Double-Pump 40Double Pump 40A two-stage pump. The primary stage delivers a huge volume of air per stroke. When the pressure in the boat increases and pumping starts to become difficult, a simple twist of the handle locks out the high-volume primary stage and locks in the high-pressure "top-off" stage.
This is the pump for you if you have an inflatable kayak or canoe. The goal in the development of the Double 40 was to design a compact pump, so that it could be stowed when space is limited.
