I'm going with both because if the transmitter were to fail, I do not have to end my dive.

Many tech instructors now accept "transmitters only" for their courses.
I have a question. The pro to having a transmitter and SPG is redundancy, is there a pro to only having one or the other?
I don't care how anyone else dives, but is the one hose amongst all the others really "that bad"?
Not trying to stir the pot, I'm honestly curious.
This has been debated on other threads. To summarize those who don't have a backup SPG will argue that having one adds another point of failure. The high pressure hose, the SPG and a handful of o-rings. In theory yes this is true. In practice it is miniscule. If a high pressure hose, SPG or o-ring is going to fail it will do so upon pressurizing on the boat. These things just don't fail mid-dive. On the other hand a transmitter battery can fail mid-dive. In my opinion that is a far more likely scenario than my SPG failing mid-dive. This is why I've kept my SPG. It is tucked away and clipped off on my left waist d-ring. I don't even know it's there ... unless I need it.
Oh boy, another issue that has been beaten to death on SB. There are many who agree with you and many who disagree.That's a silly question and you know it. Of course I didn't. An SPG failure is far less likely than a transmitter failure. Transmitters are definitely more reliable than they used to be. I've never lost connection to my Perdix AI. However, you are still dependent upon one electronic device with one battery ... the transmitter. That is a single failure point with a failure potential high enough that it warrants redundancy. However, that is just my opinion. Dive however you wish to dive.

That's pretty slick. I have to run hoses on the rebreather for the transmitters due to packaging constraints. Something like that would make setup easier. Where did you find the high pressure T-fittings like that? Might be worth a try.View attachment 653473
I discovered this configuration a while ago on the board and have been diving this for a few dives and I am actually quite happy with it.
