Scubapro Mk17

[diablo]

Need some help on this one!
I dive a Mk 17 on my right post with the long hose connected to the high flow port (not high pressure) and the inflator connected to the low pressure port. Unfortunately this means that when the top of the first stage is in a parallel position to the manifold it interferes slightly with the valve knob. I want to turn it through 180*. This will mean having the primary on the low pressure port and the inflator on the high flow port. Will the low pressure port deliver sufficient gas and will the high flow port deliver to much gas to the precision inflator and stop it being precision

No and no just do it! is the short answer.

To answer your second question first, the Mk17 provides approximately half the possible throughput of a Mk25, and hence you can be sure that the use of the HFP will not impact the attached LPI be it "precision" or not. The gas flow available to a port does not impact the pressure which it is supplied at.

You may find that the reponse time of the Mk17 is not as good as a high performance piston reg (Mk25) however it is in human terms more than acceptable ( and I doubt you will ever be able to tell the difference, other than possibly the different sound that the two regs make) with the advantage of being less susceptable to freezing. From a standard port on a MK17 you should be able to draw approximately 5000L of air per minute when the cylinder is down to 100BAR. Given that there is no second stage that can deliver more than half that quantity of gas (air) it is irrelevant.

oppps I seem to have strayed into the wrong forum - please note that the above is a common sence answer not necessarily a DIR one.

Cheers I guess I'll just do it then
