Giant Control Mini 1 Shock Pump

GIANT shock pump has a two stage connector. There is a large knurled thimble that you screw onto the shock first. Then once that's all in and fully sealed, there is a smaller thimble that you screw-in next - that pokes a nib to open the valve. You unscrew the thimbles in reverse order to detach the pump. There’s no chance of too much air escaping by accident.

Pros - good build quality and the pump handle is comfortable (large and round), and it goes all the way up to 400psi (I guess for the newer higher pressure shock designs).
Cons - the high capacity 400psi dial vernier markings (smaller and closer together) makes it harder to accurately place the needle for pressures under 100psi (for my front forks). It's also big, so not exactly something I'd bring on the trail with me.

But still the best pump I've got to date. Takes away the stress and drama when removing the pump - and I know for sure that the pressure in the shock is precise and more importantly, repeatable.
