I don't tend to count on advertizing... including this video by Staun.
The last one to be "bashed" is the 'Mil-Spec Multi Choice Deflator' which I use (pictures in my previous post). It doesn't matter if it stops abruptly or a little bit more slowly, it is accurate.
It also makes noise, so I can hear it stop and know when to remove it.

However, the Staun have been the most copied deflator type, and they've always been better than their copies.
The improved new Staun II is even better (BTW, it's made in the USA).
For increased accuracy, it comes with an extra color-coded coil spring -- use the spring that fits the psi which you use. The instructions make it clear which spring to use.

 

Very true, any video put out by a manf. I take with a grain of salt.

So far my Staun II's have performed great, accurate, quick, awesome, lol. I have routine with them now, when everyone stars airing down I slap these guys on, change out of my flip flops into my boots, get the camera gear out, talk a little, take deflators off, snap a few 'before' photos, and walk around and mingle with all the guys using the arb style deflators while I preach how they should get Staun's

Oh all my mods I'd say the Staun's are one of my favorite, it really frees you up to do what you will (change footwear, pre-put recovery straps on, attach winch controller, move gear around, chat,etc.. ) instead of being stuck attached to the tire deflating one by one.

 

I went with the TF and used them 2 or 3 times and then went with the Stauns. The Stauns are worth the extra money if you are airing down a lot. I keep the TF ones in my bag in case someone else needs them when our group is airing down but you do have to keep a close eye on them.

 

Another vote for the Staun II for all the reasons already stated.

 

Very impressive!!

I ordered a Curry for $30 shipped, which is more than I really wanted to spend.

Seems like most off-roading products out of Australia are really well done. I guess you wouldn't want to be stuck far in the outback with crappy equipment.

 

Here's an interesting article from a couple of years ago on Four Wheeler Network:

The Great Tire Deflator Shootout - Four Wheeler Magazine

 

The fasted way to air down a tire is to pull the core. There is no denying that

 

I know the Staun came out with the II which now has a locking collar and is quite a bit shorter then the original. Not sure how many of the other ones changed over the years. Still a decent article to show the various options though!

 

It takes about 20-30 seconds per tire for me to drop 18-20psi

 

Add another vote for the ARB/ Currie deflator. Fastest deflator I've seen
