28mm 1/8BSP Thread Paintball Gauge, 3 Units (Bar/Psi/Mpa) Adjustable PCP HPA Air Gun Paintball Digital Pressure Gauge with Black Cover,Air Compressor Gauge Air Tank Manometer

They work quite well, hard to see in bright sunlight but, it's ok, great for getting a really good tune on the air guns.

More accurate than the other pressure gauge I bought at another store

battery lasted a week, hopefully just a dud

I've used 3 batteries in 5 days of time. I've had it on a total of 6 times, for 60 second each. Displays "BARS", after changing battery, it displayed "kgCM3". After 3rd battery and ome unknown number of button pressed it displays PSI. 3rd battery died in 3 minutes. No instructions This thing is messed up & random.

Ok so here we have a digital manometer for use with pneumatic air rifles, I’ve got to be crazy but what the hell…lol. If your even remotely familiar with these style pressure gauges you know, atleast in my experience that is, we can put a man on the moon but produce one of these that is accurate, reliable and has a life expectancy recorded in more then hours, good luck. So today in order to replace the I lost count of how many failed gauges, I thought what the hell, this should be fun. So we have a well made it seems, battery operated manometer with digital display. Using the standard CR something something button battery this is pretty much a straight forward install, simple unscrew old and install new. Easy to read gauge that’s backlit sure does beat starring at those tiny little numbers. So far so good, seems to be accurate, for now, let’s hope it stays that way. Hell it lasted over a hour now, that’s got to be good for three stars….LOL. I will return after some time and usage to update as to how it’s going.

The function is simple. I quickly learned how to adjust the unit and sleep time by following the video learning. Great

Easy to operate, very creative

Simple yet effective. I use mine on an air tank that I transfer to a PCP air rifle. I haven't had any issues yet.
