GEAR GUIDE: Acumen HRM

Features:

Time of Day - Displays time and date with alarm features. Use a 12 or 24 hour clock system. Set daily alarm. Watch returns to Time Mode automatically when no heart rate is received for 5 minutes.

Heart Rate - Displays ECG-accurate current heart rate when transmitter belt is worn. Set your Target Heart Rate Zone or determine your zone automatically with the EZ-Set Target Zone feature.

EZ-Set Target Zone - Determines personal heart rate limits for an exercise session. The EZ-Set Target Zone feature can determine an individual light to moderate intensity exercise zone (65-85% of the maximum heart rate). The Acumen Heart Rate Monitor will automatically calculate lower and upper heart rate limits limits based on your age-predicted maximum heart rate (220 minus age). You can also program your own Target Heart Rate Zone with user defined values.

In-Zone Goal Countdown Timer - Set 0 - 60 minute timer to begin when Target Heart Rate Zone is reached.

Calories - This feature in Acumen Heart Rate Monitors estimates the number of kilocalories expended during exercise based on heart rate and inputted exercise intensity index. An Exercise Factor table is provided to assist individuals in choosing an exercise intensity index. Displays estimated calories burned when receiving heart rate signals.

This is mainly for fun, to see how hard my heart's working, how quickly HR drops post-exercise, etc. The highest I've gotten it is 200.
