Do you still use a SPG with a AI computer?

[outofofficebrb]

To each their own.

Yes. I have AI with my computer on my wrist and I still have a SPG. I like the convenience of AI but like to have a backup. I also dive with a backup computer but usually only when on a dive trip/liveaboard with back to back diving over multiple days where I would hate to have to sit out dives due to low batteries or a computer that decides to crap out on me or other unforeseen issues with it.

Is a real pain in the butt to try to bring and SPG and a transmitter out the left side having to take a high-pressure hose and bend the U-turn into it .
I wonder why the manufactures won’t allow 4 feet instead of 3 feet it would seemingly only present a problem if you were driving and holding hands or hugging your dive buddy .
Shearwater wants $350 for a transmitter it’s good for 36 inches . Just saying
Is there a Y connector or adapter available?
I would love to be able to attach the transmitter on a short hose and security with a piece of innertube To the SPG hose

If you want absolutely have both on the left side you can use an high pressure port adapter that provides 2 exits. Xs scuba has a couple of them.
Optionally you can search for a short hp hose (20-25 cm) that are flexible enough to do the U-turn (they are often kept in the U shape using bungee loop in the stages).

If you MUST have your computer on your left wrist (defying all logic for monitoring depth at the same time you control your buoyancy and possibly also control the buoyancy of a "victim" you are rescuing), and you are willing to put the transmitter on a short HP hose, then running it from the right side of the 1st stage, over your RIGHT shoulder, and under some inner tube at the top of your right shoulder strap should be fine.

The reason they want the transmitter on the same side of your body as the computer is so the signal doesn't have to penetrate your head and torso to get to the computer. If you mount the transmitter when it's on your front side, it should reach your computer easily, no matter which arm the computer is on.

And, honestly, it still works very reliably on the right, with computer on the left. I have run mine that way a few times by accident, and also sometimes when I wear my Perdix AI and my Oceanic Atom at the same time. When I wear those at the same time, I put one on each arm. They both receive from the same transmitter. Being on the opposite side just means every now and then I raise my arm to look at my computer and see that it had lost connection briefly while my arm was down wherever it was. Once I hold it up to look at the computer, it reconnects immediately. I might have to wait 1/2 a second to see my tank pressure. No big deal to me, at all. When I download the dive data, I can see that it never loses connection for more than just a second or so, it seems.

I dove with both SPG and hoseless AI for a few years. Eventually I put the SPG into my save-a-dive kit and began to enjoy one more benefit to hoseless ai; one less hose.

My experience regarding left/right mounting of the transmitter is similar to @stuartv. It doesn't matter a whole lot.

If you MUST have your computer on your left wrist (defying all logic for monitoring depth at the same time you control your buoyancy and possibly also control the buoyancy of a "victim" you are rescuing),

Assumption 1: During most of the dive I have a camera in my right hand.
Assumption 2: With my vision I like to move the computer closer for reading.
Assumption 3: Use right hand for anchor lines ascending and descending.
Assumption 4: Right shoulder is better than the left so in bouncy seas prefer to hold on to the hang bar with the right.
Assumption 5: Use the pull dumb for releasing air so left wrist is always nearby.

Logical Conclusion: Put both computers on the left wrist.

 

[Flycaster]

I guess I will just mount the transmitter on the opposite side let it go that way as the only function is to monitor freshener from time to time .
I don’t want my computer on my right side as I do most of my digging probing and just work in general with my right hand

If you have two computers, why not have one on each side? I see your logic and raise you one! ;-)

Also, I put my computer turned a bit to the inside of my wrist. I started doing that after taking Rescue and noticing that I needed to do that in order to see my depth while holding a reg in a "victim's" mouth. But, it turns out it also lets me read my computer when I'm holding my camera out in front of me, or holding onto an anchor line or hang bar with that hand. And it seems like I'm less likely to bang it on something when it's to the inside of my arm versus on the outside where I would normally wear a watch.

You're a Divemaster, so you've taken Rescue. If you found yourself needing to take an unresponsive diver to the surface, would you be able to do so at a safe ascent rate in the configuration you use? I don't feel confident in my ability to do that without being able to monitor my computer. Sometimes, the viz is so bad I can't tell if I'm even going up at all without looking at my computer - unless I drop enough to build pressure in my ears.

Camera is on a long leash hooked to the right. MY personal goal is to avoid all entanglements. Reel and SMB are also on the left hooked at the bottom of the pony. I know where everything is and can quickly and easily get what I need.

yes, Takes one minute to shorten the camera leash and it is slightly buoyant and rides behind my right side.
I also monitor my computer for essentially all assents.

I see no point in braille diving unless looking for something special. So I would not be there. Note that I no longer assist in courses. I also have a low opinion of OW training dives in very low viz. Often all they learn is a card. Now some tech courses is possibly a different story.

I was diving with 2 AI computers (one on each arm) and a console with compass. The entire console (SPG, depth gauge, compass) was doubly redundant (or would that be redundantly redundant) so it is now in the SAD bag along with spare transmitter. I have the transmitter on left side, same as primary computer, but have had it on the other side without any loss of signal to either computer.

I totally agree with this. I LOVE the OLED of my Perdix especially on night dives.
