I keep hearing that fat tyres are very sensitive to pressure and given they are run at 15psi or lower what are people using the check the pressure?
Thumb and forefinger or something more accurate? I'm not convinced my pressure gauge is that great with a Presta valve
I had an Oxford digital guage and set mine to 10psi. But it feels a lot more solid than some other bikes 10psi so I'm not sure.
these are supposed to be the dogs danglies of fat tyre pressure gauges, distributed by QBP (Salsa, Surly, etc) but they don't have an importer in the UK at the moment.

Car ones are cheap and should work fine
The pressure gauge from schwalbe works ok at low pressures, but the best i have found is the gauge on my joe blow fat track pump. Most pressure I have run so far is 9psi, which is ideal for most trail centre blasting and racing, don't need anymore otherwise I'm getting bucked off it, 6 psi worked well in the snow but it wasn't deep just wanted more traction.
I used a trials gauge

Measured against an old school gauge where the tube pops out like your dad had it was about 1psi different.
Plus the air release button was useful.
Started out at about 15 and rapidly settled around 8psi. My expensive track pump couldn't cope with those pressure readings.
I have a trials guage but never use it. Pump up (or let air out) until the tyre wrinkles a bit when you pull on the front brake and bounce on it. This is tubeless though, tubes will need a bit more to avoid pinch flatting.
I have a trials gauge too. Generally only use it to set up a tyre the first time so I know what the right amount of squish feels like.
I bought one of [url= http://www.fatbikes.com/search.php?search_query=gauge&x=0&y=0 ]these[/url] when I got my Fatty. It worked just fine.
But I prefer the digital Schwalbe one like this as it reads in 0.1 psi increments.

Same as normal tyres?
Add a bit, let a bit out see how it feels. When you get what you like remember what it says on your gauge?
any good for you, works for me but mates are stumped with those silly skinny tyres when they come round.
