Question Regulator recomendation

[BoltSnap]

In Switzerland it seems that every autonomous diver needs two separate first stages.

Autonomous as in "solo" diver? Is this by government regulations/law?

A good reg today will be a good reg 10 years from now. Virtually certain that someone will make parts for popular models if AL ceases to.

If you get a good deal I would take it. If you can't service it at some point in the future, buy something else when the time comes.

It's not as if you're buying a $30k car.

Autonomous just means that you are certified to dive without an instructor. You still need a buddy. And yes it is government regulation.

It was definitely easier to buy a 30k car haha

As a fellow overthinker, sometimes you have to settle for good and enjoy what you have.

Diving should be more about the experience than the gear (though I am guilty of it as much as anyone).

I haven't seen it yet in this post, but I highly recommend buying two identical second stages. When sh*t hits the fan and you need the octo, you will want it to breath just like your primary. The difference just adds to your stress level under those conditions. If it were I, it would be two Mk19s and two G260s, hand down without any hesitation. The S600 are nice, but you won't tell a difference in breathing. I own both and can't tell the difference when diving. Identical second stages also helps with stocking rebuild kits later when you start maintaining your own equipment. I know, that is not your plan, but at some point the costs will entice you to do it. I only recommend it if you are detail and mechanically inclined. Even if you don't rebuild, you should know how to adjust your regs. Learning one is easier, although not much different. Regardless, acquiring identical rebuild kits is much easier for you or your LDS.

Out of curiosity, rather than two first stages on the primary tank (which seems bizarre!) do the regulations allow for a pony bottle with separate regulators? I would much rather sling a 40cf (5.7l) bottle for redundancy.

Then I would buy a couple of Mk17s and a trio of G260s, or maybe a C370 on the pony.

It just sais 2 separate first and second stages. They can be on the same bottle or two different ones

You should absolutely go for a pony bottle on a sling. This is a much more useful and practical setup. A 40cf/5.7l bottle is also neutrally buoyant so you don't notice it when diving. I always dive with one.

It's all about the tuning -- sadly, far too often, piss-poor tuning -- and I've made more Poseidon coverts in the last ten years or so, especially when they've had a chance to use my setup, which is serviced in house; and I also use the XStream first stages (4751, etc) with Jetstream, Cyklon seconds, and a full face mask.

The sensitivity of the XStream or Jetstream second stage (the guts of which are almost identical) can be tuned, anywhere from 28-40 mm w.c., just by screwing the valve tube towards or away from the diaphragm, depending upon the desired setting, with a hemostat.

At the low end, it is more prone to free-flow but very easy breathing; and at the upper end, sucking through a bamboo straw at 10 meters -- simple choice . . .

I owned old Jetstreams (before the bronze logo), with the divider plate in the mouthpiece tube. I tried an Xstream on land, but did not dive it. Are the Xstreams and Mk3 Jetstreams smoother than the old Jetstreams, or are they the same when perfectly tuned?
