been hunting for an inflator after my ARB one decided it would no longer give pressure readings accurately.. might give this JACO a shot. Thx @Zubail @Mike M.

Yes, try, at least last month it was giving quiet accurate reading compared with onboard tpms

It's a good one Luke. My ARB inflator took a seat at the back of the bus because of the annoying leaking. This Jaco is quite good but be sure to use the sealers they come with at the connection point and the inflation tip. 

For our RRs, the psi reading will always be +1 when reading from the car as they dont display any 0.5 increments. I have noticed this consistently with a manual gauge, the ARB and this Jaco. just as an FYI. I have not found one that gives me the exact reading as the display in the truck. A problem i can live with though

i can definately live with close enough.... my arb is between 5 and 11 psi off the TPMS and handheld guage at the moment which is a bit too far.

Thanks @Zubail yes i am using this, which i prefer over the ARB tyre inflator which leaks a lot. The Jaco has a patented deflating tip which does not leak, even when you move the gauge around. I recommend it as well for adjustments. 

For deflating, I have been using the below auto deflators for more than 2 years now and i can say they have been great. After a long-period use, i highly recommend it. You set the PSI once and you get the same results, every time. Takes usually around 3-4 minutes to deflate. What i do is i connect them first thing i park and by the time i have the flags up and a few quick hellos, the deflating is done. Hope this helps for anyone who is looking for an effortless deflating method.

Looks like you have a reliable set @Mike M.. Some of the reviews on Amazon indicate the same problem I had with my Staun's. Even though they are set exactly the same the results in 1 was always off then a 2nd one started going off to the point I had to inflate a couple of times on that one.

you should always keep in mind, that after driving deflated, your tires are hell hot, so while you are inflating 1st one, it will after few minutes show different, thats why I prefer first to remove flag, go say byes and thanks , and after that only start inflating 😀

Apologies, this was regarding deflation using Staun's. Inconsistent results and apparently the same might be true for some of the deflators Mike is using these days. He got a good batch. Still on the hunt for a consistently reliable deflation method that accurately stops deflation at the desire PSI.

Yes @Emanuel you are right. Giving off numbers has happened a few times. What I do after that is use the air gun for cleaning it and recalibrate. In case of sand I use alcohol but I never use lubricants as it would collect more residues with time.
Also to hit Some PSIs such as 15 specifically sometimes I have to calibrate it a bit higher. It does have these flaws.
As long as it goes back to normal operations after some love and care, I consider it to be normal due to sand. So far I didn’t have the issue where it does not go back to normal after a small maintenance….. yet .
In the 2+ years of use I did this maybe 2-3 times so it’s still ok in my opinion. 
so yes it has its flaws, but manageable I would say for the job it is doing.

As a side note, and inspired from @Frederic’s story on how @Srikumar used to deflate in his early days by visually looking at it when I first joined @Carnity, it inspired me to do the following as a good practice as well, not really related to the topic but helpful to spot if things are off.

When you have time, deflate 1 tyre to 11 let’s say and deflate the other tyres to 9, 8 and 6. You will create a visual memory after a few times to spot what “good” looks like vs if things are off. Just an idea which has helped me once to spot a mini pop out during the Pajero days after a side slope when the pressure dropped to 6. Hope this helps.

@ZubailYou should inflate to the desired psi when the drive is over but as a good practice check ur tyres again the next day or right after the wash in case you directly wash after a drive. You will always notice around 2 psi difference because that’s when the tyres really cool down. So my advice is always check ur tyre pressure first thing the next day as well and inflate as needed, as a good practice.

Yes, as I now it will go 3psi lower, till tomorrow, I'm doing 3psi up, so it's ok already used to it

And having tpms also helped
