Twinsets - same model regulator or not?

[stargost]

Here's a similar question though. When setting up doubles does one use two similar first stage regulators or two different models from different manufacturers with different performance outputs? Why/why not?

I've been about to ask this question on separate post. I dont think people are using different reg, while indeed, this could be seen as further redundancy (different brand, different first stage like piston / diaphragm). Maybe it is not good looking.

Good idea. I don't think it is entirely the same question (different considerations), but it sounds like an interesting discussion topic nonetheless.

Following the posts about dive computer redundancy, the different reg (brand / piston vs diaphragm) for double tanks showed up.

What do you think ? Use same regs because it looks better, or any benefit / drawback of using 2 different regulators for primary and backup in case of doubles ?

Looks shouldn't enter into the equation, unless your worried about an open casket.

I use the same regulators:
Same maintence schedule
Same costs
Same breathing feel

A downside is they have the same potential "weaknesses"

There are plenty of valid reasons for or against.

Looks certainly enter in to it!

For my doubles setup I use a pair of MK25 first stages and a pair of S600 second stages.

As for why ... well, I got a good deal on 'em at a close-out sale ...

Looks, in the box and use what you have. 90 deg firsts. Bottom Lp port is great. I use old Poseidons and Mk 10s with a mish mash of seconds. Looks.

I am leaning towards two of the same on my doubles. Up till now I have had different regs and it presents a problem with service. I have a poseiden odin jetstream, a Mares M42T with a proton metal and a scubapro MK25 with a G250V. I have to take them to different places to be serviced and it is a pain. I recently got a good deal on the new Haycon (mk 25 with a blue cover) and am waiting for that to arrive. That will give me two (scubapro ) regs and hopefully make service life easier. It also makes hose routing more consistant and I will be able to rotate the regs and get equal use on them.

I have a pair of XTX 200's makes life easier for servicing plus it looks good

I dont dive doubles yet but I have enough regs for 2 double's set's. BUt when I do go to doubles. I will be using my Atomic Sealed M1 on one side. And my Scubapro MK17/G250v on other side. I dive cold waters on the northeast and have a little more faith in my MK17/G250v as it is a true sealed reg as compared to Atomics Sealed piston. I have yet had the Atomic free flow and have been in waters down to 40F. I do have 2 sets of the M1's But that would be my choice. Both are great reg's great breathers.

I have seen divers use different reg setups just because that's what they have at the time. I believe that most Tec guys end up going with the same regs because they want the same performance and breath-ability with which ever one they are using at depth. There is also the cool looking factor...LOL. From a service stand point if you have the same regs then you can bring it to one shop and on the same cycle.

I ended up getting two new regs for my set of doubles...Flathead VI. My single tank set-up has a yoke valve while my doubles are DIN. So going to two DIN reg set-up made sense.
