HOG 2nd stage arrived today now which 1st stage to use

[shogan]

Well it came today $95 shipped for the HOG 2nd stage new baby. From what I can tell it seems very nice.

It's larger and heavier than my 5000 series sherwood oasis. I don't have a scale but it feels to weigh almost twice

The mouthpiece is very very soft and pliable (don't know if thats good or bad).

Can't hook up to tank just yet but exhalation seems very very easy.

Now comes the question should I pair it up with the

1. Sherwood Magnum 5300 1st stage balanced piston

2. Scubapro MK16

 

[Kunundrum]

Either should work for this second stage, as long as it has a stable IP, (both are balanced 1st so this should not be an issue) I would probably hook it up to the MK16, unless the magnum is in better condition.

I have mine matched up with a Oceanic DX4 and it works great.

Doesn't matter at all from an operation standpoint. As long as the first stage is working properly, both will supply more gas flow that the second can flow. Use which ever you prefer due to hose placement or that you just like better.
While both first stages are balanced, it would not matter if they weren't. The second stage is and as long as one or the other is balanced the objective of balancing is met, balancing both is redundant and unnecessary.

The only difference it would make is where it intermediate pressure of each first stage is set. If the two are the same-it does not matter. So hook it up to each one in turn and first make sure neither will not cause it to free flow. Then either test breathe it or use the immersion-in-the-sink method to determine which combination gives the lowest cracking pressure.

Non of that matters if you know how to adjust the cracking pressure yourself or will have it adjusted by someone you trust.

Here is a link to a regulator checklist a group of us put together. You will find some good hints in it even if you do not have any tools or desire to work on your own gear. The link goes to the latest draft, but the rest of the thread is worth reading too.

Couv,

Thanks for posting the link to the regulator checklist. I was sorry to see the original removed from the "sticky" posts; the new condensed list is great however.

Best wishes.

I was going to ask which was better for dependiblity, etc but then realized that piston vs diaphram is a long disputed debate.

I'll try them both and see which I like.

Hello LeadTurn_SD,

That is actually the expanded and latest revision; but in a single post. Here is a link to the entire thread: http://www.scubaboard.com/forums/regulators/260452-regulator-checklist-inspection.html

I too was sorry to see that "Sticky" go, a lot of people took time and effort to put it together (some who don't even know it )

Couv correct me if I'm wrong (my SP is not that good) but both are piston regs, althought the SP is a flow thru piston as opposed to the SW flow by piston, so there is no debate. I doubt there is enough differnence in reliability to worry about in the real world but in a no holds barred, abuse the dickens out of them test, my bet would be on the Sherwood.

I'm not a scuba pro expert by any means, but I'm pretty certain the Mk 16 is a diaphragm reg.

Same here, I just know the regulators that I own. However, Jimmer is correct, the MK16 is a diaphragm regulator.
