The right 2nd for my necklace??

[bikefox]

I've set my rig up with a long hose for my primary and a neckless for my backup. My octopus is an Aqua Lung ABS which is very awkward when used neckless style.

My LDS has a Sherwood octo that would setup nice, but I don't know if this is a good idea? Should I be looking at a low performing 2nd stage, or is that really what this octo is?

Some people use a detuned unbalanced second as an octo, the advantages are an unbalanced second is simplier and less likely to free flow than a performance second. Others, including myself, prefer a high performance user-adjustable second stage. The advantage is that a user can detune it manually when not used and increase the performance when used.

An octo can either be low or high perfomance. Typically a tech will detune the octo so it is less sensitive than the primary second and less likely to freeflow.

if someone ever gets your primary, you'll be breathing off your secondary for the duration of the dive ... so ... high quality is a must

as to what type, etc. ... i guess that depends on your preferences

i have an ATX 40 second (non-adjustable) and have gone through trillions of OOA drills with it, no problems...

i have primary and secondary regs from the same manufacturer (Apeks) for ease of service

I use TX-50's for primary second and octo if I give up my second and switch to my backup its the same

Bikefox: Sorry, what's your primary? Why not get something from the same manufacturer that you will be comfortable breathing if the smelly brown stuff hits the spinning blades?

I like the idea of using the same manufacture throughout the setup, if you need some service you have one source for parts. *shrug* maybe that's just me

Good luck.

I have An Aqua Lung Titan LX. Maybe I could use a calypso?

I use Apeks TX50s for both my primary and backup. I don't see any advantage in having a different reg on the necklace than I have on the long hose. Why not use an Aqua Lung Titan LX if you're happy with your primary?

bikefox: I guess one question that may be worth evaluating is Why do you want to switch to a bungeed secondary?

If it is because you feel it's a better, safer, more useful setup, the next question may be Where does this setup come from and why did people use it?

I never fully understood why people want to not invest money in the secondary. After all, if it is in use, some serious stuff probably went down and at this point having good equipment to switch too would seem to be the best thing. I think that in a 'standard' OW setup this isn't as much of a consideration, after all the octo is for "the other guy".

Now your secondary is for you to use, so IMO it's best to get a reg that equal in quality. As an example, on my singles setup I used a Z2 primary and a Z1 secondary. Really the same reg, just not as 'cool looking'. Quality of breathing wise, no difference.

On my doubles I added an M1 and use the Z2 on the left post... same idea.

Enjoy your new setup once you've got it.

The answer to the first part of your question is "yes", I like to configuration for safety. Most of my diving (or at least my favorite diving) is wrecks. That's the main reason for the long hose and neckless setup.

I don't have a problem spending money on something if it is that right piece of equipment. I have read it is best to get a piston/non-precision type regular as a backup to reduce freeflow. It sound from these posts that is not the case.

...Others, including myself, prefer a high performance user-adjustable second stage. The advantage is that a user can detune it manually when not used and increase the performance when used...

Agreed. I use 2 identical high performance second stages, both adjustable, with the backup on the necklace dialed down to preclude freeflowing.
