regs for stage

[liamm]

i should hopefully have a tec course coming up in a few weeks and need to put a stage bottle together.

currently i use scubapro r290s mk17s on my twin set, i am thinking of changing one to a scubapro s555 and using the r290 on the stage bottle with a scubapro mk2

can anyone see a problem with this setup?

There are 2 schools of thought, one says that all regs should be interchangable, so you have options if one fails. Provided you only screwed them on hand tight in the first place.

The other school of thought is that you should be able to distinguish your regs by touch, so you will always know which one you have in your hand.

I go for the interchangable method, all Apeks

i prefer the idea of interchangable regs as well and so will probably stick with scubapro for now. Not sure how easy it would be to change them at depth but i suppose you would have the motivation

no problem at all they will do fine

i might add i have a Mk16 T.I.S 1st stage with Agir brokk stage pressure gauge and R295 Scubapro 2nd stage for sale £125

Hi Liam,

What you propose would work just fine. However, one thing to think about is this. If your decompression time gets quite long, then a high performance regulator on the decompression cylinder can be beneficial, as it will be nice and easy to breathe, and aid lung ventilation on your decompression.

The performance is not quite so important for the backgas regulators as the helium makes any regulator work very nicely at depth.

sorry i should have said, i'm just starting tec - advanced nitrox and deco procedures so havnt moved on to trimix.

i'll pm you about this

TIS (Thermal Insulating System)
When designing a diving regulator, an engineer must bear in mind that this regulator will be asked to perform in all possible conditions. These conditions can be drastically different, such as a Red Sea or a Caribbean dive with warm water and high salinity or a dive under ice in a high-altitude mountain lake. One must remember that a regulator is a cold-generating machine like a refrigerator. To fight freezing problems, various solutions were proposed by manufacturers such as sealed chambers, continuous bleeding systems, and also grease filling.

Recently SCUBAPRO came on the market with a revolutionary patented system that efficiently fights freezing problems. This system called TIS (Thermal Insulating System) is based on heat transfer and insulation. All cold parts are efficiently insulated by bushing inserts and special ice repellent coatings. The TIS system has successfully propelled SCUBAPRO first stages to a new level of cold water diving safety never reached before with conventional protection systems.

All SCUBAPRO regulator systems include TIS and are CE approved for cold water diving. Some models go even beyond this super stringent qualification and have successfully been tested in extreme cold diving conditions at less than 2° C.

there you go

Cut and paste works well from the Scubapro website mate.

Mk25AF...I believe the AF stands for Anti Freeze...is the only reg thats ever freeflowed on me. 4 degrees in Stoney...and no I didnn't breath it at the surface.
