This adjustable Huma inline regulator has taken a hateful procedure out of my range time. If I want to tether I now longer have to worry about how far I fill my tank, I can fill it to 4500psi.

The downside is that if you have a scba tank with a cga347 valve you will have to replace the valve with a din 300. Which I did on this tank here. 

All my guns have regulators, but if yours doesnt, and you want regulated shot strings this would be awesome.

The Huma is tiny compared to those $400 monstrosities, and breaking off gauges isnt as big a worry.


 
That's one is on my list but prob not till next spring. I fill my old scba tank to 250 bar and use it to tether directly. Once I replace the window I broke in my cave (within the garage) I'll build a secure place to house a tank that my compressor hose can reach and my tank hose will reach my guns pointed toward my 10-75y range. as well as my 100-150y range.

The only downside is that the volume is relatively small so it's not as consistent and doesn't repsond as fast as the big units, but very portable nonetheless as you say!

I hadn't thought of it this way. Here's my thought process... Gun's fill pressure is 300bar max (Vulcan), reg in the gun is set to 130bar, external reg is set to 200 bar. I can't imagine why I'd ever worry about refresh rate. That's in a reg'd gun. Now if I was going to use this as an external 'regulator' for a un otherwise unregged gun, then I get your point, but there is still the entire volume of the guns tube/bottle to help mitigate any fill lag. 

Honest question... am I missing something???

I'm guessing his point would come into play on a non-regulated gun, shooting at a fast rate of speed. 

I would also bet the larger units may be more accurate.

I have mine set to 200bar, my guns reg us set to 140ish bar, and I have a 4800cc tank on my Crown.

It's perfect for that application.

My experience this applies when using it tethered to a big bore rifle that does not have it's own internal regulator. It is perfect for Val's application or tethering to a small bore un regulated gun.

I've been using the Altaros version for about 3 years, It's adjustable but must be removed from the bottle to change the output pressure. I use the same pressure for both my guns so it is set and forget. The inside of the reg. is the same as their internal models. I assume that the Huma is the same. The refresh rate is instant and a non-issue. The Altaros unit is also quite a bit cheaper than the Huma and includes the hose. I would recommend that anybody looking for a cheaper, quality alternative, to take a look at this one.

Always good to have alternatives, and competition among manufacturers.

I'm not sure that set it and forget it is a bad thing in most cases either. Huma has a slightly cheaper version that is like that.

I chose the Huma because one of my vendors deals in them, and of course until I get another one, I sorta need the adjustability to support more than one gun on the fly.

I do like that Alteros includes the hose for sure. Nice touch, and makes it a good value

Hi JCD, if your guns regulator is set to 130 bar, then you should be running an external reg at just above that say135-140 bar, running it at 200 will serve to make the external reg work much harder and less accurately.

I think it would be the other way around, or equal in "work". In the "accuracy" part it may be a bit more "inaccurate", who would care since it would be no where near the gun reg pressure and would have no effect on it's accuracy. If your regged gun has 200bar in it or 199.5bar in it would this be seen as any difference to a reg set at 130b? Basically the air tank in the gun would be the plenum for this regulator, right? This reg would keep the gun cylinder at it's (the reg's) set pressure. If the reg is set to the pressure of the guns regulator then the inline would open on every shot, right? To keep the gun cylinder at the reg pressure. If you set the reg to double the gun's reg then the inline reg might also open on every shot, if the reg is able to change on 1/2 as much of a pressure drop, or it would only open on every other shot possibly.

I really dont know how much the bottle pressure on a regulated gun affects the accuracy/harmonics/operations of it when used in normal operational parameters.

However, it seems to me that if you hunt, or shoot untethered a reasonable amount of time, you would want to set the inline regulator pressure higher than you might need to if you only shoot tethered from the bench.

I can fill my guns to 250bar max so after hours of research, and thousands of hours of super computer analysis (ie:random wildass guess, and where the gauge was positioned) I set the inline reg to 200ish bar.

That way when I'm untethered I wont be shooting with a significantly different pressure than I usually practice with.

If I'm honest I suspect it makes little difference for the way I hunt, or shoot, and I am making an effort to avoid getting too far down these rabbit holes that I used to obsess over.

I bought the Huma gizmo because I hate having to stop shooting to air up my gun. The only other thing I really need is a mag that holds a whole tin of pellets, and is of course self loading.

This was my thought also in dealing with any accuracy changes vs un-tethered.

BTW - if you have more then just a single tank you could also buy the below instead of changing all of your valves to DIN300

I have 4 CF tanks, plus a 430cf storage tank...lol

I was unable to find that adapter when I was looking, dammit!

I will get one for my storage tank, but now that I have changed over to DIN on 2 of my tanks. I'll probably do the same on the others, if only to save a few inches of stuff hanging off the tanks, and for consistancy sake.

Oddly enough I prefer the scba valve, but dislike chasing down the adapters. I had to initially buy an overpriced DIN to QD adapter for my Daystate compressor, and that sure annoyed me.
