Hello!
Recently acquired an Aqualung i770R with transmitter, so I'm very excited, and been thinking about removing the SPG to reduce clutter once I have some confidence in the transmitter's reliability (I've read the various threads on this topic, and decided that I'm ok with having to abort a dive if the transmitter fails, assuming it happens very rarely).
However, one thing I'm worried about is not being able to do the "needle fluctuation check". I'm not sure how common it is, but in training (BSAC OD + SD) we have always been taught to do a few fast inhales and check for needle fluctuation on the SPG (which would indicate the valve not being fully open). Is that still possible with a transmitter? Or do people just not do that? It would still work if the transmitter can transmit the lowest pressure seen since the last sample time, but I'm not sure if that's how they work.
Thanks
