Scubapro S620ti, "super-flow" hoses & swivels

[halocline]

I will be diving the new S620Ti this weekend. I will give you my feedback.

Hi ya beav. Can't wait for your insightful feedback!

I use the myflex 40" hose in my regulator and I am going to replace it with the regular rubber hose. The rubber hose lasts longer and isn't any worse in comfort. You will need to use a swivel with either type of hoses anyways.

Appreciate to understand your views much better. I though Miflex hoses were supposed be more durable and less rigid than rubber hoses.

This hasn't been my experience, the Miflex hose is wearing out much sooner than a regular hose.

I'm phasing out all my nylon braided hoses and going back to rubber, sure the nylon hoses are lighter and more flexible, but what concerns me is you can't really tell what condition they are in, they all look new on the outside regardless of age. There have been numerous reports of them failing without any visible external damage/wear etc at least with rubber hoses, save a crimp failure, they usually give some warning, bulging, peeling etc. YMMV.

I'm we'll hear it flows superbly.

And the problematic failure mode is they just stop delivering gas. But you should be able to disassemble and inspect to prevent this failure mode.

Yes, that previous thread certainly gave me pause.

Excellent! Looking forward to your feedback (and hope you had a great dive ;-))!

The improvement of the WOB concerning the S620ti comes only from a different exhaust design in the body that routes the exhaled air in a way that one can produce a sort of venturi while exhaling.

So the improvement of the WOB concerns exclusively the exhale process, which is for 99% of dive profiles of almost no relevance.

Exact what I see for years, SP doesn't try to improve the easyness and smoothness of the inhaling process at least to the level they had reached with the AIR1 and the D-Series, instead they are working on bigger exhaust valves and 'exhale venturi' to impress the customers with better ANSTI Machine results.

Did ever someone of you had problems while diving because of a too hard exhaling?

And the MK17 stays for me substandard until SP gets the lousy balancing improved.........

Can you buy a S620Ti without a Mk25? I had no idea that were being sold separately.

Currently you cannot. SP are restricting sales to "sets" only, with either MK17 or MK25.
