| Hello Jen
I think its always a good idea to have some kind of backup just in case anything goes awry underwater.
I personally dive a twinset and have 2 contents guages, 1 depth guage a watch and 1 computer (Vyper) The one console is a combined depth guage and contents.
If you want you can always have a back up depth guage on your wrist or even in a pocket intead of it being on a hose, but it's a good idea to get one.
