These hilo pumps make it easy to pump large volume or high pressure by switching the mode on the base. You can pump your kiteboarding kite to 3psi quickly with large volume strokes then switch to high pressure to finish it to 8psi. Alternatively, you can start with high pressure on your inflatable SUP and get it up to 20psi. The mechanical advantage this pump provides you allows one handed pumping through out the process until the desired pressure is reached. -Phil Midler Whether it's moving the most air in the least time, or getting those last PSI's into your Kite & SUP - this pump does it with ease! Combining the best of a HIGH VOLUME HUGE PUMP and a HIGH PRESSURE SUP PUMP you can inflate in stages, optimizing your effort along the way. At the beginning, the Double Action stage moves 6.5L/14Gal every time you pump it. Once the object is full and you begin to feel resistance from the air inside, a switch to Single Action pumps air every time you press down, releasing the resistance when pulling up. This allows you to use your weight while pressing down to pump the first few pounds/PSI's into your inflatable (from 1 to 5PSI). The final stage works in the same way and adds the internal SUP pump to take the effort out of those last remaining pumps. Going from 5 to 25 PSI requires less volume and more force, a perfect job for the Pressure Booster stage!
