Review on Large Dual Action Hand Pump by Coleman by David Fields

This article is a godsend. I used it to inflate both the air mattress and my 4 person raft. I can fill a raft in less than 1/3 the time it took me with the electric motor that replaced this pump. Get a simple workout by padding things. It's a little unwieldy, but physics say it has to be for this kind of performance. However, I can put it in my backpack and take it anywhere. However, I had to purchase an adapter for my raft as none of the nozzles that came with this pump fitted it exactly. So keep that in mind.
