#ASKMARK Hello Mark, while out diving recently I talked to an experienced diver who was diving with twins but did not have any manifold on them, i.e. each cylinder had a first stage with a primary and an SPG. One cylinder had the low pressure inflator for his BC. What are the pros and cons of a manifold setup versus independent twins?

#askmark if using a transmitter do you still need a spg? I do on my main, but not currently on my stage, a transmitter only, it’s a new setup so after a little advice. Thanks Nick
