Well, I bit the bullet and purchased a Shearwater Peregrine. My current computer is a hose-mounted AI (Aeris Atmos AI). Main reasons were:
  • replacement for an older computer that is no longer supported (Aeris is no longer in business)
  • wanting a wrist-style for ease of checking depth and NDL
  • ability to set conservatism levels
  • well-known algorithm
  • much better display
However, the Aeris is still functioning well and I am thinking of using it as a backup. So my questions are:
  • My 1st stage has 2 HP ports. Should I have a brass and glass SPG only, or
  • Use the Aeris as a primary for air pressure and a secondary for depth/NDL, or
  • a combination of the 2 above for full redundancy?
If brass and glass, any recommendations on make/model? Been looking at the ones offered by DGX.

Thanks and sorry for the bulleted lists but it helps me keep my thoughts organized :)

Give it a try before buying spg.
But make sure the algorithm of both computer is compatible. You might need to adjust the GF of your SW to achieve that.
 
I loathe consoles. Big bricky things and I see many people let them just float about wherever.
Me too. My plan was to route the hose under my waist belt to the left of the buckle, so that I could look down at the console and keep it tucked away.
 
Brass and glass. Look for a used one, they’re everywhere nowdays! Keep the hose computer around as a backup, no sense taking it in the water every dive though.

the standard configuration is to clip off to a d-ring on the left side of your waist strap. 22-ish inches is what you need give or take based on your height possibly.
 
I'd keep the Aeris if it is still working fine. You can buy a bungee console holder that attaches to a shoulder d-ring on your BC.

Yeah, probably right. For the recreational diving I do, not much need for ultra redundancy. If I didn't sell it I could always bring it along on a liveaboard in case either the SW or the SPG went belly up.
