What's the point of having a hoseless air integrated computer if you're going to keep the hose for SPG anyway?
Added safety... of course I don't see the point of the hose-less air integrated computer in the first place.

What's the point of having a hoseless air integrated computer if you're going to keep the hose for SPG anyway?
Hey everyone!
I just completed my confined water dives and with any luck I'll be doing my OW dives within the next 2 weeks. Woohoo!
I know this is an equipment question but I thought I would try here first in case this is a really silly question. Anyways I have been looking around here and there at dive computers and I like how the air-integrated computers operate, like the ProPlus II. Seems convenient to have everything right there for you to see on one screen. Maybe I'm being over cautious, but I got to thinking that it might be a good idea to have a spare analog SPG + depth gauge hooked up also in case of o-ring & battery failure. Does anyone do this or am I just over thinking? Is it even possible with most 1st stage regs?
Perhaps it's from years in working in aviation, but the thought of having an analog guage as a backup to me is just good planning. Aircraft have analog pressure guages that work when you have full failure of all electronics, and I have my analog guages right there in case my computer decides that it's time to go.
Personally, if I am only 1/2 done with the dive and my computer goes away, I see no need to surface immediately as I can finish the dive with my analog guages quite easily. Then I can record everything on the ole book, plan and execute the next one... If I had no analog backup, guess I'd still be okay to get to the surface, but then I would have no way to do the next dive without borrowing from somebody.
How will you properly plan your remaining dives and keep proper track of you inert gas loading under your proposed plan? please elabourate.
Stop and think through the problem, and you'll come to the same conclusion. Not doing the next dive (for 24 hours anyway) is not a tragedy - just a safe and proper practice underr the described circumstance.
UNLESS you had been diving tables (and then why have the computer), you MUST abandon all diving for a period of 24 hours (per table rules) to get back to a known saturation (for the puropse of table diving - or even to go to a new computer for that matter). Once you've established a new know basis, you can finish up diving.
Continuing a dive (under the portrayed AI computer failure) without a full set of gauges is a foolish thing to do. The proper and prudent procedure would be to abort the dive, get to a know state of saturation and pick up the diving from there.
You can do what you want - but the proper procedure (as I described it) is a well thought out plan for such a case. But you can obviously do whatever you want...
All the best,
Jim
Umm, no.
Seeing as how I have planned the dive to begin with, I know what the expected depth and time are, I kept track of my depth (analog), and my analog guages kept track of the time - I can easily put this information into the tables (and if they allow) continue on the day. I do dive a full set of analog guages and my computer. I do not advocate other.
It is extremely easy to 'bust' the tables this way, and then I agree with you, I am done. However, if, based on time and depth, I am still 'in-the-zone' so to speak, then I am good to go. I tend to keep track of where I have been and how long I have been there.
So, there is some truth to both of our posts - but there is nothing that says I MUST do anything.
While this is NOT my primary reason for analog guages, it is one of the benefits.
Now, where I am screwed is typically if the failure occurs on the second dive of the day, mostly becasue I am almost guaranteed to have 'busted' the tables according to times, depths, and square profiles. then it's 'out-of-the-pool' for a good 24.
