I am looking for the smallest air gauge made for PCP air rifle. I have a couple WIKI analog gauges and and Edgun EDMU digital and have looked at the Huma and Sekhmet. I hate shopping on these sites. Spent a couple of hours looking at specs for the sizes. They don't list them very well. Probably knowing the answer but these just stick out to far from the tube. Has anyone found a better solution. Diameter isn't the problem, it's the thickness! Thanks
