Seriously, this pump is excellent and saves so much time. It starts out pumping normally, then it kicks into high-pressure mode to blow it up easily to 12 (or whatever you set it for), then it shuts off automatically. I actually bought a second one and have my XPlorer and Adventurer inflating simultaneously. When we're done, I deflate them while taking off the fins, getting the straps and bags ready, etc. roll the boards up and I am on my way.
