I used to dive with SPGs but have since made the change to dual transmitters with my Perdix AI. I have never had a communication issue between the computer and the transmitter.
I love it for all the same reasons @tbone1004 stated above. I only use it to see remaining bar in my cylinders and in SM it is an absolute dream. No need to reach back to grab the spg. I just take a quick glance at my computer.
I have had multiple spools blow out but never a transmitter failure. If I did, I would do the same thing a diver using an SPG would do...I would thumb the dive and begin my ascent.
I believe Shearwater changed the game when it comes to reliable WAI.
