new SUP pump coming that's easier to get to 15psi and beyond, posted info on the zone:
they have produced a new model of that pump that's a bit taller and thinner, so it's easier to get an inflatable SUP pumped to 15psi and over, I expect most brands will switch to the new model for 2013
max pressure 27.5psi
volume : 2000cc
size : 11 x 22.5 x 59 cm
volume is a little less than the current popular model, so the initial 12psi or so will take a bit longer, but after 12psi this new model will be way easier
this one is also single action only, like the current model, so should also be a very low maintenance reliable pump.
