Glad to be on the forum, and glad to be back into paintball afte about 6-8 years. I was hoping someone could catch me up on what has happened in paintball in the past bunch of years.

what is the difference between low and high pressure? i know that low is 450psi and under and high is 800psi and up, but why would i want one or the other? what are the pros and cons? if anyone could direct me to a good write up that would be great.

just to clarify: my OLD school spyder (spyder compact bought back in 99-2000 ish) is a high pressure gun right?

Obligatory welcome to ya RS25! J/K

Erm, it really depends on who you talk to about low vs high pressure. Most people advocate low pressure because they say it is easier on the paintball, so it will break brittle paint less often. Some also say it helps with efficiency, but that really depends on how MUCH air is used per shot too. I mean, if I'm running 800 PSI and use 0.5 CCs per shot and someone else is running 200 PSI but using 2 CCs per shot it's the same damn thing.

I like the idea of lower pressure myself, when it comes down to it though. Some guns run as low as 100 PSI now days which I think is amazing. Technically I could hook a gun like that up to a regular shop air compressor for testing (don't try that at home kids) and though I've never done it, it's a cool thought. In my guestimation, lower pressure means less stress on parts and less need for metal on the gun which means lighter. Most marker companies are going low pressure with their higher-end guns. *shrug* One man's opinion.

EDIT: Some of the older Angels were high pressure though I believe and they were/are amazing markers.

I DIED MORE GLORIOUSLY THAN YOU! in-so-far as i was the last one to die in the new video. j/k

okay so a few more noob questions: i think i know what they did when i bought them (i hope) but what does the expansion chamber do? for that matter what does the chamber under my barrel do?

my spyder is high psi right?

You're the guy who died last in the video? I was wondering who that was. I thought he was running an MilSim A5 with a remote though. Or was that the just kidding part. *I'm feeling a little dense tonight*

I believe most Spyders are high pressure, but there are some that are low pressure like the VS3.

The expansion chamber is where your liquid CO2 gets turned into gas if, for example, you're shooting very fast or turn the gun upside down. Keeps the CO2 out of the gun's internals so your o-rings don't freeze. If you're shooting compressed air, you don't need one.

in regard to the expansion chamber: dont need one or disadventagious to have one with HPA?

what about the chamber under the barrel?

yeah that was me getting merc-ed at the end. i was using chads a5. great gun; but it later occured to me that given the one hopper limit on paint in preditor games it was a bad move. since it also had a MUCH higher rate of fire than my chromagnon spyder i ran out of paint pretty damd quick.

The expansion chamber, as far as I know, will have no effect one way or another on an HPA system. I'd have to see a picture to know for sure what the chamber under your barrel is, but it's PROBABLY your regulator. See if you can find a copy of the manual for your model Spyder online.

Chad's A5 is a sweet setup isn't it? But yeah, any fast gun is going to use those 200 paintballs in a hurry.

Quite probably an expansion chamber on the old Spyder. The older markers were designed with CO2 use in mind. Especially the stack-tube blowbacks (Piranhas and Spyders). They still are, my wife's Spyder doesn't run well on HPA at all.

Oh, um... that's my airsmith hat, isn't it? Forgot I had that silly thing.

I believe he's reffering to the low pressure chamber on the spyder. It's just an air chamber before the valve. It supposedly helps the gun run on a lower pressure.

back to the low vs high pressure. are you referring to the marker or the tank? Alot of low pressure guns still recommend high pressure tanks to combat shoot down. The reg. takes care of supply pressure.
Ion: 150psi opperating pressure ~800psi tank.
