I understand why you might want an SPG, but why would you want to place it so it interferes with the tank valve in case you have to feather the tank?You will want both a transmitter and SPG View attachment 653390
Mine are straight into the bottom HP port. I have an SPG in my bag for a save a dive kit but that is it. Had both fitted for maybe 200 dives, never looked at the SPG.

ditch the SPGs if using transmitters.
Lots of debate on the issue of SPGs as a redundancy to transmitters likely from the days when transmitters weren't as dependable. Conventional wisdom today seems to be to ditch the SPGs if using transmitters.
Did you run 2 SPGs on your backgas or on each of your stage/deco/SM bottles while you were technical diving?I wouldn't exactly call it conventional wisdom. Yes, many do ditch the SPG. However, many also choose to keep the SPG as a backup. Rather than call it conventional wisdom I would say that it is an acceptable practice in recreational diving to ditch the SPG and only dive with the transmitter for pressure. It is also equally accepted to dive with a backup SPG.
If you are doing any technical diving with your sidemount kit you will want backup SPGs. That's in line with the long held "2 is 1 and 1 is none" philosophy in technical diving.
