Back-up SPG?

[markrovner]

Being a gadget geek, I bought myself an air-integrated wrist mounted computer -- which I love -- except the day it failed. I thought the coolest thing about the AI computer was that it meant one less hose, but now I am thinking a back-up SPG would not be bad thing to have.

What's the standard practice among folk with AI computers -- do you have a back-up hose, or a back-up reg, or just dpend on that transmitter to do its job?

My Aeris Elite occasionally loses the psi signal, but if I move it close to the transmitter for a second it comes right back... doesn't happen too often. Until, it happens on a regular or longer basis, I'll do without. May be in need of a battery.

yeah i have the oceanic atom AI and if i loose the signal i just move it closer. i don't use it on deep dives though with twins then i use a standard spg.

How much air I have left is too important for me to trust a wireless link. I still use a standard SPG.

I added a SPG & hose to my bag about a month ago,
I dove it today 'cause my vt pro did not make it back from Oceanic yet.
It locked on all 8,s on all lines, after downloading the dives on 10/10.
Today's dive was #50!!!

I, and others I dive with, have had similar problems with our wireless air-integrated comps- occasionally they lose signal. I've had it happen a few times, above and below the surface.

It didn't take long for me to go get a small SPG- I've even recently seen some folks advertise a relatively inexpensive higher-end SPG on Scubaboard.

Mine has come in handy once so far, and it's nice to have when I do my test-breathing before a dive (to see if the cylinder is only partly open) and the Smart-TEC hasn't sync'd up yet.

I keep mine clipped to the bottom-right hand side of my BC, I've also seen them kept on a retractor on the BC Vest.

It feels like a good investment once you need it while on a vacation trip and would have missed one or more dives without it

I feel that my life is too valuable to trust to a peice of plastic with a circuit board and battery I have a wrist mount computer and full manual console this way I know my depth pressure and heading even if my comp fails. Redundancy is the best insurance you can have.

Yes, if you need one, there is a great deal here:

Funny thing -- my good computer gone bad is also a VT pro, also mia at oceanic. Congrats on #50 -- I am hoping to get there some time next year!

My suunto D9 has never failed me. I have used it exclusively up until I started tech training, at which time I added a small spg with a 24" hose on the left post 1st stage. This gives me some redundancy as well as still tracking air consumption during my dives.
