Steven put D2 to the test during the 2014 Americus Cup hang gliding competition
in Georgia a few weeks ago and captured some great photos while in-flight. In
his own words, “D2 does everything a hang glider pilot needs.” In addition to
being able to upload his GPS track log for the competition, the ability to
display altitude, which features an adjustable barometric setting, provides
pilots with the most accurate altitude readout. As seen from Steven’s wrist, D2
also features a moving map display that utilizes a worldwide aviation database
so pilots can build flight plans and navigate with ease.
