The Sportiiiis Heads Up Display boom from 4iiii Inovations attaches to almost any glasses and gives you a visual and audio feedback on critical performance criteria. You use PC, Mac, or smartphone software to program the Sportiiiis to respond to data from your current ANT+ training devices. With a tap of the Sportiiiis attachment point, multi-colored LEDs will light up to show when you are at, below, above, or dangerously above your setpoint. You can even hear an audible cue of your exact heart rate, for example. In addition to heart rate, you can monitor power, cadence, and speed with the proper ANT+ sensors (not included). The Sportiiiis Heads Up Display boom is $199.99; a boom plus heart rate monitor is $249.99. A heart rate strap, a foot pad sensor, and a bicycle speed/cadence sensor are available separately for $59.99 to $69.99.
