How much do you trust the gauges in your airplane? Scores of preventable accidents result from pilots miscalculating the amount of fuel they have remaining in their tanks. Place your trust in the Fuel Hawk.
Made of heavy, clear plastic, each "Fuel Hawk" works like a drinking straw. Place it in the fuel tank until it touches the bottom, put a finger over the end, lift it from the tank and read the graduation markings on the side.
Direct readout indicates usable gallons on a calibrated scale. Simple instructions explain how to calibrate your gauge by using the calibration card along with a known quantity of fuel in the tanks. 11" long.
