Heads-up display system Sportiiiis, from 4iiii Innovations, just got more affordable. The company just adjusted the price of its visual display system to $149 for a basic model. The heads-up display attaches to any pair of glasses, and sunglasses, to provide visual context to data such as heart rate, pace and cadence while running or cycling. If there’s a signal, the heads-up display will show you readings so you don’t have to take your eyes off the road ahead.
