Harry, the owner of Coyote is a good friend of mine. He is an engineer and he has a unique way of looking at things to discern the issues and solving the issues he finds. I've got a couple of hundred emails back and forth with him going over the nuance of how a deflator works and how each tiny little detail affects accuracy and repeatability. Everything from spring design to friction to o-ring and seal composition, to what effect the air path through the deflator has on accuracy.
Since he has taken over Staun to convert it to Coyote, we've had many conversations over the years and I don't recall many where at some point we didn't discuss some new aspect of how a deflator works and what he either has done or is working on to solve some problem. To say he is obsessed with air pressure, air gauges, tires, tire pressure and anything to do with that stuff is a very mild understatement. No one on the face of this planet knows as much about practical applications for air pressure and tires as he does and that isn't an understatement.
To compare the work he has put in on deflators and saying they seem the same as the crap knock-offs is like watching a bottle rocket at some 4th of July celebration and saying that seems the same as a cruise missile. Yes, at night from a distance that may be true, shed some light and shorten up the viewing distance and the similarities quickly dissolve.
The odd part of all of this is I don't use an ARB style, or even own a set of Coyotes. I use a simple screw on air release and a gauge. No muss, no fuss, they come in sets of 4 which gives me 3 spares since I air down one tire at a time.
