Noticeable difference between HFP and regular LP port?

[Joris]

Hi,

Will I notice the difference if I attach a Scubapro G250V to a regular LP port instead of a HFP on the MK17?

I want to turn the body upside-down so that the 'mushroom' with the diaphragm is pointing down instead of sticking out. I have the octopus on the left, and the SPG on the right. The HFP will then be slightly below the HP port, while the regular LP port will be above it, and I don't want to grab the wrong hose accidentally; safety first ...

Thanks!

The HFP is advertised as something like 15 to 20% more flow than the standard port. It is doubtful that you will notice the difference on any recreational dive unles you are working very, very hard.

Not to hijack the thread, but I'm a bit puzzled by your proposed gear configuration. I understand flipping the 1st stage body over, but why put the SPG on the right and octo on the left? There are two HP ports on the MK 17 so you can have a standard configuration (breathing hoses over the right shoulder, all others on the left) with the 1st stage in either orientation.

Thanks.

The standard configuration of the Dutch CMAS (NOB) is to have the octopus on the left side. When I teach I'm expected to comply with this configuration. Something can be said for it I think; it does make buddy breathing easier in some situations.

No its doubtfull, unless you are a breathing machine you will not notice the differance, as mentioned its advertised as having a greater flow, however the negligable differance is hardly discernable on an average dive even in a fairly stressfull situation, I suggest it will be seriously difficult to overbreathe this reg even in a standard LP port.

Not only the Dutch CMAS have this regulation its fairly common in other European countries who teach Cmas as well, I have seen it in France and Belgium to name two.
