (the d6i is exactly the same, just watch sized). Afaik you can never do wrong with any Shearwater. Im not a real fan of the puck or other Mares computers but thats entirely personal. If i had to do it again now i would buy a Teric with AI but i have more disposable income now (again a lot more expensive).

You decide what kind of diver you want to be and pick the goodies to match that and your budget. You can also see if you can borrow some and see what you like.

Have fun diving!
