AI transmitter Placement

[rongoodman]

I usually end up with my arms crossed, unless I'm using a light, so my right wrist with the Teric is towards the left side of my body. I've never noticed a drop-out though.

Thank you everyone for your input.

Like a lot of folks have done, I dive with 2 AI computers (Perdix AI Right arm-Main & Teric Left wrist-redundant). I have an SPG clipped to the lower left-side D-ring of my BP/W.
I have a SP MK25 with the transmitter in the right-side HP port and the SPG hose in the left-side HP port.
I have had really good luck with this arrangement. I have not had any issues with either AI computer dropping signal, regardless of which side they are on.
I do keep a spare transmitter in my SAD kit.

I have the same issue as @Ukmc did with transmitter on left side where I also wear my Teric, but that puts my SPG on the right side which breaks convention and my right side now has 3 hoses. I originally did this to follow the Shearwater instructions of same side and was used to wearing a watch on left hand. I think I’ll switch the transmitter and SPG so it is more DIR, but I’m a little worried about someone grabbing the transmitter instead of the tank handle. Have others had a problem with that?

Wow, an old thread. I posted this asking a question after having only a few dives with Teric and an AI transmitter.
Well, now I have 5 years of experience with it.
In this time, I have never lost a signal cis or trans positioning. I moved on to a 6 in or 9 in hose for a transmitter on most of my setups. I really like it, but I had one hose spring a leak once. The short HP hoses are prone to it, so I know use braided steel.
I see that @lexvil mentioned to get rid off SPG - Lex, I am glad I have not. There was one dive with what I call a “catastrophic” computer failure at depth - SPG/depth gauge allowed me to finish a dive.
I have dove with two transmitters/two Terics, no SPG and this also worked out well (terics on the same arm or one on each). I did not lose a signal on either.

I use two computers, still no SPG.

You could put the transmitter on a short hose, (6"). That will separate it physically and visibly from your first stage.

I had a Perdix AI go belly up a couple of years ago. Circuit board failure. Since I dive with two AI computers, I had zero issues completing my weekend of diving with my Perdix 2.

I moved on to a 6 in or 9 in hose for a transmitter on most of my setups. I really like it, but I had one hose spring a leak once. The short HP hoses are prone to it, so I know use braided steel.

HP hoses are notorious for eventually leaking without really much obvious notice, either the hose itself or the HP spool. I prefer an AI transmitter connected directly to the first stage. I have zero HP hoses on my regs, primary and pony. I do have an SPG (and a backup transmitter) in my boat bag in the unlikely event I develop an issue while out on a charter.

Great info - thanks. So for the transmitter it’s a choice between risking someone picking up the tank by the transmitter or having an HP hose fail? I guess I’d rather not risk the hose failing though it could be managed by regular maintenance and bringing a spare on a trip.

I was always puzzled why AI transmitters are designed to look so much like tank valve knobs. It’s like making a CPR mask that looks like a chloroform rag.

I've never had anyone attempt to pick up my tank by the transmitter. I rig my 1st stage so that the LP hoses are above the transmitter, providing a bit of protection. It would be very awkward to grab my tank by the transmitter given my hose routing.

Also, boat crews these days are extremely familiar with transmitters. Where I dive (South Florida), easily a quarter to a half if not more divers on a given charter are using one. Boat crew easily know the difference between the transmitter and the tank valve.

YMMV. You have to do what you feel most comfortable with. For me, having no HP hose is of higher importance than minimizing the risk of someone grabbing my transmitter.
