The power of multi-sport computers has become undeniable. After all, why should you have to own a different computer for each of your athletic disciplines? With the CatEye Q3, you're able to view metrics for your cycling, swimming, hiking, or running, all with the convenience of a wristwatch. While the Q3 is designed for multi-sport usage, it does include most of the functionality of CatEye's cycling line of computers. However, you'll find that the Q3 separates your metrics into three sets of displays -- upper, middle, and lower. At the upper display, regardless of if you're running, swimming, or cycling, you'll see current, average, and maximum speed displayed. And with the Q3's lap feature, you'll also be able to view your average and maximum lap speeds. For the Q3, CatEye ensured multi-sport functionality through the inclusion of a heart rate sensor. Additionally, the CatEye also included a cadence sensor. With these devices, you'll find that the middle display of the Q3 is dedicated to their readings. Accordingly, you're able to view your heart rate in terms of current, average, maximum, and average lap. And as for your cadence, you're able to view your metrics within the same aforementioned fields. At the lower display, you'll find that CatEye focused its attention on both time and calorie consumption. As a result, you're able to view various distance metrics, the date, the current time, lap time, and calorie consumption. It's also worth noting that the Q3 allows you to train within five programmable heart rate zones, and up to 99 laps. It functions on a 2.4GHz digitally encoded wireless band and is capable of storing up to 30 training files. Additionally, the Q3 features programmable time, distance, and countdown functions, and it's waterproof up to 30-meters. The CatEye Q3 is available in the color Black and in one size. Please note that each Q3 includes a wristwatch, handlebar mount, heart rate sensor, and a cadence sensor.
