Only shows pressure while pumping
"At first I didn't think the pump was working right, but I hopped on the live chat and Tristan told me that the valve is a one way valve and it only shows the pressure while you are pumping. If you stop pumping the valve closes and the pressure drops to 0 on the gauge. It was confusing at first since I didn't want to over inflate my packraft, but it makes sense now and is really easy. Thanks for the help Koko Crew!"
