Ideal if you do not have access to an electrical source, this clever hand pump creates airflow on both the upward and downward pump movement, halving the exertion required with a more traditional designed hand pump.  It is great for inflating a wide variety of inflatable products from beds to boats and is particularly useful when inflating next to the water’s edge as it is not an electric based pump.  Dual action, it inflates and deflates rapidly, and includes a long hose for easier access to trickier valves, the hose includes double lock, Boston and pinch valve adaptors, and when not in use all items can be stored in the convenient carry bag.
