The Suunto Advizor - featuring a Heart Rate Monitor using Suunto's proprietary HR technology - simultaneously shows your heart rate, altitude, and vertical ascent/descent data. The Advizor memory stores your total training time and your maximum, minimum and average heart rate during training - plus your time spent in / above / below your pre-set target heart rate. There's even an audible alarm to alert the user when your upper or lower heart rate limits have been exceeded.

The HR belt features a user-replaceable battery so you no longer have to send in your belt when the battery runs out.
