Yeah. That is my plan short getting a backup. Do you bring a backup? How many of you all dive with a backup?
Dive Computer Opinions integrated or no
An air integrated dive computer means one gauge to look at, not two (e.g.: depth, dive time, NDL, amount of breathing gas remaining). One that logs your dives for download to your computer (or smart phone in some cases, I imagine) back home can log your start and end air pressures, calculate...
I've been diving with a backup computer since 2006, 1966 dives. In that time, I've needed my backup computer for 2 dives, 0.1%. This was my fault, as I let the battery in my primary computer go dead.
I dived a backup SPG to 1 AI computer from 2010 until 2019. I still dive the SPG but added a 2nd AI computer. Both AI computers run off a single transmitter. In those 1686 dives, I have used the SPG on 12 dives, 0.7%. Six of those were my fault, the 2 dead battery in my primary computer, 2 dead battery in the transmitter, and 2 dives where I forgot to transfer the transmitter to another reg set I was using. Six were not my fault, 5 transmitter failure and one where I had to borrow a reg set on a boat because my 1st stage was leaking badly from the ambient chamber.
So, I've not used a backup computer or SPG many times but have never lost a single minute of diving. It could have had much more impact had I been without backup on one of my liveaboard trips or on a more remote land-based trip. I have no intention of changing my current setup, you never know
