Thought I’d try out a floating dock. Bought a $70 pump on Amazon but after 40 min it was only at 9.5 psi and then it stopped and gave me a “U/L” message which I assume means overload. (The dock is 8’x10’.) Pump was supposed to go to 20 psi and I set it to 10. Floating dock is supposed to be at 10-12 psi. I’d like something that’s good quality and doesn’t take forever, has a gauge or other readout and preferably auto shut-off but not necessary. The dock is the only higher pressure inflatable on the boat. Anything you know of that fits the bill?
