Question about 2nd stage vs octopus

[shadowboxin]

is there a difference between a 2nd stage reguator and an octopus? Are they both connected into LP ports? is a scubapro R295 regulator the same exact thing as the R295 octopus? trying to figure out why the octo sells for $25 more. Is it because its yellow? thanks for your time

 

[seoultrain]

yes it is because it is yellow but also I think because the octo is longer

the octo tends to be set up to breath a bit hard, I guess to prevent free flow. Both are connected to the LP ports.

What he said. Also depends on manufacturer, some make their octopus' exactly the same, except for color of faceplate, others make them somewhat de-tuned and use less expensive materials. Ask your local tech he might know. I personally am against the use of octopus to begin with, but this is practically a trolling to start a discussion why.

The only difference for a Scubapro second stage of any model versus an octo version of the same model would be the hose lenght and the way the reg is adjusted, internally they are identical.

Well since you opened the door....do you want to elaborate?

He he, i got you. I dive using hogarthian gear configuration, and use no octopus. There have been soooo... many fights and discussions about it that elaboration on it would be useless or some might view it as trolling.

Off the topic note: Love the signature

^^^^

no secondary air at all?

i use Apeks XTX50 on a 7" hose, and oceanic Delta 4 second stage as backup regulator on a 22" hose. If needed a primary reg on a 7" hose is donated to an OOA diver. I switch to the backup in this case.

 

[DA Aquamaster]

One of the concepts is to use a backup that is at least equal in quality to the primary, since you will be the one using it if things go south. Many octos as marketed are cheaper second stqages that do not offer the same performance as the primary.

A variation of this is that some technical divers will use a balanced primary but an unbalanced secondary in the belief that two different regs will not share the same failure modes. I won't comment on that flawed argument (ooops, I just did) other than to suggest that care needs to be taken to ensure the unbalanced backup has enough performance to do the job.
