Tech and Features: Newly engineered seals and pistons combined with newly molded handle and feet offer improved ergonomics and inflation speed. Single- to double-stroke inflation switch allows for instant change from high-volume / low-pressure inflation to low-volume / high-pressure. Custom WMFG kite tether and hook, kite-tuned WMFG pressure gauge, integrated sand filter, premium high-flow and extra-durable hose with new threaded fitting, and the widest range of kite nozzles of any pump on the market make this the finest standard-height pump ever produced. Not recommended for inflation higher than 13 PSI. SUP nozzle sold separately.
