I've owned the August in-line regulator for about a year now, and I absolutely love it! It's an excellent tool for those with an unregulated PCP. Firstly, it's perfect for sighting in your scope, and secondly, it helps find the PSI that yields the best accuracy. I also use it when I'm set up in my blind for consistent shots time after time. While you can purchase a big bore regulated PCP these days, most don't match the power of an unregulated PCP of the same caliber. I'm planning to enhance its portability even further by ordering quick disconnects to replace the stiff hoses very soon.
