The three stages of the GRI HP6 Triple Action Pump utilize it’s dual cylinder design to maximum effect. Stage one see’s your down and up stroke ensures you take full advantage of both the high volume and high pressure pump cylinders. As you begin to fill your SUP inflatable with air, switch it up to stage two and expel air just on the down stroke, enabling you to use all of your body weight and lessening the load on the naturally smaller muscle groups in your arms and shoulder. Finally, stage three – utilizing the down stroke on the smaller high pressure cylinder only ensures you reach the ideal pressure of your inflatable SUP in record time, meaning less time pumping and more time on the water.
