Isokinetics Inc. Brand Exercise Ball Air Pump - High Volume - Heavy Duty - Pumps on Up and Down Strokes - Multiple Nozzles for High Air Volume Inflatables - 2 Color Choices;

For a video demo, search YouTube for "isokinetics inc". Our biggest, sturdiest model. Good for exercise balls and other inflatables requiring large volumes of air. Has a well anchored hose to handle higher pressure situations and 4 nozzles to fit almost anything. Built for heavy use. Notes: You need your feet to anchor it but because of its larger size you don't need to bend over as much as other models. You can tell by using it it is built for heavy duty use. Our test only took 75 up and down strokes and less than 1.5 minutes to fill a 65mm exercise ball. One feature on this model that may be handy is the way the air hoses lock in place. If you have higher pressure inflatables or you want to put all your weight into pumping it, this will keep the hose in place and not pop out under pressure. It also deflates, which is great for shrinking items down as far as possible for storage.
