Why can we not mix first and second stages from different brands?

[CAPTAIN SINBAD]

I have had the opportunity to use a Scubapro first stage with an Apeks second stage and the combo worked perfectly fine in cold waters of New Jersey. Is there any real (technical) reason why we should not mix first and seconds from different brands or models? Or is this a sales driven ideology intended by companies to ensure that anyone buying a Scubapro first stage should not go out and buy a different model of second stage?

Only issue I can think of is a service issue if you are trying to keep warranties active and one shop isn't "authorized" to service both. Otherwise I'm quite sure a second stage can't tell the difference between 120-140 Scubapro PSI vs. 120-140 Oceanic PSI

Exactly. Tune the second to the first that has a proper IP setting and there is no issue.

I have mixed stage brands for decades.

Same here. I currently use a Scubapro first stage with Beuchat second stages.

Exactly. Tune the second to the first that has a proper IP setting and there is no issue.

Thank Heaven, I thought I might have to go find matching seconds for regs.

Same here. Atomic Z3 and Dive Rite rg3000 Octo, just in case.

It's a sales pitch for a package deal. Buy them together to save money.
It's like skiing/snowboarding, you bindings/board/boots don't have to all be the same brand, find the ones that fit you the best, you just find the better deal when buying new if you buy as a package. As far as service I've never had a shop that couldn't service multiple brands, but YMMV.

I have never seen matching regs on my buddy's rig. Sherwood, Apeks, SP even poseidon. On his doubles 4 different stages 4 different manufacturers he proved you can mix them

as others have said no problem. OBTW, I loved living in Woodbridge when I was at HMX Quantico.
