AI for sidemount

[gmerick]

Transmitters and SPG on each cylinder. Yesterday I was glad I had both. Much easier to check pressures on the Perdix. Perdix will also give a reg switch alarm. But yesterday something went wrong with the Perdix - Both transmitter displays said comms failure at the same time. I was one hour into a planned 1:45 dive. Last pressure reading I remembered was 2000 and 1750. Held the Perdix right next to each transmitter but no joy. Turned the dive, and made an uneventful shore exit because I had SPGs as a backup. Sent e-mail to Shearwater. Changed all 3 batteries. Functioned normal today.
I'll be sticking with AI plus SPG from now on.

Are you using swift transmitters or oceanic? If you’re using a pair of oceanic transmitters they will interfere with each other eventually and cause a comms drop. Replacing one with a swift or a yellow oceanic will keep that from happening. I found that out the hard way…

To answer OP’s question, I dive with transmitters and no SPG and love the setup. I’ve never had an issue since I swapped and oceanic transmitter for a swift.

Hello

I use two transmitters (Oceanic/Aqualung, one grey, one yellow) with two Perdix AI. I did around 400 dives with this configuration. No problem whatsoever. The transmitters are attached directly to the 1st stage without hoses.


Best wishes Jens

I use transmitters screwed directly into my first stages, no short hose. I wouldn't like to dive w/o them. Much easier to check gas for both cylinders at a quick glance, keep track of GTR, SAC, etc.
I do have a button SPG on as well. Mainly to be able to quickly confirm pressures when I'm temporarily charging after putting my kit together.

I have a Grey and a Yellow transmitter. Feedback from Shearwater was possible computer antenna failure. They offered a RMA for service, but I'm going to hold off for now. I will buy a Perdix 2 soon. If I get a repeat event, I'll use that RMA. I dive with an AquaLung i200 as a secondary; the only affected functionality was AI; I have SPGs.

Yes. Shearwater Swift Transmitter on both side mount tanks. No SPG's but do have one in Save a Dive Kit. Also have extra Swift Transmitter. Never had a problem with Perdix 2 or transmitters.

If you had an SPG failure, you would have done the same thing - ended the dive. So if the redundancy of a extra gauge there worth it? You planned your dive and knew your gas.

What nonsense.

Oops, forgot the pic

This is the left reg/necklace reg btw, so just turn it 90ccw for a pov

Those janky swivels are the most likely point of failure by far

Those janky swivels are the most likely point of failure by far

guilty as charged, I get anxious about them as well and I find myself "checking" on them more often than I like

they (the jank) have always been a temporary soln. since I am not finding HP splitters in stock to run them without swivels (comfortably)

I am open to other ideas/suggetions -- within the requirment: I wanna use both a transmitter and (non button) SPG

EDIT: I know it's an eyesore -- I wish I put a trigger warning in the last post
